How can I stop my Toshiba Equium from overheating and crashing. This usually happens after about an hours use but also it always occurs (almost immediately) when I try to transfer big files such as videos etc. from a memory card

I had a similar problem with a Compaq laptop. Turned out to be the battery. To see if it is, take the battery out and run it from the mains for a while. If the problem occurs then its not the battery (not much help I know but it illiminates one possible source).

Hi,

The User's Guide is available on this page on the Toshiba website, under the User's Manual tab.

I have also compiled a tip for dealing with overheating issues on Laptops as that is a common issue.
You may please refer to this link for reviewing the same.

This is to do with LAN.
The lights ALWAYS stay on.

replace motherboard

www.drivermax.com
visit the above site, download the free driver utilty and it will scan for hardware, find the latest drivers and let you choose what to install( I used it to "downgrade" from vista to xp on my Toshiba Equium P300D, it was excellent).

If the laptop shuts down and won't boot up straight away, then the problem could be an overheating CPU problem. It could be a faulty fan and/or the fan and heatsink assembly is clogged with dust.
Check the fan and if it has stopped spinning then replace it and if the fan and heatsink is clogged with dust, loosen the dust and remove it.

if the fan is not running continuously then its the fan ans board problem.because the board is getting hot and fan is not running so the board is getting overheated and the machine is nor working.and if the power light is ON and fan is running but only the screen is black/blank then its the problem of inverterboard.the cost of new board is $25 get it replaced fromn near by laptop repair center. thanks.

whats happening is that the cpu is overheating and shutting down the computer due to your fan not spinning, if you wish to test this remove the bottom panel and remove the fan and its cooling tubes should all be one part (quite easy 3 or 4 bolts) and blow on the cpu or put a pedistal fan facing it or any other form of cooling that wont damage it, and try to start it if it boots for a while it is the fan and you will need to replace it, i had this exact problem yesterday

is it running in safe mode just press the F8 key and start in safe mode
and restore the system .
