Bought a toshiba equium A60 2 years past september it shuts down after a few hours while on main power,no warning ,happens all the time,tried rasing computer to allow ventilation and it seems to help a little but still shuts down more than once a day. please help im really worried it might blow up i my face when i least expect it
My Mom's Toshiba Satellite had a similar issue, started running hot, got a laptop cooler, that worked for a while. Then it started to shut-down without warning. I thought it might be a bad power supply/defective battery. Did a search, found a user group that filed a class-action lawsuit about this issue. Turns out many of those laptops have a design flaw. There is a gap between the CPU heat sink and the intake fan. Apparently the gap gets clogged with dust, animal fur, lint, etc. I removed the bottom cover & discovered the gap full of lint & cat fur. I gently peeled the strip of lint out with a dry cotton swab (wore anti-static wristband while inside of laptop), then blew out the inside of the laptop with canned air. From there I tacked fine nylon window screening inside the bottom cover over the fan vents (very sparingly with Krazy Glue). After the glue dried I replaced the bottom cover, Mom hasn't had any overheating issues since.
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 suggest you need to clean your system plus the dust is covering the air existing from CPU fan. This will solve 90% of the problem you have
Deano, Read this thread and try the same things I mention to see if you are haveing overheating issues. You might need to backup and send in for repair. http://www.fixya.com/support/t121493-turn_off_itself
If ventilating helps, check that the vents on the bottom and where the fan blows out warn air are'nt blocked, try gently hoovering around area witha nozzle.
