I own an Acer Aspire 5810T (Windows 7)
Not the greatest laptop, but does the job.
The battery had the potential last for 6 hours due to the low energy consuming components in the laptop (I think). One day it just stopped working, when I plugged out my laptop to move it...the laptop shut off entirely. Basically, I have to keep it plugged in, in order to use it (which is very annoying).
It's nothing to do with the charger, as I've tested it out with another one.
I took a screen shot as you can see below, it stays at 48% and doesn't increase or decrease.
I am thinking of using the "Freeze revive" technique on the battery but I am wondering....is it possibly something to do with the motherboard or something? that the battery is actually completely fine? this is the extent of my knowledge by the way.
I have also removed the battery and just left it plugged in and it works fine without the battery.
If anyone can advise any troubleshooting techniques I would be grateful.
