Battery Charge-Discharge cycle issue

Q: Battery Charge-Discharge cycle issue

I have been getting this weird charge discharge cycle on my Pavilion 15. I pretty much have my Laptop always plugged in. A couple of days ago it shutdown in a blink even though it was at full charge. Then it would'nt start even when I pressed the power ON button. It started after I took out the battery and put it back in. Ever since then its trapped in a cycle where it always shows "2 mins to charge" in the notification icon and a certain percentage. Then when the percentage hits 100 it stops charging and instead discharges gradually even though it's plugged in. When it hits 0% it shutsdown again and won't start till I take the battery off. Can someone tell me whether this is a problem with the battery or the charger and how can I fix this. Thanks

I have done the custom settings for battery from dell power management. I have set that the battery should start charging when it is at 50% and stop charging at 80%. When the battery has charged 80%.It has stopped charging. But the discharging of the battery is not happening itself. I have to remove the ac power so that the laptop should start using battery instead of ac power. The battery should self discharge when it reaches 80% and start charging when it reaches 50%. which is not happening currently. Can any suggest any solution.

Please reply to this post if you are experiencing the following discharging problem, or would have a perfect solution to it. Many thanks in advance  When on battery, the Internal Battery discharges First, then, the External Battery. I got the machine around a week ago, and my internal battery has already gone through 8 cycles (when reviewed through the Thinkpad Vantage App). Yet, the external batter has only gone through 1 cycle. Given the ease of replacing the external battery, and that Thinkpad advertised a "hot swap" battery bridge feature, I do not find a rational for the current discharging behavior. There is a relevant posts on Reddit, but draining both of my batteries does not get things back to normal.External link: https://www.reddit.com/r/thinkpad/comments/83vqj5/t480_internal_battery_draining_first/

 As this is my first post,  Hello all! I'm a longtime Thinkpad user, appreciating my previous T60 and T400 for their repairability and durability.  I've just bought a used thinkpad t430s, and I bought a battery for it as it didn't come with one. My issue is, the battery worked fine the first couple times I used it, but now it drains instantly if I unplug from the wall. After I restart the machine, the battery says 0% (charging), and after a short while (10+ minutes) returns to claiming fully charged (100%). So far, I have updated the bios, installed the lenovo power management software, installed the lenovo power management driver, tried removing the microsoft acpi driver without the battery in, then turning off and trying to start on battery  (no luck turns off immediately as well, critical low battery error). I also did this thing someone recommended for battery trouble where you shut down the computer and remove the power sources, then hold down the power button for a minute. The battery health is good, it has had three charge cycles, and this number isn't going up with my little drop downs to 0% and back up to 100% whenever I unplug the machine. I would like help in figuring out if this is a problem with the battery, hardware, or software of the computer. I am running windows 7 pro 64 SP1. i7-3520M @2.9ghz. Thanks in advance!  Ryan

A:t430s battery charge issue

Hi and welcome, moreryanIs the battery Lenovo genuine, has Lenovo FRU p/n?Have you get it from the Lenovo related store?Could you make a snapshot of the battery surface labels with quality enough to recognize labels, symbols? As you can't publish images here, in the post yet, provide an external link. Also, as your OS is win7 and I hope Lenovo Power Manager application is installed, what are the values of the second half of the battery parameters (manufacturer name and followed) PM shows in the Battery tab? Make a snapshot as well.Answers and images are needed to understand whether the battery is faked since the battery for T430 should have HW authentication.

I have mostly used the Lenovo T series laptops.  At times I would have to unplug the power cord, pull the battery and push down on the power button to discharge power.  When lenoved came out wid models like the T480s that had a built in battery, they added a pin hole on the bottom that would simulate pulling the battery.  I can not locate any pinholes on the Lenovo L580.  Is there a way to discharge the power or simulate pulling that battery on this model?

Just received my new notebook and am extremely happy with it, execept for the battery indicator. The effective charge reamining, fluctuates by a wide margin, suddenly jumping from 4 hours remaining - to 3 hours - to 6 hours in a matter of minutes! The PC was left in idle state with no processing happening whatsoever. at 100% charge it shows 5 hours 6 mts of remaining time, as the charge drops to 97% after 5 mins of idle, the remaining time changes to 2 hrs 34 mins and at 94% charge after another 5 mins, it shows 7 hr 20 mins of remianing time! I called Lenovo service and after one hour of trying this and and that, they offered to replace the PC with a comment that battery takes 1 week to settle down and stabilise! I find that a bit out of the ordinary. My config is 710S, i5, 8GB RAM, 256GB SSD, Windows 10, with Lenovo optimiser loaded. (The battery gauge reset, suggested by service is missing in this version - the service staff themselves could not find it).  Is anyone else having similar issues?

