This finally appears to have resolved my problem.Įverything I have read about the 'plugged in, not charging' problem suggests that there are many possible causes.

This then made me suspicious of the power extension cable I was using, so I plugged the laptop power cable directly into a wall socket. After unplugging and replugging all three connections, the laptop started charging again for about 30 seconds before reverting to not charging status. Like most laptops of my acquaintance, this Samsung has a standard two-section cable, with a 'brick' in the middle. Quite by chance, I chose to pay some attention to the power cable connections. Suggested solutions that involved unplugging the battery were not practical as Samsung has not designed this machine to have easy user access to the battery. Uninstalling the ACPI driver had no effect. I'm using a Windows 7 Samsung Chronos laptop rather than a Windows 8 Lenovo but this issue seems to affect a wide range of laptops. I had the same 'plugged in, not charging' problem earlier today. Now it's in "good" condition and holds 99% of original. Initially it showed my battery condition "poor" and holding only 10% of original capacity. Some suggests adding/editing Windows registry to set battery "start charging" and "stop charging" thresholds, which I did but didn't seem to help much.Īfter pulling some hairs and a day trying, I finally got it working. Remembering Lenovo used to have Power Manger which can calibrate/reset battery gauge, I searched Lenovo website and the Internet and found nothing nor real solution for Windows 8.1. The battery suddenly stops holding power and appears losing capacity. The status tells you it's doing discharging or charging, time remaining shown is not accurate and sometimes doesn't seem to be moving/changing, just be patient! Keep AC power attached and wait 3 hours or more until reset is completed. Now launch pwmui.exe and everything works as before like in Windows 7.įinal note: when running Battery Maintenance > Battery Gauge Reset, be patient and set Windows 8.1's.exe at C:\Program Files (x86)\ThinkPad\Utilities are all set to run in Windows 7 compatible mode (if not, set it each again manually). Run setup.exe to install power manager (reboot if prompted).exe files to run in Windows 7 compatible mode. exe file to extract files, which are stored, by default, at C:\DRIVERS\VISTA\PWRMGRV. Install Power Management Driver for Windows 8.1 (reboot if prompted). Install Lenovo Settings Dependency package for Windows 8.1(no need to reboot when prompted) I would like to share my verified working solution on ThinkPad X230, Windows 8.1 (and for those looking for ThinkPad Power Manager in Windows 8.1):
