Two batteries naming issue ("Battery 0, Battery 1" instead of "Battery1, Battery 2")

Q: Two batteries naming issue ("Battery 0, Battery 1" instead of "Battery1, Battery 2")

Hi guys. I have a T470 and after the latest Windows update I encountered a battery naming issue. Before the update batteries had proper order and were named accordingly: battery 1, battery 2, no surprises here. But after the update I noticed the order has changed to battery 0, battery 1 (attached pic below) Yeah yeah, I understand arrays start at zero but what is that? I was just wondering is it just me or you guys have the same situation going on with your batteries? Is there a way to change the order back to "normal"? .

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

Battery Issue - Lenovo V570 (Laptop) - Battery Model L09S6Y02

First off I for the most part do not use the battery. It is normally detached from the laptop. I only attach it to periodically charge it and test prior existing charges' performance.

O.K. here is the problem. I attach battery attachment, computer does not make it to the window screen more often than not. When it does, it freezes at the please wait loading screen.

I rarely use the battery at all, but I want all my equipment up and functional. It's life should still be good for I periodically recharge it. I think since I've had the laptop I've only recharged it a total of 6 or 7 times and that's been a year or so.

I, for the moment at least have the battery working power adapter attached. What did I do? I uninstalled Avast (freeware version) ?

I learned from prior experience that running two of any system utility software can cause problems, but it normally restricts itself to what it is protecting. Then I remembered: "If you remove the possible whatever is left however in probable must be the truth."

Next phase of testing is test the battery on it's own.

Hey, I really need help. I'm having problems with my laptop. It's a dell inspiron 7559 and was bought around January. Recently I have seen that the battery has no longer been as hot as it used to be when I first started using it. Along with the sleeve on the tip of the screen power adapter (below the part where the adapter lights up) has started to come off, exposing the wires. The battery has continually dropped down its percentage rate ever since I bought it, and it won't go back up. It is currently at 0% battery life and it says when you highlight over the battery icon ( plugged in, not charging). It also happens to show the BIO setup when I start the computer and shows that the batteries wattage and type cannot be determined. In the BIOS setup, the ac adapter type is unknown. The battery has not been through any harsh conditions along with the laptop. I have tried removing the battery, starting up the computer with the ac adapter (which is 130 watts), then adding the battery back, and ac adapter, then turning it on, but it had no effects. If I remove my ac adapter while my computer is on ,it instantly turns off. If someone can support me with this issue, it would be gladly appreciated. Thanks.

Wrote a month or so ago about a faulty U330 battery.  I replaced it with a new one and am having the same issue--rapid discharge. For example, the battery power goes from 100% to 95% within 3 mintues, from 95% to 73% within 15 minutes.  With the original battery, I noticed that its power could stay at 0% for quite some time before the computer shut down. The battery lasts a decently long time, but the real issue is that I pretty much have spontaneous shutdowns since I can't predict the actual power remaining. Could this be a Win 7 issue and not an issue with the battery's actual capacity? Any other suggestions on how to fix this? 

A:U330 Battery Issue--New Battery, Still Discharging Fast

Hey Gurbly,
 
Curious to know is the replacement battery that you bought is it from Lenovo or is it a generic brand battery ?
 
If this is a Lenovo battery, might I suggest the following link :
 
http://forum.lenovo.com/t5/Welcome-FAQs-Knowledge-Base/How-can-I-increase-battery-life/ta-p/244800
 
If the above does not help, could you try the following.
 
1. Replacement Battery to be drained.
2. Replacement Battery to be fully charge. During this time do not turn on the U330
3. Once fully charge, turn on computer and login to your operating system. Do not launch any application and if possible disable any apps that auto starts.
4. Change the power management to "do not turn off hard drive and monitor" when battery is used
5. Adjust screen brightness to 50%
6. Leave the laptop idle,
7. Check within 3-5 minutes if the battery level drops from 100% to 95%
8. record your finding and reply back.

