Re: Power Meter for Battery Life Not Working

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Sounds like a case for battery recalibration. Different makes of laptops
have different methods, but generally, you turn off all power saving
features whether it's in the BIOS or OS. Then you turn on the laptop and
leave it on until it drops stone dead. Since you've turned off the energy
savings features it won't shut down when it reaches some predetermined state
of charge. Then you fully charge the battery. Your power meter should give a
true reading now. (Never tried it myself.)

Look here under "Initialization and Calibration."
