I've got this error on my T100TA,
I am using Speccy. The Graphic parts shows error.

And my battery is charging too slowly, around 5 hours from 30% to 100%, (as shown by the battery wizard)
Is it normal, or battery dead?

That being said, the T100HA is charging faster, about half the time, theoretically, is it using more electricity than TA or same amount?
