My laptop is plugged in and it seems the AC power is fully functional. The most frequent times that it shuts off are when there is a CD inserted in the computer, or I am playing an online game, such as Guild Wars. I have no clue why this happens, and it is very frustrating. I am even using a Targus cooling unit, set under my laptop. Someone please help!
I had the random shut off problem a few times with my zd8000. It turned out that the cooling vents were blocked and the processor was overheating. It has safty circuts to shut itself off when it gets too hot.
Even if you use a cool pad it won't help if the processor can't get the air.
I solved this problem by using a shop-vac (5 hp) to pull the blockage back out through the fans. It turned out that a good protion of our long haired cat had made it's way into the machine. I sucked out enough fur to cover a small kitten. :D
HP assured me the ports couldn't be blocked but in reality it was a different story. Now I clean the cooling ports every three months or so and every time I get more debri.
The zd8000 is a heat monster anyway. You need to keep it cool. Suck out every opening in the case (with power off!). I stir the fans with the sucktion until they get spinning so it keeps the fuzz off them too.
I've been fine since I started the vacuuming. Hope it helps.

Many models of Toshiba Satellite laptops have a capacitor called
NEC/TOKIN Proadlizer which loses its capacitance with time and hence laptop freezes, shuts down or restarts when AC is plugged in. One
needs to replace this cap as

it could be caused by a lot of things. isolate it first. since its randomly shutting down, try first in normal mode. does it heats up before it turns off, if yes its an overheating issue. you may need to replace fan or even motherboard of your pc. have you checked your battery? is it properly seated? or is the problem happening when your system is plugged with the ac adapter? try to check the power cable.
This is the best way to tell. If your system is shutting down on you by behaving like your shutting it down thru windows then it could be a spyware, virus trojan issue going on. If thats the case then run your virus program and see what it finds and remove it.
If your laptop is shutting down on you where everything turns off right away with no lights, kind of like a power outage then go ahead and remove the battery and only use the ac adapter and see if that solves the problem. If it does solve the problem then you know its your battery that is the culprit.
If your only using the ac adapter and the machine shuts off on you like a power outage with no lights then you know its a problem with the motherboard.
With just the ac adapter plugged in, wiggle the cord near where it plugs into the laptop and if it shuts off on you like a power outage then you know its a loose DC Jack and it needs to be resoldered back into place.
Hope all this helps.
Check the CPU and Fan/Heatsink assembly. I have a pretty good feeling that the CPU is heating up too much and is not being cooled properly. There may be lint or dust clogged in the fan. You can get access to this pretty easy by removing a few screws on the bottom panel that houses the CPU/fan.
I think ur laptop goes to power saving mode.Right click on the desktop then choose personalize or properties if u have xp. Then click on screen saver at the bottom click change power settings.Now if the power saver is checked then uncheck it and choose balanced in that change the timings as when it should sleep according to ur wish.
If u have any other problems please ask me..
Goodluck Please don't forget to rate me as fixya..
This problem has happened to me on several occasions. I found that the connector that you plug your power supply into on the motherboard gets loose. Not making a good connection and like you said needs to be re soldered. Before attempting this, stick a small screwdriver in there and see if it's loose.
If it is, then EVERYTHING needs to come off to get to it. Not a quick project. I suggest you take pictures along the way just in case. Good luck!
