Likebook Mars stuck on sleep screen
Hi, I bought the Mars about a year and a half ago, and regularly use it. There is no external SD card in it. Suddenly after a night's sleep the Mars cannot be woken up from the sleep screen, though it definitely has battery (because I use it practically everyday, I never let the battery go below thirty percent). I've tried long-pressing the power button for 1 minute, and charging the Mars, but none of it is waking it up. Any ideas what else I can try?
Thank you very much for the help!