Hey there,
I've been using my upgraded Inpiron 17R SE happily for a couple of years by now. I've even gone as far as buying an 128GB SSD to futureproof it. This is the only drive - besides the DVD drive - currently present in the laptop. However I've had an issue for quite a while:
Whenever I try to boot the Laptop only using the Battery (even fully charged) it Posts then loads Windows and turns of just before the Login-Screen (I can't see it). When I proceed to turn it back on, it Posts then beeps and says that there is a Real Time Clock Error and gives me the option to proceed booting or to enter Setup.
This however doesn't occur when using the Power-Brick. Moreover it isn't always the case. Sometimes the Laptop boots and works fine just using the battery, but then upon opening a Programm (while under battery-power) it shuts of and gives the same error message again. If it decides to work the battery still lasts for 2-2.5 hours.
I'm really confused to what the problem is. It could be a power delivery problem, but it's still the original battery and laptop with only the HDD changed to a SSD.
I'm aware of it being a rather old machine, but selling it is my only hope for getting a new laptop for college, but I can't sell it in this state. 
I'm at a lost and really really sad because of this issue. I'm sorry for any typos or grammar mistakes, I'm a non native english speaker.

Thanks for reading this. i have never posted anything in my life but i am stumped and need some help!
I got a dell inspiron 2200 and one day i was running it while it was pluged in and i unpluged it and the laptop just "Bloop" shut off......i tried turning it back on but nothing. just as if i had no battery in it at all. when i pluged it back in it fired up like normal i checked the battery meter and it said 97% full then charged up to 100% full but still it wont run off the battery. as soon as i unplug it it shuts right off.

Someone told me to run the battery calibration but my bios doesnt have an option for it. at least i cant find it. i know it has it somewere because when i first bought this laptop the screen was broke and when i bought a new one for it and booted it up it said i had to run the battery calibration befor it could start "not sure why" but i did...watched it drain and charge. so i know it's in here somewere. do you think this would even help?

Also i think i updated the bios so it might have had an older bios witch might have had the battery calibration and the new one i put on doesnt. It has verison A07 now. i tried "downgrading" to A05 and A06 but it doesnt let me, Says i have a newer verison and cannot install an older verison.

Stinks. this problem kinda takes the "Mobil" feature out of a laptop. Any help would be Awesome!

A:Laptop battery issue ??battery calibration??

i'm afraid the battery calibration program is only used to initialize new Li-Ion batteries which need to be prepped with an initial charge-discharge cycle.

It sounds to me like you have a battery composed of 32 (probably AA sized) cells.
One of those cells has died and hence you see only 97% charge. Unfortunately losing a single cell prevents current from entering or leaving the battery so your battery will not discharge correctly therefore shutoff without discharge.

I think you need a new battery. Although it may be possible to replace the single bad cell, other cells may be degraded also - if one cell failed, why not others? unit could have been exposed to heat etc.

Although I was an engineer for Gould, I am not a battery expert!

good luck!

Yesterday my laptop (Acer Aspire 5050) was on but I had the lid closed. I laid it aside and somehow the ac adapter was disconnected at the converter box and the battery ran out. When I turned on my laptop today, it was a really slow startup (normally it only takes 1 minute), the arrow/pointer was frozen, and the battery/plug icon had a red X on it with the battery showing empty. I restarted the computer and was able to hover over the icon before it froze up. It said battery was 1%, plugged in but not charging. I checked the battery, it was secure. I tried taking off the battery and putting it back on. It was then showing a green battery & plug, and 100% charged. But whenever I hover over the battery icon, the red X and empty battery icon comes back, but it'll still say 100% fully charged. The computer will function properly until I turn it off and restart. Then I have to do the same process of taking off battery & putting back on before the pointer/arrow will unfreeze and I'm able to use the laptop.
Any ideas what is going on?
Thanks!

My year old Averatec c3500 notebook was stored for a couple months. When I started it the main battery was empty (of course). and the clock icon showed time/date that was way off. I considered this probably normal.

Now when I store the PC for even three days the clock needs to be reset, although the main battery seems to still have at least a negligible amount of power left (will show a short slideshow of photo's.)

I have two questions:
1. Is there a small CMOS battery that might need replacing ? and does that battery get recharged from the main battery? Where would that be located ?

