the device will not turn on by itself, when I connect it to the ac adapter it will show the nokia startup screen, stays there for about 5 seconds, the screen shuts off for a second and then back again. Does this for about a minute and then shuts off completly, I tried connecting it to the pc, in xp it shows that it has detected a device and then it will say the device has malfunctioned. Doesnt stay on long enough for me to detect it in linux. I dont understand the last thing i did with this thing was read a pdf, hit the power key and select " lock screen and buttons" ?!
