So i got a surface. And i got problems. I am willing to solve these before reterning it, but i need som help. I start it up the first time, create a long profile name (my own name, 23 letter/signs, also counting the two spaces), and a password i have used before and remember. When I am about to log in the first time the/my profile-name lacks the last letters that i wrote, so it's missig these. I try logging in anyway, not changing the name. Does not work. I try adding the last 3 missing letters, still does not work.. And now it's acting up like hell, it won't respond when i press the arrow to log in. And it tries to log in when I'm not even pressing anything... And it won't even turn off when i click that option... So what gives?
