There is usually a flicker on the screen then a reboot, sometimes several times, after which the battery appears to have almost drained. Switching off, conecting to power supply and restarting restores it to normal with the battery level back to where it was before the reboots. The reboots usually occur shortly after switching on with a partially dischrged battery. The battery could not discharge and recharge so quicky, so I suspect a software glich. Any ideas? John C.
