Dell Inspiron E1505 freezes when power is plugged/unplugged
I've had this issue for some time now but no real resolution.
I'm running Windows XP SP2, latest updates, etc. on a Dell Inspiron E1505 laptop.
Basically, and this is intermittent, but often enough to be a problem, when I remove the power cord (either from the wall/power supply, or remove the plug from the back of my laptop) the computer just freezes up:
- The screen goes completely black (although not as black as when the computer is completely off)
- the computer is still 'on' (though not responding), power light is still on, any lights that were already on (NUM LOCK, etc. are still lit up)
- the computer is frozen (I can't see the screen, but I can confirm this because for example if I press cap-locks or the key combo to disable the wireless networking, the lights on my keyboard stay the same)
The only way to recover is to force a shutdown and restart the laptop.
I have contacted Dell regarding this, but they said it's not a hardware problem, and most likely some kind of system conflict. Of course their advice (as always) is to re-install Windows.
I have confirmed that it appears to be a system problem, because I booted the laptop off a Linux live CD, and then tested multiple times to remove the power plug and I could never replicate the problem.
I'm trying to find a solution where I don't have to completely reformat and start over as I have a lot of programs installed.
Any advice would be appreciated. And if anyone else has a Dell laptop with this problem I'd be interested in hearing about this.