2. What is the best way to refresh my main battery? I have opinion if I totally discharge/recharge it will come back to total storage.

Hello. I have a question. Regarding Battery Backup UPS systems, having a dual or 2 batteries incorporated into the unit better than having just one battery? They are usually 12 volts each.
Under typical conditions, regardless of the wattage needed; would the runtime (running due to loss of power) be increased or not? ...but how? Is this significant increased in runtime or not? It is truly worth having a second LEAD battery backup in your unit?
Please reply.
Thank you!

A:Having 2 Batteries For A Battery Backups System Work Better Than 1?

Having a second battery will increase either voltage or capacity, depending on how they are wired. Hooked up in series will increase the voltage, so 12V > 24V system. Parallel wiring will increase the capacity and thus run-time.

Hi,
 
I'm running Win 8.1 on a tablet with a dock that has a seperate battery and I'm having an issue where the docks battery will be completely used up and then will not charge unless i remove the tablet and jump start the battery in the dock so to speak.
 
I would like to be able to set a reserve battery level for the docks battery specifically but Windows seems to pool both batteries together while acknowledging them both as seperate.
 
Is it possible to seperate the batteries so I can have a reserve battery level for each one individually or is this a hardware issue?

Hello. I have a question about battery backup systems or UPS where now they have a sealed pack of 2 numbers of batteries as 1 battery.

I know that having a second battery will increase either voltage or capacity, depending on how they are wired. Hooked
up in series will increase the voltage, so if a battery is 12V, then your will have a 24V system or unit. Parallel wiring will increase the capacity and thus run-time.

Now, if the the 2 connected batteries ARE tied together as one unit, and the batteries ARE wired in a "SERIES" circuit, HOW CAN 24 volts ANYWAY improve run-time versus 12 volts? (BECAUSE THAT IS HOW I AM FINDING THEY ARE WIRED -- IN "SERIES"; IT DOESN'T MAKE ANY SENSE.) Can it provide ANY positive effect to run-time? Doesn't it REALLY NEED to be wired in PARALLEL in order to increase run-time?

Please reply.

Thank you!

A:Battery Backup Systems Or UPS - 2 Batteries - In Series Circuit - Bad?

Hello.

I have come to a conclusion after reading and speaking to people. There is no difference between the different circuit runtimes. I was failing to see that both series and parallel circuits have the runtimes when converting from DC to AC. I was getting hung up on the differences between volts and ampere effect on runtime. However during runtimes, I found that the cells discharge twice as fast alone in a parallel circuit to get the same amount of amps at 120 volt output (required for AC) than a series circuit. However, comparing total runtime to discharge between a parallel and series circut -- they would be the same total runtime.

So there are two factors that I failed to realize: 1. There is an inverse realtionship between amps (flow or volume of current) and volts (pressure or strength of a flow or volume of current). So if I am trying to evaluate one or the other measurements because of this inverse relationship there, there was never any constant for me to do so since they are opposing each other -- so it cannot be done. 2. I was converting from DC to AC current (What happens in a UPS during power loss.) so there was a constant I had to relate to household voltage (120 volts) -- both kinds of circuits have to be in agreement when the constant is nominal house voltage (AC need to power your compoents for power loss. Being that the AC is what is end energy being used (1 amp at 120 volts), both kinds of circuits have to produce the same total power. Either way you w... Read more

I have recently gotten an X220 and couldn't be much happier with it, especially considering it's a laptop from 2011. However, I purchased a few new batteries with it, an original 6cell one and two 9 cell ones which are not original units, and these wear down extremely fast; about 40% in half a year approximately. I don't keep them charging when fully charged, nor do I run them down to almost 0%, so I am not sure what causes this extremely high wear.  Now I expected the non-original batteries to wear down pretty fast, but not this fast. Could it be that I'm using a 90W adapter? Does this charge on a higher voltage/current which these batteries cannot handle? I've measured the voltage of the adapter, and it runs at 20.5 volts when not connected to the X220, so that seems ok. Any ideas?

