    OK, here's the deal. I have a Toshiba P25 17" laptop. Whenever I perform a hefty task such as burning a DVD movie or converting large files, the laptop just shuts down.

    Now, normally, I would think just overheating, right? But, I don't think that's it. I have a large fan blowing directly under the laptop, and the laptop itself is on a notebook cooler pad with two fans built in. So, here's the different topics, let's discuss what could be the problem.

    1. Overheating.
    2. Cheap RAM - (I have a 1024mb stick of cheap-o RAM from NewEgg.)
    3. Power Issue - Although my laptop can run without AC power, I always have it plugged in. But, it's plugged to a 10 outlet surge protector.

    COMP CREW, help me out here. There's got to be some pros here who can help me out.:cool:

    My guess from experience would be overheating. What I have done to resolve this on HP and Compaq laptops was to get a can of compressed air, and then blow out all the vents on the computer. That usually takes care of it. Otherwise, I would guess some sort of power issue.

    My laptop does something similiar (Sony Viao PCG-V505DC2)... just surfing the web with it. After a few hours, it just dies. I too will try running memtest

    ok, Having had this problem.. here is the reason and the fix.
    Most comp companies use cheap thermal paste and dont tighten the screws very tight.. After a bit the heat sink on the cpu gets loose and since they use cheap and very little paste you get shut downs.
    Most comps have an access panel to the CPU, or you may have to take off the whole back.
    If you have the right tools and materials
    1. good set of screw drivers(some use torque drivers)
    2. Can of air
    3. Toothbrush
    4. Thermal paste
    5. Alcohol pads or cotton swabs and bottle of rubbing alcohol.

    Make sure unit is unplugged and battery is removed.
    it takes about 20 mins to remove cover,remove CPU heatsink/fan.
    Clean top of chip,clean fan/heatsink combo. Apply about a dime of paste(little less,but if you use a dime as a go by , it should be ok)on the bottom of the heatsink that touches the top of the chip.
    Assemble in reverese order as you took apart ,making sure you tighten the heatsink screws(dont strong arm them though).
    While your there , blow out any dust on the exhuast vent.
    this should solve your problem.

    Or you could mail me your laptop with all your personal porn pics,credit card , bank info,personal info, along with $100 to my PO box and I'll get back to you:naughty:

    OK, but is it alright if I mail you a money order for $25,000 and you wire me $24,900 in cash? Oh, and I live in Africa. Get back to me.:wiggle:

    Thanks for the tips, I'm trying tomorrow night.

    Is it still under warranty, if so just call Toshiba and have them troubleshoot it. I had to exact same problem with my HP, plugged into AC or not.....however it would do it at complete random.

    Since it was under warranty, I sent it back and they replaced the charging/power unit and i was good to go. It's a hard call about overheating since you seem to have a good cooling solution. Have you just left it on and let it run just to see if it's not overheating due to stress and just coincidence?

    It runs overnight fine, but if it works hard, it will turn off. ... Stupid computer store is closed on 1/2/06. Getting special screwdrivers and air dusters.

    I got the T9 screwdrivers and a giant can of air. I opened up the fan compartment and got Q-Tips. I Q-Tipped the fans and then dusted away the particles.

    Question: In the fan compartment, there are these gold-colored metal things. They looks like copper-tunnels. They travel from the CPU to the fans. They were caked over with dirt/dust. I got it all out with Q-Tips and can air. Could this have been my problem?

    following this for an answer.. but i have 2 questions.

    1. does it just turn off as in black screen and no power or does it freeze and you have to manually turn it off and reboot?

    2. Mine does the latter of the last question. Could my problem be the same thing? I know that my battery sucks as it only lasts about 30 minutes but I've also noticed that my 1.7GHz P4m processor is running at 1.21GHz. what the hell?

    Another possible cause is that your battery could have a dead cell, so that it can't produce the necessary voltage to run all of the devices in your laptop at once. DVD burners eat up tons of juice, sometimes more than the CPU itself. Meanwhile, I doubt the computer is overheating, because burning a DVD doesn't take a lot of CPU activity. If it were overheating, it would shut down randomly.

    Your laptop runs at 1.21Ghz because its saving power. If you dont want it to do that you can change the power setting under the bios

    I had an Ibm with the same situation. IF you go under setup right away when the comp starts up you can change the power management. Mine did it even with the ac cord in. But once you change it, it will run at full speed.

    Sweet... I'll try that tonight. As of now, I'm calibrating my battery so I can't shut down.
