I have a Vostro 1500 laptop, just over a year old.
O/S: Windows XP Pro, SP3
CPU: Intel Core Duo 2ghz
A few days ago as I unplugged the power cord to move to a different room, as I have done hundreds of times over the past year, the laptop rebooted. Thinking this was odd, I let it boot completely off of the battery, then plugged it in. Nothing happened, apart from the computer registered that it had been plugged in and was working off of AC. So I unplugged the power cord again, after checking to see that the batter was, in fact, fully charged. Again, it rebooted. So, I decided to check the Event log to see if it logged any errors. The event log didn't show anything out of the ordinary for the laptop.
So I decided it might be a hardware issue. To check, I manually rebooted the laptop while it was plugged in, and then unplugged it at the BIOS screen. To my surprise, it kept booting up. So I plugged/unplugged it at regular intervals, partway through loading Windows, the action of unplugging the cord once again caused a reboot.
I am clueless as to what is going on, other than it must be a problem with a Windows component. Does anyone know anything I can try?
