SOURCE: Battery is not charging

From HP website- worked immediately for me.
This document pertains to HP Notebook PCs with Windows Vista. Understanding battery charging issues If the notebook battery is not charging or the notebook does not indicate that the battery is charging, the most likely scenario is that the battery itself is operating correctly, but its power management software may have become corrupt. In order to correct the problem, you will need to uninstall and reinstall the power management software by using the Device Manager. This document will explain how to uninstall and reinstall the ACPI Battery listings in Windows Vista, as well as how to obtain and install updated BIOS files, if needed to correct other battery issues. Uninstalling and reinstalling power management software in Windows Vista In order to correct problems with the battery's power management software, follow the steps below.

  1. Click Start and type device in the search field, then select Device Manager .
  2. Expand the Batteries category.
  3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall . WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
  4. On the Device Manager taskbar, click Scan for hardware changes c01176420.gif . Alternately, select Action > Scan for hardware changes .
Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The notebook should now indicate that the battery is charging.

SOURCE: VAIO VGNTZ150N Laptop battery runs down when not in use

If the laptop is gone into a suspended mode it is still powered on but sleeping. This will continue to use power and will power down the battery over time.

You could enable hibernation which saves the current state of your pc so that when you activate it again it restores to your previous state of work. This will use close to no battery power to perform.

SOURCE: Lenovo 3000 N200 battery not charging.

I just had the same problem. My battery had discharged to less than zero and would not start even though the power plug was in. I tried everything... but what fixed it for me was to remove the power plug, remove the battery, plug in the power cord and start the machine. Once the machine was already booted, I put the battery in and it started charging. Dont know if that will fix your problem, but it fixed mine.

Take the battery out, with the power plugged in replace battery, orange battery level lights on the laptop will light probably stay on for a few seconds then go out. Repeat until battery level lights indicate a lower level usually one light. continue watching charge state ( the blue battery led on the lower left on the laptop should be blinking) once the battery gets a start charge it should continue to fully charge. Sometimes batteries drained too low don't have enough power to run their internal circuitry to start charging.

Re: Lenovo laptop, series 3000 Is 45% battery capacity sufficient to upgrade BIOS?


As long as you have a good power source from the mains, all will be fine but ensure your firewall is allowing the upgrade!

Lenovo Z500 battery


I did not work for me in the beginning because Z500 didn't know it had a battery.

1. First do a clean install of Windows 7.
2. Install all the drivers only for Lenovo site and respect the restarts. Install Lenovo Energy Management last. Go to Lenovo Energy Management and set it for full Performance.
3. The indicator in the animation should be far right not center.
4. Go to Advanced Power Settings in Control Panel -> Lenovo Energy Management and hit ENABLE
5. Now you restart and you should be able to do the firmware update

6. If you cannot do the firmware update then uninstall LEM, remove ACPI from Device Manager, Reinstall LEM, Enable again.
7. If you cannot do the firmware update then try battery gauge reset in Safe Mode and remove ACPI after, and then Reinstall LEM, Enable.

Lenovo battery won't charge


Battery not charging usually means its dying! If your battery under one year old, you can get replacement from Lenovo. If its older than three year old, its time to find a new battery!
Is the battery not holding the charge at all? that means is the computer shutting off as soon as taken from power outlet or battery lasting less than expected...

A sudden drop from 50% to 7% means that the battery is faulty, it is simply a case where it is not holding any charge. I would suggest you contact the seller and check if the battery is under warranty. Hope this helps and good luck.Any question please feel free to ask.

If your computer works directly to electricity without the battery, then the battery is faulty. Battery showing you 99% does not mean it is working, because bad battries gets full on time. The cell of the battery might have been dead because only GOD knows how long it had stayed in the factory.

But if you are convinced that the battery is good, then check the adaptor, and if the adapter is good.

Just try to check everything to ascertain the fault. And let me know what happens next.

I wish you the best.

Had a gateway laptop that had similar issues. 1. Has the unit ever overheated ? . if so you may have to open the case down to the battery, hopefully the unit has a plug in style battery, when you unplug it and wait 30seconds, then plug it back in you will reset the bios on the unit. I was about to junk my 6 month old computer until i tried this step. put it back together... every thing resumed as normal didnt lose or change a thing. hope this helps

Battery problem-plugged in, not charging. Lenovo 3000 N100.Type:0768.Model:24U.S.no:L3LA215. Please offer a solution.


Had the same problem with a manufactured refurb, would go to 79 %, if you go to power options, change plan settings, change advance power settings, then to the Lenovo energy management tab, press the big enable Lenovo energy management, click on the blue gear to the left of the question mark, if "Optimize for Battery lifespan" is selected it will only charge the battery to 80%, change this to "Optimize for Battery Runtime" and it will charge to 100%
