Sounds about right, since giving it a few full charges all the problems have disappeared. Now I just need to tell the retailer I don’t want to send it back any more.

Hope you are enjoying the machine?

The battery level showed always 100% (for like 5 hours).

Then I turned it off, plugged it to the charger and went to bed.
Today when I turned it on, it kept the 100% level indicator, but after half an hour it just died.

Turned it off again, plugged the charger, let it charge for a few minutes and the problem dissappeared. The battery status is working fine now.

My 2 cents: don’t trust the battery status indicator. At least until the first full-charge.
