Preferred Solution: battery suddenly drained from 60% to 6%

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)



I own a Dell Studio 15 laptop, usually I get about 3 1/2 to 4 hours of battery life on powersaver mode, depending on what I have turned on and stuff. But when i checked my battery a day ago, I only had 1 hour and 45 minutes of battery life at 100%!! I know that battery life drains over time, but this was so sudden! I lost 2 hours of battery life overnight! Could anyone explain what has happened and how I could go about fixing this problem?

Thanks a bunch!

 My G700 has had this issue recognizing its own OEM battery since I got it, and there is a long drawn out way of trying to resolve this, but the core problem I believe is that when the battery is Fully Drained it can't Self Identify as an OEM battery, so the laptop won't charge it.  Without charge, it will never get out of this state. Problem:  Battery not recognized correctly as OEM, so won't chargeFix:  Charge battery at least a little bit Yes, I know it won't charge, so how do you perform fix? Plug into power and take battery in and out 5-10 times, leave battery in and remove and replug power cord in side of laptop 5-10 times.  Then leave for 15 minutes, then boot normally. Battery will now be recognized!  Why because you managed to get just enough juice in there while trying to identify the battery 10x or so, for the battery to be able to successfully identify itself when you did start it up. This is a HACK fix, but way better than uninstalling, reinstalling power software, BIOS software and device drivers a number of times (which does not work all that well, I have found). Hope this helps you, let me know! OHHH, and keep your battery charged at least a little to prevent this from happening, and turn power off when not using.  I am not sure if this is just some faulty batteries or all batteries, let me know if other batteries behave better than mine. Best,Mark Eckdahl

Hello there,
I have a Dell Inspiron 3542 and for the past few weeks I have found that the battery drains after shutting down the laptop. The following is a step by step explanation of the issue :
1. After charging the laptop to 100 %, I clicked Start > Power > Shut down.
2. After waiting for like 5 minutes and ensuring that the laptop is, like "dead" ( no sounds, vibrations or anything ), I closed the lid and kept it on the table.
3. Next day, switch the laptop on and it does not turn on. The battery light flashes for a second and goes off. I connect the AC adapter and the laptop switches on. It shows 0 % battery.
I have run a full diagnostic check up of the laptop and the results do not display any issues related to memory, hard disk or the battery. Lid sensor also works perfectly.
However, I found something interesting. I checked the Event Viewer and I found the following logs :
1. Information 10-09-2017 21:16:51 User32 1074 None :

I've a problem with my Z930-164 : The battery loose around 8% every 12 hours while it is off.

I've the latest bios (6.80) and the latests drivers. I'm with windows 7 64 bits.

By trying many things, I've founded that it is the option : "Sleep and Charge" in the bios. By default it is on Auto mode (1.5 A), there is a 2.0A mode too. If I turn it off, the battery only loose 1% every 12 hours while it is off.

In default mode, why it does not power the USB while sleeping ONLY if there is a device ? Not to drain the battery !

It is a huge problem no ?


A:Satellite Z930 : Battery is drained while off

The enabled Sleep & Charge function affects the battery working time.
Sleep & Charge allows to charge external connected devices (like smartphone) even if the notebook is in sleep mode.

Furthermore enabled ?Wakeup? options (Wake up on LAN, etc..) which are available in BIOS would lead to battery discharging.
Therefore disable these options if you don?t want to discharge the battery.

As title suggests - is it better to drain a battery then store it?

I.e. I have a spare laptop battery....


A:Best to store a spare battery drained?

hi there

If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

I left my T400 on overnight running on battery (clearly not the brightest idea), and now it won't start up.  The plug and battery lights do illuminate when I plug it into an outlet; when I turn it on, the num lock and caps lock lights illuminate briefly, and the power status indicator light illuminates.  It makes a few whirring noises, and then just sits there.  Does anyone have any suggestions for troubleshooting this?  Thank you!

This first time it occurred when I was browsing websites for a school project. The laptop suddenly turned off. I did hard reset by holding the power button and everything but it won't turn on. The backlight key and fan still working but the screen is black.I let the laptop there for some hours. Then it was able to turn on normally. I then charged the laptop to 90% and turned it off. This time the problem occurred again. It won't turn on correctly unless the battery is completely drained !!! I contacted Microsoft and they had me reset my laptop, but the problem still occurs! I've tested many times !!!I was frustrated so I took the battery off with some screwdrivers. So now I only use the AC adapter. However, the freaking thing still happen! I can't identify what is the problem !! I need help !

