It looks like the problem is pretty the same as with "Ideapad Z400 or Z500 battery will not charge - plugged in not charging". My battery worked fine when the OS was Vista , Windows 8, but after windows 8.1 installation it was "plugged but no charging". I already have reinstalled the windows, nothing happened. I tried to install the same firmware as Z500, but it isn't work. Lenovo Solution Center displays battery as "Battery software not installed". Downloading and running Settings Dependency Package does not help. I can't find a new firmware in any place
By the way, I checked my windows version, and it appears Windows 8 Pro (like it was before I tried to upgrade to win 8.1)
Solved! Go to Solution.

Welcome to Lenovo Community Forums!
I’m sorry to hear that you are facing battery issues in your Lenovo ThinkPad SL500.
I would suggest you to follow the below troubleshooting steps.
Go to control panel -> Device manager. Under batteries tab, uninstall Microsoft ACPI Compliant control method battery, restart the system and check if battery charges properly.
If the above said didn’t help, shutdown, unplug AC and remove battery. Press and hold power button for several seconds. Then re-install battery and AC, restart and see.
Update BIOS to the latest level.
Please post back with the results!

Mithun, thanks. It doesn't work
Microsoft ACPI Compliant control method battery uninstall - not affects anything
Pressing power button with disconnected AC and battery, also doesn't help
BIOS - I'm really have an old one, but I cannot update because BIOS Update requires 100% charged buttery although AC power connected
One little thing I didn't mention - when I'm plugging in an AC power, buttery indication in front on the laptop blinking once with orange color and turns off. It stays turned off always...

Is system working fine when connected only to AC adapter?
Can you swap and check with a good known battery and AC adapter?
To check if it’s a windows false alert, try to boot using a Linux live cd(no need of installing) and check if issue persists in Linux too.

Ok, the system is working fine with AC adapter.
I'm not sure weither any of my friend has this kind of battery
I've boot from CrunchBang Linux Live CD and it seems to recognized my battery. It displays the following details:
Technology: Lithium ion
Energy Full Design: 0.0Wh
Energy full: 0.0Wh
Energy Empty: 0.0Wh
Tooltip that opens over battery symbol in status line displays: adaptor is online. Your battery is charging (0%).
for last about half of hour it stays on 0%...
So it's to be seemed I need a new battery (this one an original one I bought with leptop about 7 year ago....)?

Capacity of a battery declines as the battery ages, with the number of charge cycles and time at high temperature. Under average usage patterns your battery maintains approximately 70% of its power capacity after the first year of operation.
I guess seven years is really a big time for a battery and probably it’s time to get it changed.

After I've changed the battery to a new one, it started to work. I still have windows messages about "not found software" for power management for this battery, but, who cares when it works...

I think it’s probably a false indication which you can neglect since the battery is working perfectly fine. Nice to hear that your issue got fixed. Please feel free to post back in Lenovo Community Forums if you have any further query.
