I have this Laptop for something like 3 years and i'm having some problems about it... It's disconnecting from the charger randomly, actually not that random, it disconnects almost every time that i change to a High Performance profile, sometimes it disconnects just if i run something heavy and sometimes only need to be turned on to start disconnecting of the charger.
Don't think the problem is the battery or the charger itself.