Is it really advisable to let the battery in my laptop completely discharge occasionally? A lot of people seem to say this and I don't see anything in the owner's manual about it.
 

A:discharge laptop battery?

not just occasionally... you should allow it to fully discharge every time. this is not always possible, but try to as much as you can. rechargeable batteries will hold a longer lasting charge if it goes through a full discharge cycle first.

All rechargeble batteries have a lfe span which is measured by the amount of times that it can be recharged. so naturally if you allow a battery to discharge fully before recharging it, then you reduce the number of times that it is being recharged thus extending it's usable life span.

that being said, leaving a laptop plugged in all the time will kill your battery much faster thn it should because while it will not overcharge your battery, it will keep on recharging it when it loses a little bit of power (and yes, batteries will drain even if you're not using it)

speaking from personal experience with my trusty old Dell Insipron 8000 (don't laugh.. this thing was top of the line 6 years ago and it still works good to this day )... i used to buy a battery for it each year, but after the 2nd battery died, i stopped leaving it plugged in and I let it discharge each time before charging, I'm on the 3rd battery now... the first 2 lasted a year each. but the battery i have now has lasted 4 years and still holds a 2 hour charge. (if I used my laptop every day, which i don't, then it would not last 4 years. but because I allow the battery to go thru full charge and discharge cycles it will still hold a good charge ev...

So, my issue that ive looked everywhere for a solution to is this.  I was about to give this laptop to someone and I reformatted the hard drive to clean it up before doing so.  After this I went to dells site and loaded up the drivers for this machine.  All is fine up till this point.  Then I updated the bios to the newest version a12, and all went fine.

Well, later that day I needed to unplug the laptop and go to a different room and It just turned off after I unplugged it.  It wouldnt turn on with battery power either.  Plugged it back in and it loads fine but the battery is stuck on 36 percent charge and says not charging.  Now im getting a message saying the battery needs to be replaced as well, which is *** because I know that the battery was working just fine before this day.  Not only that why wont a battery with 36 percent charge turn on the laptop?  Its got the flashing red battery symbol when powered on with the ac adapter but without the computer on, but still plugged in, the battery doesnt charge or have any lights. 

I have already tried the uninstalling of the acpi trick, as well as the taking the battery out while its running, or taking it out purging the power and reseating.  Ive tried all the common tricks to no avail.  Not sure whats going on but I know this battery was good, and it still says 36 percent but wont charge and wont power the laptop on.  Hope someone can help.

Thanks Gary

A:DELL VOSTRO 3500 BATTERY ISSUE (not charging and wont power on computer with charge) HELP!

First check:  make sure the BIOS (F2 at powerup) recognizes the AC adapter.  If it does not, the battery will not charge. 
If the AC adapter is not recognized, try another Dell OEM adapter.  If that doesn't solve the problem, replace the DC jack:
http://www.parts-people.com/index.php?action=item&id=9935
And if that doesn't solve the problem, replace the mainboard.
If the AC adapter IS recognized, but the battery will not charge, unplug the system, remove the battery and hold the power button for 30 sec.  Try again -- if the battery still won't charge, odds are the battery itself is bad.
If the battery is original to the system, it's about four years old - well past its expected lifespan.

A:Internal hard disk drive not found after battery discharge

Faulty HDD Controller but I would have that laptop check out if you can. Most likely it's the MOBO that is to blame. MOBO = Motherboard. See if that was XP not seeing the HDD then you could re-install XP. But you said your BIOS is not seeing the HDD. It could also be your HDD as failed. Normally DELL has a tool that you run to test your system out. This tool is use by DELL Certified Techs to see where your issue is. HDD, MOBO, Battery. Most of the time the MOBO is replaced. Then HDD then the Battery to solve your issue.

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!

I have changed two batteries since I purchased my Laptop. I bought it 15 months back.
So, I have been going through the things that make my laptop batteries' life short.
After Reading many articles about batteries, I have made some inferences:
1) Internal stress inside the battery will be at peak, when it is Fully charged. Actually keeping it plugged in for long time causes, temperature increase inside the battery and life is reduced.
2) Never bring the battery to discharge fully or below 30%.
3) Plug out the battery when gaming. Keep the battery exposed to lesser than 40 degree celcius.
4) Discharging the battery at higher rate reduce battery life.

SO, Here is what i am doing. I pull out battery while gaming. I never charge more than 85%.
Also need some suggestions from you to increase the battery life.

A possible cause is purchasing "cheap" batteries, which may or may not apply in your case; they can also be a source of extreme overheating which can cause damage to internal parts. The last part is just an FYI.

