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):
Disable anti-virus software
Install Lenovo Settings Dependency package for Windows 8.1(no need to reboot when prompted)
Install Power Management Driver for Windows 8.1 (reboot if prompted).
Download Power Manager for Windows 7
- Run the downloaded
.exe file to extract files, which are stored, by default, at
- Manually set one by one on all
.exe files to run in Windows 7 compatible mode.
setup.exe to install power manager (reboot if prompted).
- Verify that installed .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).
- Now launch
pwmui.exe and everything works as before like in Windows 7.
Final note: when running
Battery Maintenance >
Battery Gauge Reset, be patient and set Windows 8.1's
power options to "Maximize Performance". Keep AC power attached and wait 3 hours or more until reset is completed. 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!
I have my X230 one year and a half. The battery suddenly stops holding power and appears losing capacity. 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. 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.
After pulling some hairs and a day trying, I finally got it working. Initially it showed my battery condition "poor" and holding only 10% of original capacity. Now it's in "good" condition and holds 99% of original.
