A few days ago I just used my S7-391-73534 with battery power for an hour. When I went home and plugged in the AC power, the battery sign showed "6% available (plugged in, charging)", while the battery charging sign was constant RED. However, the percentage of the battery power never went up but down to 5% after 1 day, and 4% now. I tried to press the battery reset button either short time (1s) or long time (3-5s, battery charing sign will turn blue from red, then back to red again), but there is not any improvement.
Normally battery lasting time will be reduced gradually over time, but not stop working suddenly.
This is only couple of months after warranty period. If this is the life span of the battery, Acer shall look into the design for more reasonable length of the the battery life span.
If not because of battery life span, what is the solution?
Thanks a lot.
