I put my N800 to the side for the month and today I went to use it so I plugged it in and the white Nokia screen came up as normal and then about 5-7 seconds later flashes to black and then the white nokia comes up again. If I hit the power it just flashes the Nokia startup and then dies like it had a dead battery. I've had it for about 4 months so I wouldn't think it's a battery issue but that's my first guess. I hadn't installed anything as of late so I wouldn't have thought I bricked it in any way.

Any ideas, I'm going mad from this.
