Many moons ago - back in 2017 I think - I bought my wife an HP Pavilion. Or rather we bought it together for her.
For the most part, she’s liked it. She has had a couple of complaints - mainly that it seemed slow at times.
Most recently - and I’m impressed she noticed - she said her battery percentage was decreasing.
The thing is - the laptop is almost always plugged in. There’s no reason is should ever be that much less than 100%.
But despite being always plugged in, the percentage started to creep down. 75%. 50%. 25%.
It didn’t go down as fast as if it weren’t plugged in - this was over weeks and months.
So I ran the PowerShell command
powercfg /BATTERYREPORT and it generated the following HTML:
Yep - the battery was about dead. After all, it’s been five years.
I ordered a new one with as as much amp-hours as I can find - a NinjaBatt Pro Battery 2600mAh - and replaced her old one.
And her battery is now happily at 100% again.
