Lappy reboot on start up

[richie281]

Hi guys,
I need your help with my old lappy again. I'm using HP NC4000 and about 2 weeks ago, my laptop started to reboot on start up whenever I used it on battery or the PSU directly. After about 3-4 reboots, I can used the computer but it does not recognise the internal bluetooth card!!!
However, If I put in onto the PR1001 docking station, it works just fine with no issues at all. How weird is that!
I'm using the original PSU for the docking station and use the HP Auto/Air/Power PSU when undock.
I got the USB_BUSCODE_DRIVER blue screen on reboot but cant read the rest
Help me please. Thank you
