Hi,
I have an Acer S3-391 laptop and was quite happy with it. When the Win 8.1 update came out I updated my system. Happy as can be, but then the misery started.
After using a week or so my battery stopped charging. My traybar battery icon now says 50% available (plugged in, not charging). It seems that my battery isn't holding any charge at all, as when I pull out the power adaptor my laptop just dies. Windows battery report shows that the battery is still in a recent condition.
I already tried to re-install the Microsoft ACPI-Compliant Control Method Battery.
All this happened just few weeks outside the warranty period. I now have an "ultra" desktop. Does anyone have the same experience?