Can someone help me with this problem? So I just received my brand new Dell Inspiron 15 3000 and the battery is not charging. It says it's "Plugged In, Charging" but it never goes up and stays at 0%. At first I thought I just need to plug it in for several hours but it's been 5 hours now and still the battery stays at 0%. I tried running the BIOS Diagnostics just to see if there are problems and there's none. The battery status says everything is running normally and the Battery State says it's Idle. I tried draining the flea power several times, removing and reattaching the battery, but to no avail. I'm getting really frustrated and I'm really close to throwing this laptop back to Dell. 
I read somewhere that I have to update the BIOS but it won't update unless the battery is charged at least 10%. Someone also suggested that Windows 8.1 is causing the problem. I haven't even started using this laptop and it's already giving me a *** ton of problems. Any help would be much appreciated! Thanks guys! :)

Thanks in advance.

A:What will happen when i replace my dell 40WAh battery with 60WAh battery for Inspiron 3521?

As long as the battery is otherwise compatible -- and you realize it will increase the weight AND the size of the notebook (while the 4-cell likely fits entirely inside the system, the 6-cell will protrude from the back of the system), you will be fine.  There's also a big reason (safety among them) why OEM batteries cost more than third-party knockoff units, if that's a consideration.

Hi ! I need help to determine if I just plug in the samsung evo850 drive with oxdygx cable, onto the motherboard, with the UEFI-bios ask me to initialize the evo850 dirve?  If yes, after format the evo850 as GPT, will the bios manage the 512g pcie ssd as C drive (with windows 10 in it) and evo850 as D drive (data disk)?  
Another question is whether hdd password can be managed by the uefi-bio just like the legacy bios?
Also whether a similiar hdd password can be used on 512 pcie ssd?  

A:newly purchase xps15-9550 pcie 512g ssd 84 wh battery - try to add evo 850 on to the hdd slot, take out the 84 wh battery

The initialization takes place under WIndows - NOT in setup.  UEFI will detect the drive, but you must use the disc manager to partition and format it.

Hopefully you realize you'll need to replace that 84 W-H battery with a 56 W-H unit (the drive needs the space occupied by the extra cells in the larger battery).
Your existing C drive will be unaltered - if you have no other drives attached, the new drive should show up as D>
You should be able to set a password on both drives -- that said, they're not of much security (they can be removed and once that's done, the data is open for access).  Effectively if you have a need for security, drive encryption (bitlocker if you have 10 Pro) is a much, much, much better idea.
Also be advised:  the hard drive password ties the drive to the system.  If for some reason the mainboard gets damaged, the data will not be accessible without the intervention of a data recovery/password removal service, so backups - of both drives -- are ESSENTIAL.

Hi,
I have a Dell M5510 precision laptop for business.  Around January 2017, 7 months after owning this laptop the track pad started to come loose. At first I didnt know why, it was very minor, then each month it started to come off more and more. Around 2-3 months ago I stopped being able to use some of the functionality of the trackpad. I finally took the laptop apart to find out the battery had expanded and was causing this issue.  I purchased a M5510 with every upgrade (xeon, 4k, larger battery etc) and figured I would not have any issues as I use this for work. Has anyone else had similar issues on the M5510 Precision series?
It looks like the battery is very swollen in multiple cells and the trackpad looks like its about to blow right off the laptop.  
I'm also not sure how safe it is to use this laptop for business travel now that it looks like the cells are expanding and lithium ion explodes.

Hello everyone,
I have been having a problem with my laptop recently. A few weeks ago my laptop turned off, and wouldn't turn back on. I did some googling, and found suggestions to remove the memory, SSD, and CMOS battery, wait, then put them  back in and try again. When I did that, it didn't work the first few power button presses, but then it turned on. It has been consistent like that. I have the battery out, and on AC only, when I remove AC and CMOS battery, then plug the AC back in, the laptop will boot after hitting the power button a few times.

Any suggestions?

