This is a discussion on Nokia Lumia 710 within the Windows Mobile forums, part of the Tech Support Forum category. My lumia 710 has a weird problem, when i connect it and I shut it down it does not start
The phone si aprox 5 years I think and it does not turn back on, it vibrates and it stays dark. The only way to get it on again is to take the battery out and disconnect it. How do I know it is in sleep mode?
