Toshiba laptop reboots when on AC Power

Hi, I have a 6month old Toshib Equium L40-156 laptop running Vista Home Premium. Whenever I shut the laptop down without the AC cable connected (just running on the battery) everything shuts down fine however, when I try shutting vista down while on AC power, the laptop shuts down correctly and the power light goes off but after apprx 3 seconds the power light comes back on and the laptop starts up again.

I tried installing SP1 to see if that would fix the problems but it has not. I have also check the power button commands and all are set to shut down the laptop. In addition, I have also unchecked the automatic restart option in the 'Startup & Recovery' section but nothing has workied.

Thanks in advance.

Toshiba external drive won't instal on Windows 7 Home Premium


Will the external drive work on another computer? Has the external drive been dropped, bumped, jarred? If it works on another computer, shut down the Win7 laptop, unplug, remove battery, remove the USB external plug, plug into AC, reboot, when it is finished, plug in USB.

How do i test the power button on a toshiba equium l40 laptop


OpenControl Panel, Power settings, Advanced Power settings, change SLEEP to Never, Hibernate to never. Shut down and unplug, if you use mostly on AC, remove battery, your laptop when not in use. It will last longer, if there is a power surge not be damaged, and a reboot every day resets the computer.

Toshiba laptop reboots when on AC Power


I have the same problem with my Toshiba too, prima facie, it looks like Toshiba and Vista don't make a good combo. I suspected this to be a pure hardware problem, but was disproven when I booted in safe mode. It does not have any problems with the AC Power on in Safe mode.
