Surface RT with dead battery and won't recognize charger
15 - 30 minutes
After checking the Microsoft website and finding out if I send in my tablet(in good shape) with $320 They will send me back a refurbished one. (EBay has them for $99.) I decided to take it apart what the heck it doesn't work anyway. The charger seemed to emit 12 volts. I ordered tools and a charging port from iFixit and about a week later I dug in to it.
The hardest part was getting the bezel off with spudger tools. But it came off with only a few scratches. I read somewhere all you needed to do was unplug the ribbon cable and plug it back in and the problem would be reset so with lots of light and a magnifier I did it( I'm an old fart). The reason I didn't replace the charging port was I had no T4 screwdrivers. The port was not the problem anyway.
Don't be afraid to dig into it and possibly brake something. What the heck the thing doesn't work anyway.