The battery light on my Latitude 7370 started to flash in orange and the laptop is not using the battery. It does not start when the AC is not plugged, and shuts down immediately after the AC is unplugged. However, the Dell online diagnostic test for battery passes it as working OK (the test for motherboards also passes). In BIOS, I can see the battery as 100% charged; however it also says "Health: Communication Error". A week ago the battery still had enough charge for up to 5 hours of office work. I have tried to unplug the battery, start the laptop without it, and then plug the battery back. I have also tried unplugging and plugging back the CMOS battery. Neither of these helped at all. I have been using the laptop with WD15. The behavior persists on 2 different WD15 units as well as on the default AC charger.

The issue is when the charge plug is plugged in and hovering over the battery icon it says that battery is charging.  However the battery is not charging but discharging until the laptop switches off.  The only way for the battery to charge again is to deplete the battery until the laptop is unresponsive when the power button is pushed to switch lap top on.  Once there is no residual power in the battery it will start charging again to 100% after which the cycle repeats, discharge.
Things I have tried.
Latest Bios update - no change
Another A/C charger - worked ok for a few days
Replaced battery - no change
Bios settings - reset to default (info related to battery and A/C charge reports all good)
F12 - Dell diagnostics, reports all good
When Battery is disconnected the laptop works normally
The laptop charge socket seems tight and secure
I have searched the internet exhaustively but have not found this same issue reported.  The only feasible way I can use the laptop is to disconnect the battery.
Can anyone suggest anything?

Just received a new Dell battery for my laptop.  The battery icon starts out at 100% and time remaining at about 3. 5 hours left, then within 1 minute the time remaining levels off to about 2 hours left.  The battery showing time remaining is jumping up and down.  I am only using the computer for the internet.  No CD or DVD or gaming.  At best I get 1.5 hours out of a charge.  Is this normal?  Or did Dell send me a bad battery?

Sincerely,

Lou

Hello, Lenovo Community, I recently tried updating my battery's firmware. It was going smoothly for about one minute until my charger disconnected and my laptop's battery died and will not charge. My charger has a long history of automatically disconnecting (two blinking lights, one white and one orange) so I cannot power my laptop through the charger itself. I really don't want to get the port checked, so I am looking to see if there are any other ideas from the community.  Here is what's happening:-My charger disconnects everytime I try to boot now (used to disconnect before loading Windows 10)-My battery is disconnected from the system (electronically, not physically probably)-I really cannot power on the system.  Thank you, Lenovo Community!

Hello.  I would be grateful if someone can help me with solving the following battery issue.
My XPS13 9343 (with Windows 10, 2015 model) recently stopped charging when connected.  I have conducted BIOS test, stress test, system test, battery test recommended on Dell forum, but could not find any issues.
Then ran device manager and checked & updated drivers, tested for virus, scanned the system, but could not detect any issues.
Lights on AC adopter is on (static) , and the front light under the touch pad turn on white briefly when connected then turn off immediately when plugged in (when disconnected, orange light comes on).
It seems charging is disabled...I might have touched keys without realizing (I checked whether there were hot key to enable/disable charging, but could not find one).
Since it is an ultrabook, and the battery has no issues, I have not opened the back to take out the battery.
I brew into the connecting hole, but it did not solve the issue.
Please help!

Dear ejn63,
Thank you very much for the quick reply.
I just did F2 at powerup and found the adapter was displayed as 'Unknown.'
I would order the new AC adapter today and see how it goes.
Will report when solved.
Thank you again.

Hi everyone, Title says it all, I know this topic of discharging internal battery first has been brought up a lot, and that the reason behind it is this: The T470s are designed to drain the battery with least wear first so as to degrade both batteries equally and prolong the laptop's overall battery life. However, as I'm using a new 61++ battery, clearly somethig is going wrong somewhere as the year old internal battery cannot be in better condition than the brand new external.https://gyazo.com/6c12f3f40514599d04d852a8589189ab Any ideas? Thanks!

The battery status toggles between not charging, not used, and unauthorized battery after it was calibrated using one key. Before that, the battery was working perfectly, lasting close to 5 hours. Now the laptop shuts off when unplugged and the battery status is constantly changing. I've had this laptop for approximately a year now and it was unused and left in an unopened box for the first 8 months.

