2 and a half years ago I bought an Acer, Aspire 15, the F5-571-320G.
In the second year it started to only charge when sleeping or off. Once in a while I’d get it to charge even when on but chances of that happening have lowered with time to almost zero.
In the last six months it’s become hard to get it to charge even when it’s sleeping. At times I have to disconnect the connection by the power box, make a few light touches and hear a few sparks before it charges and sometimes it feels like certain wall sockets in the house help more than others. Sometimes it’s easy to get it charging sometimes not.
The battery is not what it used to be used to assure me of a few hours, now I’d be lucky to even get near 2 hours.