I fear that this will, if it hasnt already done so, mess up my electric circuits among other components. Can any of you suggest or recommend options I can use to diagnose the situation. I would like to find out what the problem is, whether I should buy a new battery or some component or prong that I need to replace? Thanks for the feed back!

A:Battery will not charge or hold charge?!?!

Yup, sounds like a battery problem.

First, make sure the battery has a charge. Most laptop batteries have a button on them somewhere you can push that will give you the power level. Alternativly, there should be a utility in windows or the BIOS that will allow you to check the power level.

If the battery has no charge and isn't charging, then replace it with a known good one and see if it will charge up when the laptop is plugged in.

If the good battery won't charge up, then there is a problem with your motherboard.

If the battery has charge but won't power the system, then there is a problem with your motherboard too.

If this is the case, then the best you can do is contact the laptop manufacturer and get them to replace the motherboard.

I have an XPS 9550 6th Gen running Windows 10 (Just over 1 year, out of warranty).
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?
I would also like to disable the battery instead of having to open it up to disconnect, is this possible?

This is a bizarre problem I think.  My Lenovo P50 laptop will charge when turned off and plugged in.  But when I turn it on, it's running just off battery and therefore discharges rather rapidly (1-2 hours).  It does NOT say "Plugged in but not charging". It just shows that it's running off battery.  Additionally, there is no light on where plug goes in.  If I power down, sure enough light comes on and if I leave it for a few hours and boot up, it's back to 100%.  But then of course, it slowly discharges.   What the heck is going on? Thanks,Dave

Check to make sure your laptop is not in Airplane mode, because that would cause that behavior.     Check in two places, one under Windows 10's Action center (Icon to the right of Time in taskbar) and using Lenovo Vantage.     It could also be set in Lenovo Settings if you have that installed as well.  Lenovo Vantagehttps://vantage.lenovo.com/  Edit:    would uncheck "Enable auto detection" as well. Cheers,

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.

I have had my y580 since September of 2012 and for the first time I performed a full battery gauge reset yesterday because I was noticing performance loss (as expected over long use of battery). Once my laptop fully discharged, at first it would not turn back on for about 5-10minutes before I pulled the battery and put it back in. From there, turned on the laptop, the battery charged to the maximum capcity and after that, the battery would no longer charge.Currently, I just have my charger plugged in without a battery. Did anyone else have similar problems? Help!

Hello.
I've been using a Dell inspiron 1545 from about 3 years now and exactly after 2 years of my buy, the battery failed and it started showing me to replace the battery and always notified me about contacting dell for a new battery.
I didn't take this of much concern so i just ignored the message and kept on using my battery with my adapter plugged in. After 4-5 months of such usage, My battery completely failed and doesn't even offer me even a minute of backup, when i remove the power socket. Then i realized the importance of a new battery and then bought a new battery from Dell.
Its the same battery with the same specs and also the same family type. After i removed my defected battery, I replaced my new bought Dell battery and realized that my battery is working fine. its charging well but at some time, it says "Plugged in, But not charging" Which is rare for any new battery, which is bought brand new.

This is how it looks now after i remove the AC adapter plug and when i depend on the battery backup. it is providing me a backup, but I see a yellow exclamatory mark beside it. Which I think should not be present. it also says "Low battery" when there's already 99% of battery left!
I've also followed some online steps
1) updated by BIOS to the latest  2) Followed some other steps like uninstalling the battery ACI in the device manager and etc...
i would love to get this problem solved. I'm using a PA-12 family adapt... Read more

A:Bought a new dell battery and still my laptop battery doesn't charge!

Hi Utkarsh. I Actually FIXED this problem months back. and I exactly want to help you on this so that you can fix it yourself too..
the problem which is creating your battery to show an exclamatory mark is your power settings.
so follow these steps to get rid of that sign and a perfectly working battery.
1) Click on your battery icon (left click) you should see an option called " More power options" at the bottom of the popup.
click "More power options"
2) Now you will be taken to your control panel where you can see all of your power plans and under each plan, you will see an option called "Change plan settings"
3) Click on "Change plan settings" for your active power plan. Now you will get redirected to another control panel window, where you can see two kind of power options to get adjusted. that is, when you battery is plugged and when your battery is unplugged.
4) Don't touch those options, just click on "Change advanced power settings" at the bottom left of that window. THIS IS THE AREA WHERE WE NEED TO FIX!
5)After you click on "Change advanced power setttings", you will see a POWER options popup, go to the bottom and then you can see something called "Battery" with a plus sign on the left. click it.
6) Now you just have to change the levels for the following values
                   --> Critical battery level ( you can change it to 10%)

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................
 

A:compaq M2105 laptop - battery will not charge, flickers from AC/battery

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?