After a round of Windows updates, I went to turn on my laptop and recieved the "Primary internal battery (601)" error.  After this screen, however, Windows would not load.  I have tried taking the battery out and 'draining the charge',  and starting up the computer plugged directly to AC with no battery.  Windows still does not load.  The start-up test in the diagnostics menu said the battery needed calibration, however when I go to run the battery test, it gets to "waiting for battery to charge" and exits out of the test without giving me any results at all.  Currently when turning on the computer I no longer get the "primary internal battery" error, it just goes directly to a black screen with blinking cursor.  Any help is appreciated, I'm completely at a loss here!

Despite the manufacturer's claim of 7 hours battery life on my Lenovo Ideapad 320S-14IKB - 81BN (S/N: MP1CHQTJ), I only get around 3-4 hours. This is with light usage, Reddit, a little bit of youtube etc. CPU usage was mostly around 0-5% the entire time. This was with the max CPU state in power settings reduced from 100% to 85%. However, I do have the screen at 100% brightness. As a different test, I tried doing (almost) nothing (apart from keeping the screen bright), and got 6 hours out of the battery. Is there a simple solution to increase this? It's only a 30 Wh battery (2 cell). Maybe in the future, a 60 Wh (4 cell?) one will come out for this model?

Ok this might be easy..it might not (COMPAQ M2105)

I ended up replacing my motherboard for a model with more features (SD readers blah blah).

I took it all apart and put it all back with the new board in...now when i go into windows (and even before while booting)...the orange lights would come on for a second...then beging to flicker

while in windows...it just will either not charge the battery..or flicker from AC to battery

i CAN power the unit on with the battery alone, and i CAN power the unit with the cord alone...

lastly, my old motherboard (which had a HD connector problem)...still WILL charge the battery...so i'm sure its not the battery...i don't think...

i also dont' think its the AC adapter since it is the same piece I used on both motherboards.....

what to do................

Hopefully you are experienced in working on and repairing laptops/notebooks... and you carefully handeled the replacement motherboard and didn't damage it. Repairing laptops takes considerable skill and caution.

It does sound like the "new" motherboard is bad unfortunately. How did you handle the "old" operating system restore to the "new" motherboard?

My original 9 cell Lenovo battery pack dropped from 3 hrs to 2 hrs capacity after a couple of years. So when it stopped working, "battery not detected", I thought it was forced into retirement due to low capacity. In fact I opened the pack and all cells were unexpectedly within millivolts and were good to at least 2 Ah. I get an aftermarket 9 cell pack, and it arrives with zero volts. eBay seller quickly sends me another. But the W540 cannot detect it. I order two 6 cell packs from two other vendors. None are detected by the W540.So it strikes me maybe there is something wrong with the connector, and not that the handshakes had failed by these aftermarket manufacturers. Lo and behold, the two positive pins on the laptop were bent, and so was the plastic tongue. It turns out that you can gently force in the battery and hear the double click of the lock, and due to misalignment, normal insertion would bend the pins. No connection will be established if the male pins on the laptop are bent. After straightening them, which breaks the plastic tongue guide, I was able to insert the battery and the battery is now recognized.So if you get a "battery not detected" error, before suspecting the cells or the pack, you may want to check the male connector pins on the laptop and make sure they are all straight. Also check the female connector on the pack as that can be bent, or the female connector pushed into the pack. I believe the alignment of the battery connector is a bit off with res... Read more

Ever since yesterday I've had this problem, I tried several solutions and none of them worked. Basically the problem is: The laptop only works on battery now. When the battery is at 0% the laptop turns off even if the AC is plugged in. To make matters worse, when the laptop is on I get this message "plugged, not charging". So basically the AC no longer works by itself and only charges the battery when the laptop is off. Here is what I tried so far:- Changing the settings on the Lenovo Energy Mangement tool- Uninstalling the Lenovo Energy Mangement tool - Taking off the battery and AC, pushing the power button for 30 seconds, putting them back in and turning on the laptop.- Starting the laptop on safe mode- Praying to God None of these things worked. Somebody help.