The lap top has been working with no issues since purchase, but last week it was being used and the battery was completely drained and it switched off. As it was not needed at that point, it was left until the following morning. When it was plugged in, it woudl not start. So we left it charging and still nothing. When you push the start button the keyboard lights up for a few seconds and then goes off and that is it. I have read through numerous other similiar issues and have tried all of the following with no success: 1. Pushed and held power button for times ranging from 20 seconds to 1 minute2. Tried reset button3. Opened up back and pulled plug out of battery, then tried various combinations of pushing power for extended periods, with no power cable etc, and then plugging back in again So now at a bit of a loss as tried everything I can read on line with people suggest, the only other but I have read is about removing RAM, but not sure where they, I think below the battery. So not sure if I need to completely remove the battery etc, but wanted to see if anyone else had any better / easier ideas before I try that. Thanks for any help and guidance Model number - Lenovo Yoga 2 13, Model name 20344

I have an old Dell Inspiron 2200 laptop running Windows Vista Home Premium 32bit, and I recently replaced the battery that originally came with it.

The new battery is good, it lasts about 4 hours on a charge, but Vista seems to be reacting to it very strangely. Immediately after I take it off AC power, Vista will alert me that my battery power has reached 99% and is critically low.

After that it'll run fine for about an hour, then when it hits 75% or so it will put itself into sleep mode automatically as if the battery was dead. After it's asleep, I can turn it right back on and it will run for an additional 3 hours before shutting down again (this time because the battery really is dead).

I've tried full-discharging the battery to calibrate it a couple of times, but it made no difference in the behavior. As far as I can tell the battery is fine otherwise (the percentage and time remaining that Vista tells me seem to be accurate), and the computer has no problems when it is plugged in to AC power.

This strange behavior happens exactly the same way every single time I run the computer on battery. Low Battery warning at 99% and false shutdown around 75%. After that it's fine. Any ideas what could be causing this problem?

Hello Chefgon, and welcome to Vista Forums.

Double check your advanced Power Plan Options (Control Panel) settings under the Battery options for what levels it should warn you at. You can adjust these settings for what it should do when it reaches the level you set.

When I do a suspend to ram during the night, battery can lost 20%... don't think is really normal.

How much charge do you lost during the night?


A:Satellite Z830 - Suspend to RAM -> battery drained

Even when notebook is OFF battery will lose the capacity so it is ?normal?.
How many percent will battery lose is different and not the same on all notebook models.

To be honest if you use notebook on battery power supply it is logic to me that during the night you use hibernation and not stand-by mode. Stand-by mode is for short period of time only.

I have received my new X260 laptop a month ago (also my first Lenovo), I did a fresh install of Windows 10 Pro and a bunch of drivers. It has been working well until now. Two days ago, I used it all-day with original adaptor plugged in. At the end of the day, I unplugged it and close the lid to put it to Sleep mode before I left work. The day after, I came to work and found my X260 battery was at 5%. I thought I have mistakenly set the Power Option so I checked and it was set to Sleep when I close the lid. Yesterday, I did the same, put it to Sleep before leaving work, but this time I clicked Start > Power icon > Sleep to make sure it entered Sleep mode and I watched the red LED on the lid blink slowly. Today I came to work and the battery was at 5% again! I am suspecting that X260 woke up at some point during the night. I don't know how, no cables connected. Please guide me if I need to update any driver or check any settings on Windows/BIOS. Thank you.

I looked at the Event Viewer and it appears it entered sleep, and then resumed from sleep two seconds later (I'm guessing right after I shut the lid).  How do I stop this? I have the power options to "sleep" I have tried to turn off all the "Allow this device to wake up th computer" - no matter what I try, it seems to not go to sleep. It does *sometimes* but the vast majority, it doesn't if I just shut the lid.  My BIOS is updated.  Is there any lesser known fix?  EDIT: Oh yeah, and sometimes it won't wake up from sleep when pressing power, or opening lid, or pressing fn + 4.

