Windows xp battery meter not updating
If you're comfortable accessing your PC's BIOS, you might find a battery calibration tool within.This all depends on the laptop and manufacturer, so don't be alarmed if you can't find it.
There are registry keys BLOG : "" in All Users/Run. I think that the power guage and power icons disappeared when I was trying out a Boot Manager (Startup Guru) but I have also recently installed Kasperky Internet Security or the damage might also have been done by Registry Mechanic.
As you use your Windows 10 laptop, the battery goes through a number of charges and discharge cycles that slowly wear it down.
Calibration isn't for the dead battery sitting in storage; it's for a battery that still works properly, yet doesn't show an accurate reading when it comes to life remaining.
Before going through the hassle of charging and discharging your battery, we must first change the power settings to keep your laptop from sleeping or hibernating too soon.
This is intended to be a straight draw on the battery and letting it go into a power-saving mode will ruin the calibration.