HP laptop 6830s, windows XP1) I had my laptop on standby and forgot to connect to the power source overnight.Next day I noticed the amber battery light flashing (checked the manual which said its because the battery reached a critically low level). I have turned on the laptop whilst on the AC source and is working fine. When I click on the icon it says:current power source= ACpowertotal battery remaining: 0%below this there is an icon of a battery with a red cross - when I click on that icon I get another window and it says power state is on line. Any suggestions?2) If this is an indication that the battery needs replacing, can I keep using the laptop with the AC source??

I am dual booting Windows 10 and Linux (Ubuntu 17.10). I was on Windows 10 when I was updating my battery firmware using the Lenovo Battery Firmware Update Tool. It prompted me to update my battery and I confirmed and clicked next. Immediately, my screen turned black. I waited 10 minutes and then did a force shutdown on the computer by holding the power button. Now my battery won't charge. It is an official 55+ Lenovo battery and last week Ubuntu's acpi said that the battery was at 67% capacity and could run on battery for an hour and a half at full charge. Now all of a sudden, after the failed firmware update, my battery will not charge: whether the laptop is on in Windows 10, on in Ubuntu, or while the computer is turned off and plugged. When I do connect the AC cord the battery indicator blinks with a steady green, to a stready orange, to a rapid orange, and then off within a span of ~10 seconds. I have tried deleting the battery drivers on Windows and restarting and it does not work. I have also tried to update the battery firmware again using the Lenovo Update Firmware Tool but it repeatedly gives me the same error "The tool was unable to update the battery firmware due to an internal error." I have also updated to the latest BIOS to no avail.

Hey there,
Yes you read it correctly: I have just received mine, which I purchased because of battery life and overheating and fan noise issues on the Dell XPS 13 i7 7th gen. The 8th gen was supposed to have solved all the issues the previous version was plagued with...
Well... I unboxed it, loaded all of my softwares, installed all the WIndows updates, Dell drivers, you name it. Charged it and started using it. When I unplugged the power cord, first estimate was 4hrs on the Windows battery indicator. Then I installed BatteryBar to have a more reliable estimator. Same.
Later on, I discovered a very strong and very loud fan. Unsurprisingly, the underneath was burning hot.
Got the support team on the phone, whilst I was talking with them, the fan kicked in and I even could give them a glimpse of how loud that was over the phone.
Has any of the lucky owners of the XPS 13 i7 8th gen come across similar issues? 
Sometimes, I am just baffled by the world there is between the promise and the reality....

A:XPS 13 8th gen i7 16GB RAM QHD+ Battery Issues 4hrs battery life tops

A brand new system may have an unusually high level of background tasks running simultaneously, such as Windows and other applications checking for and downloading updates, Windows monitoring your usage to optimize technologies such as PreFetch for your usage patterns, etc.  You might want to conduct a battery test after things have settled in a bit more.  The QHD+ display takes 2-3 hours off of the expected battery life, but you should still get 7-8 hours under normal use.  Then again, if you're heavy on WiFi and max out display brightness, you'll get less than that.  The fact that the fans are kicking on also suggests there's an unusually high level of background activity running, so check Task Manager to see if you can find out what's responsible for that.

Hi, my original Lenovo, Japan cell, 9-cell battery shows these data in linux upower utility:- 86% of designed capacity- 63% chargedIt was holding my computer 2-3 hours normally. Computer is bazar refurbished, probably new piece, never used, stored in a warehouse in a big company. Now X200 battery led started to blink orange, and batterry gives no power, voltage measured 0.02V. I tried also charging via X200 dock only, nothing happens. So I suspect this is internal battery electronics causing this. I have three 65W chargers, 2 docks. I found a video of some guy overriding internal electronics by short voltage pulse to the output terminal, but I don't want to dissasemble the battery. Questions:1. How can a utility in linux tell charge data, when battery is measured ~0V? Is there any background communication and data is taken from some system bus?2. Is there any power cycle limiting, how to get these data?3. Battery showed good health periodically during usage, even now @ 86% of designed capacity, this seems like early cutoff?4. What exactly does that orange led mean, how to get additional data?5. Why should a battery with good health, not over discharged, stop working? Thanks to everybody.