Dear forum users,
I have a big problem as my Dell Inspiron15 3000 series laptp started to behave strangely since I updated the bios from the version on the dell drivers and support website. 

I upgraded to the V12 version Dell Inspiron 3442,3542,5748 System BIOS Version: A12 ,A12, when originally the laptop came with version A06. 

However, since the upgrade, my laptop battery drains after I have switched the laptop off. Therefore I'm having all kinds of issues starting the laptop in the morning and I am afraind this behaviour will lead to a disfunctioning laptop rather soon.
Downgrading the bios version to version A06 is not possible as the utility exists with the message that Dell doesn't recommend downgrading the BIOS version.
What can I do?

Hello, Welcome! Thank you for posting in the HP Support forum. Despite the fact that the battery power drained during recovery, I suspect the recovery partition is still there and intact. You just have to restart the recovery process. Here is how: 1. Please, shutdown the computer using the power button2. Power it on.2.1 As soon as you press the power-on button, imeediately start hitting the Esc button (like tap-tap-tap).This should open a HP Startup Menu which may look similar to this one 3. Choose F11 for System Recovery options.The computer should boot from recovery partition to open you various recovery options. Note, that F11 option will only work if the recovery partition is there (not deleted) and intact. From there, you have prenty of options to choose from. Follow the on-screen instructions .

I have the following big problem with my Satellite Click Mini L9W-B - this happened already two times.

I suspect that this may be connected to some Windows 8.1 setting. It also may be it is BIOS related.

PROBLEM: if I leave the laptop in a sleep mode (by just closing the lid), then If I do not use it for some time (>10 hours) then after that I could not switch the laptop on - it simply does not respond to any keys including the power on button. It does not matter whether I connect the power or disconnect it, I still can not power on the laptop, also it does not matter whether I try it with or without the keyboard attached. BUT: the battery on back on the screen is warm ,so obviously the laptop has not been switched off completely and something (i.e. windows sleep mode or bios or something else) is preventing me to power it on.

The solution I have so far is to leave the laptop for a very long time disconnected (to drain the battery completely - it will not be warm any more!) and then connect the power and then it will be able to switch on. Alternatively, opening the screen cover and manually disconnecting the battery and then connecting it again also work. After that the laptop can be switched on and works fine.

Obviously it is not very good because to wait very long (several days!) or to open the cover is not really a good option when you need the laptop!

Can you help?

May be it is something to do with some power-saving features of Windows?

Many thanks!

A:Satellite Click Mini L9W-B - could not switch it on until battery is fully drained

There is a quick workaround instead of waiting for the battery to drain...

Hold down power button for around 20-30 seconds. That should hardware turn off the power completely allowing you to turn it on again.

Update the bios to the latest version and apply all windows updates after that, that may solve the sleep bug issue

A:win10 battery drained so fast unexpectedly, Dell Inspiron 15-5559

Turn off Fast Startup. Under Windows 10, your computer does not totally shut down with Fast Startup on. It can actually be running processes when you think it is "shut down". If you leave it off AC power for any length of time, it can drain your battery. With Fast Startup off, your computer will boot slightly slower, but it should not make a big difference.

I have a Dell 7737 laptop and from time to time it develops a firmware glitch where random keys stop working for both BIOS Setup and Operating Systems. After such thing happens neither shutdown (Full shutdown / Fast Boot disabled) nor restart get the keyboard back to a normal state. At this point the only workarround is to disconnect the AC power cord and then either drain the battery or physically remove it.
This laptop's battery cover is not designed for daily removal and it is starting to get loose because of this BIOS bug.
I am running BIOS version A14 but this bug was present since I purchased the laptop with BIOS version A07. Sometimes I cannot even type my password because the random keys that stop working match those it uses.
Please Dell could you provide a BIOS hotfix for this annoying issue?

Hello,  I recently bought a replacement battery for my T530, upgrading from the 6-cell to the 9-cell version. While I did not buy it from Lenovo, I bought it on ebay, the seller had very high ratings, and as far as I could tell it is genuine. It worked wonderfully for a few weeks, however yesterday upon boot-up I received the "Battery is not supported by this system and will not charge" error.  I don't understand how it could possibly be a counterfeit battery if it's worked fine up until now. I would really appreciate any ideas! Thanks!

