A really annoying and almost Weihnachtsversauender point is that simply was our battery not initially present. I mean, he would not be activated, or load and was also not recognized. Here you had about the Acer Forum for the problem, which many users are looking for.
With the result that a BIOS update, with us 1.01 had to be carried out in 1:07. With the firmware update, there is simultaneously a Battery Update which activates the battery, thus the charging status displays correctly.
Now that we have tried a total of 3-4 hours all things now seems finally the battery problem to be resolved after we almost wanted to send it back.
This review should therefore serve as an indication to solve the battery problem.
It should also be Acer recommended to educate end users about the battery problem and somehow enclose seen immediately with the packaging.
Otherwise, as far as everything works without problems and thus you can give 4 stars.
