I have a curious problem on my Toshiba NB500 Netbook. With the PSU plugged in the laptop starts fine and currently the battery shows 95%. It runs with no problem.
With the PSU unplugged the netbook won't boot and shows no HDD detected.
If it is booted with the PSU plugged and then the PSU is unplugged the netbook crashes with a BSOD after a couple of minutes. My first thought was that this was a hardware problem with the battery but I have tried a replacement and there is no change in behaviour.
Anyone any ideas what might be happening?
