My computer keeps turning off, and my dad said that it was the battery so it took the battery out and changed the settings and it still keeps turning off. It turned off twice in the last 10 minutes!
I have a toshiba laptop which was unexpectedly switching off. The laptop was 2 years old. I did lots of searching online to discover this is a VERY COMMON ISSUE. The problem is, dust blocks the heatsink. When I took my computer to pieces, I found a strip of dust half an inch (1cm) thick covering the back of the heatsink which prevented air flow. If your laptop is a couple of years old, this could be the problem. When I removed this dust, the problem disappeared. If you are computer savvy, then try the following - if not, take it down to a computer shop! 1) Remove the 5 screws holding down the heat sink cover and processor cover. These are on the bottom of the laptop, in the centre, at the back. 2) Remove the 3 screws which hold in the heat sink in place. 3) Remove the heatsink 4) Take the dust out 5) Re-assemble a note: be careful not to get dust in the thermal paste on the cpu - unless you have replacement paste. Good Luck!

I have the exact same system. The problem I had (identical to this) is the adapter connection was loose on the motherboard (it was getting enough power to start the system but would turn off and would not charge the battery). Once the pins were re-soldered it worked fine.

Claudia with most toshiba larger notebooks the heatsink gets blocked and air will not circulate. When the computer reaches a specific temperature it shuts off.. a program called everest can check the temperature.. but my suggestion is that you take it to a person that is a+ certified to clean the heat sink coils

Computers have thermostats and my computer kept turning off because it was overheating. I had to replace one of the 2 fans which fixed it.

Hi, have a similar prob on an old presario 1700. SOB runs great in 80mb of ram with XP pro optimized... except the loss of power issue :( It doesn't have a built in wifi, so I put in pcmcia card. battery was dead, I replaced it ( now I get 4hrs out of a battery). Strange happens - System cuts off (screen goes blank, no power on wifi) although the power to the computer appears to be on and drive is spinning. I have to hold the power button for a few sec to actually turn it off (isn't it a sign that the system is still on? but the even manager doesnt' show a thing ! so i guess the sys is not on to record the errors...
Problem is unpredictable, I tried with or without battery, jiggled the power cord in the back etc... can't replicated it. I don't off but hte power is on! Everything I found online regarding somewhat issue is keeps saying dust, overheating .... I took mine apart and there is no sign of dust inside. I put some Arctic silver on CPU and mobo chip sinks I don't think it's overheating as sometimes it'll happen the first thing after booting up (the bottom isn't even warm) and sometimes after hours of watching a movie in bed (with vents closed) - testing overheating theory.
Maybe smdy can recommend another way of testing ?

It's overheating. I have the same problem. You might have to clean out the dust and gunk inside where your cooling fan is.

1. Run the computer using only the AC adapter.
2. Reload the default settings in the BIOS.
3. Let the computer stay in the BIOS approximately at the same time the computer, according to you, will just turn off.

Maybe your power supply connector is bad and is not charging the battery. These connectors sometime break and do not charge the battery.

Toshiba extended the warranty for this or any problem your laptop has, but hurry up the extended warranty ends November 07

Maybe the hibernation function...

Maybe a overheating problem, have you noticed if the cooling fan cuts in every now and then. Does your pc notify you of anything before it shuts down, what was the last thing you were doing when it first started to shut down.

keeps turning off when running on mains when i'm using programs like nero dvd srink an itunes
I"m having the same problem. Sometimes I can let my laptop run for days on end and have no problem, but then one day it will shut off. I keep a cooling pad underneath it that shoots the air up instead of pull away. It gets very cool underneath the laptop. Now sometimes when it shuts down, the clock and date are reset when I reboot, and the light that indicates that the battery is plugged in flickers on and off
Usually during cpu-intensive activities (gaming) or while watching movies, the same thing happens. The fan seems to be running fine. I wonder if it could be an issue with the heat sink?
