Thanks for your quick replies. I contacted support, and they were really fast to get back to me, but it rather seems a hardware issue. Battery connectitivity issues would have been a good idea, but the problem persists if i just take off the battery and try to run the edge straight from the power plug.
@aidren
How do you go to sleep mode and come back out of it? just with the menu button?
Another question (as i didn't have the edge on long enough to notice) is there any sound from the fan coming out from the machine, if it's normally on?
