I'm trying your suggestions today . I have 7 days to return to seller. So if none of this works by this week, i will be exchanging for a different one. It will be another MS Surface 7 , lol.
When plugged in , I HAVE NO ISSUES! She wakes up from sleep with a mouse wiggle and if i am gone for an extended period of time will quickly startup from a short start button press. (Meaning : she didn't completely shutdown , lock up , or overheat.)
I'm not able to use my keyboard or arc mouse when unplugged , which isn't a HUGEEEE deal for me ( I take notes via pen .) However ,Writing a paper for school is another story ; the keyboard is way more efficient .
Aside from that my only other complaint is the onscreen keyboard appearing when i need it . I'm absolutely in love with this device besides , so i reallllly hope there is a fix for us all.
Ill try to keep you updated on my progress.
