Precision 7510 _ Battery stops charging at 87% after full auto update
My Precision 7510's got a new battery for only a month. But after having had regular full update on 4th November, I notice that the battery stops charging at 87%. I've tried several methods of solving the problem but no method works. When I hover on the Battery icon, it only says :87% available (plugged in). I also keep the machine working for almost an hour but it neither gains nor loses any percent, still stands at 87%.
Anyone please, help me solve this problem. Thank you in advance !!