This makes me sad. I installed Win 7 when it was first offered, I absolutely loved it compared to Vista and XP. Now, though, a mere 4 months later I am having alot of problems. More so than I had with Vista. It now takes minutes to boot up, my peripherals randomly stop working (I have to remove and reinstall my MS Bluetooth mouse about every 30mins. No kidding), the computer just shuts down for no reason (which it has suddenly stopped doing) and putting it to sleep causes all kinds of frustration when I try to wake it up. Then, I noticed my battery was draining in about 45mins.

So I looked into it and it seems the battery issue is not totally uncommon. Then I read that MS is saying it is not the OS but our batteries. As I've written this my battery has gone from 50%-35%-28%


Here is the point where I say I am moving to Mac- blah, blah, blah ( I am this time I swear it, no really, as soon as I can pull $2k out my arse)

Any suggestions? I am going to reinstall the OS which I did annually with Vista anyway but hoped to not have to do with 7. Anything?
Sorry to bitch but I am so tired of being frustrated with my PC's.

When my T410 is on AC power,  it meter shows the battery fully charged.  But: When I boot it on the battery, it immediately shows "0190: Critical low battery error" and shuts down. When I unplug it from AC power while it's up and running, it stays alive for a minute or two (still showing the battery to be charged), then dies with the same message.The machine is several years old, but the battery is only one year old.  The machine Type is 2537-22U. I read the post on this forum that suggests updating the firmware (https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/ThinkPad-Battery-Firmware-Update-fix-a-l...), but the link to get the firmware update doesn't seem to offer any for the T410. Is this fixable, or is this machine a dead duck? ~ Thanks in advance for your help!~ Ken 

A:T410 suddenly won't run on battery

I don't think that your machine is a dead duck...the battery perhaps, but not the laptop itself.   You could update the BIOS if it is not current, but you need to be very careful in doing so, because if you were to lose AC power during the update with a weak battery, you could leave the system unusable.     I suspect that you probably need a new battery.   I do not know what brand of battery you bought before, but the price and quality of of aftermarket batteries varies greatly.   From my experience, the cheaper batteries found on ebay etc. never last very long, because usually they are from old warehouse stock that have been in storage so long they have already deteriorated to some degree, and/or are built with inferior Lithium battery cells.     If you travel a lot and/or need a a battery that lasts, you can buy a genuine Lenovo brand battery from Lenovo via Encompass parts for $55 bucks (6 cell) or  $73 bucks (9 cell) (both are on back order) or you can pay around $100 bucks for a 6-cell, or $110 bucks for a 9-cell at places like Batteries Plus.     Fortunately the batteries on that model can be easily replaced, unlike some of the new models that require you do take the laptop apart.   Cheers, ThinkPad T410 and T410i Hardware Maintenance Manual (possible battery part numbers start on page 154)https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pd...

The LED is orange and blinks.If you need other details feel free to ask.EDIT: Latest BIOS installed, Windows is updated, there is no "USB Always on" option in the BIOS.?

Hello, first I apologize, if my post will have grammars errors, english is not my native language.Well - I have an IdeaPad 700 since a half year. On Monday I noticed, that the time for how long my notebook can run on battery dropped from about 4 to 2 hours. Plus I experience from the same moment some display blinking now and then (it blinks 3x times a day - for a second there is a black screen). I looked up the battery capacity in Lenovo Settings and it says, that there is 39 Wh form 45 left...which doesnt sound for me, like it should cut the time to a half. I did a malware scan, i looked in my power plan and in the battery consumpting Software and I found nothing suspicious...One think is strange - when the battery goes to ca. 30% the remaining time starts to improve. Like in was 1:15 time remaining when on 60%, when it goes to 30% i get 1:30 ??? Im starting to think, that it has something to do with the last big Windows update, that happened on September 30. but im not sure, if i wouldnt not notice the problem earlier. Or is my battery just bad?Thanks for answers.

Hello guys and girls,

I have an issue since some times that I really don't know how to solve.
In November 2013 I bought in Poland, where I live, a nice TOSHIBA SATELLITE L50-A-16Q (PSKJNE).
On this computer, although, something is constantly causing me problems: *very often the power shuts down suddenly while on battery*, even if the app "TOSHIBA PC health monitor" which also monitors CPU temperature, does not show any sign of criticality.

