I have an Acer Aspire E 15 who is about 3 years old, I never dropped or damaged it in any significant way.
Since a month or so my laptop just dies at 70% whiteout any battery warning sign. To my relief it just seems to be an empty battery, plug it back in it restarts an everything is fine.
So i tried re calibrating my battery. But there is no option in the boot program and just changing the critical battery life to 0% in advanced battery settings and letting the battery go from 100 to when it drops out changes nothing.
I can however change the processor power management > maximum processor state. If i decrease this significantly 80% 50% 20% then the battery wil go lower to 65% 60% and 50%, But still no warnings before it just shuts down/ crashes.
How do I get a correct battery reading again?
If that's not possible or the battery(or some cells) are damaged then how do i get correct battery warnings back before it just drops out?
Thanks in advance!
