This problem appears to be common with this series of Acer tablets.
It is now nearly impossible to turn on the tablet.
When it finally does turn on after a short period of time the screen flickers and then the unit shuts down.
I bought this tablet about 2 years ago and I have been quite pleased with the value received for my money.
However, the charging issue has been annoying.
The tablet stopped charging about 6 months ago.
For some reason now, even when the tablet is plugged into the wall, it still does not function.
The unit has also recently been stuck on the Acer loading page and then sometimes it moves
to the battery charging page, though it then never charges.
Any ideas?