However, there is something abnormal going on: I have noticed thanks to this software that, every time I unplug the charger, the fan speed goes to zero, apparently putting the system cooling at risk. And I know from the manual that if the processor temperature reaches a critical level, the system automatically shuts down.

Is there anyway to fix the problem in order not to shut it down suddenly, making me lose data while on battery?
Maybe turning on fan speed, somehow, while on this mode?

Thank you every one very much for your contribution, in advance.

Kind Regards,

Hi Matteo

On this virtual way it is not easy to say what is wrong there. It would be interesting to know exact battery capacity when this happen.

Using advanced power options you can change many important values so I recommend you to test all this. Try to use notebook with power saver power plan and lower CPU activity.
I don't know if the CPU or any other hardware component reach critical temperature level but please be careful how do you use your machine. Cooling fans must be free and your notebook must be able to ?take a breath?.

Try to test usage with different power plans and using it on the desk only, not placed on the knees or your bed.

By the way: cooling fan activity can be defined in advanced power settings > Toshiba power saver > cooling method. Check it out.

I have a U430 Touch and suddenly it's giving me he message "Your battery is damaged and needs to be replaced." The battery meter says it's fully charged. On top of this, I think there isn't a good contact for the power adapter and if I move my laptop, it turns off. Has anyone seen this happen? I assume I'll need to replace the battery (joy) but it seems odd since I haven't had battery issues until now.
Mod's Edit: System model added to the front of Subject line to improve visibility / clarity.

My y50-70 was working normally with no problem for almost 2 years.. I always use conservation mode when the charger is connected..Today I was working as normal on my laptop and suddenly the screen turned black and the laptop shutdown but the power button is still lighting...I panicked.. so I tried to restart the laptop by long pressing on the power button.. and it restarted successfully.. only the battery is no longer recognized.. Windows says no battery installed.. Lenovo energy manager and solution center say that the battery is not installed.. 2 days ago I ran the usual tests in solution center and everything was working well including battery and charger.. also I was doing light work and the laptop didn't overheat at all.. Now my laptop won't start without the charger and the battery light doesn't illuminate .. some forums suggested that I reinsert the battery but it's internal.. some suggested BIOS reflash but the lenovo installer says "reinstall system battery" and won't continue.. I'm using the original charger and original battery.. all drivers are installed from Lenovo website.. I'm out of warranty and there are no replacement parts for my laptop in Egypt since it was discontinued.. please help.

Dear community,
My XPS battery used to work fine (~3-4 hours of battery life). Since yesterday, the battery does not last more than 1 hour! It is quite disturbing since I have not installed any new software, and I am always careful not to let the battery go under 5% (in order to avoid complete battery discharge which can be fatal).
Now I am unable to use my laptop during a conference/meeting if I cannot plug it in. This is very annoying as I am often traveling for my job.
I have tried with both Windows 8.1 and Linux: with both systems, the battery does not last more than one hour. I have also tried the Dell diagnostic tool but it does not detect any issue.
Any recommendation?

A:XPS 15, battery performances dropped suddenly

Which model XPS, and how old is it (and is the battery original)?  Bear in mind that 2-3 years is the normal lifespan of a battery -- if the system is of that age, you're likely seeing normal deterioration of the battery and the need to replace it.

Hi,I am noticing some crazy behavior on my T440P laptop battery.I used my laptop directly plugging in for 90% of the times and hardly used my laptop much.My battery used to work fine, but now, it is tuning off and the "Full Charged Capacity" is just dropping every reboot.I really do not know what is going on? Please see some logging details below.As you can see in the attached image, the battery goes from 31.7% to 100% and then while discharging it goes from 81.8% to 5.8%. Can someone please tell me whether this could be 1 faulty cell in the battery? Is there a way I can check?Could someone else have gone wrong? I even let the laptop die (below critical) to see whether Windows is reporting correct charge values, and the laptop actually died a few minutes after going to 0%.P.S: I was running a system load program to drain the battery and simulate the behavior.I even tried a battery guage reset twice, the "Full Charged Capacity" is just dropping since a couple of days now!!
