Toshiba laptops and heatsinks

A plea for help/info/assistance from the knowledge base out there please.

My Toshiba laptop has taken to suddenly turning itself off for no apparent reason (although I'm sure there is one). This is normally preceeded by a few minutes of 100% CPU activity and the area over the heatsink feels very warm afterwards. Interestingly though, sometimes it doesn't do this at all and runs quite happily for as long as you want it too.

A quick search found I share this problem with most other Tosh laptop owners and by working through the flowchart I am now at the point where getting to the heatsink and giving it a good clean would be the next step.

Now I'm not bad at taking stuff apart, it's putting it back together I usually have the problem with. Added to the fact that I'm supposed to do all this with a fancy wrist strap on and need to purchase this, the relevant torx bits, thermal grease, etc. I have decided it would be better to leave this in the hands of someone else and hope this will cure the problem.

Several questions.

1. How much should this cost. Been quoted between £38.50 and £200 so far!!

2. Should I trust it the local bod with his little shop on the High Street or is it better to go to a Toshiba service center because they will know what they are doing (or maybe not...).

3. Anyone here fancy the job for cash?

All answers gratefully recieved as usual.

Cheers.
 
Mine did this for a while, it was running ok then bop power off!. Sent it back to Tosh for repair, turned out to be the external mains Power unit. It was giving enough juice to make it look like it was on mains but flattening the battery at the same time. Once the battery discharged the laptop shutdown (without warning as the O/S thought it had mains)
 
Tried running it off mains without the battery in, with the battery in and just with the battery and it did the same trick all the time. Given that it does feel very warm after a shutdown think this is my next option. My balcony may well be the one after that...
 
I'd give it a go if I were you. Thermal grease is a must, otherwise you won't get a decent contact to the CPU. The wrist strap thing isn't a bother, just touch something metal & earthed before you start messing about with the machine.

They're designed for IT bods to work on and they're all as thick as shit.
 
You know there's a clue in the 100% cpu part above. Check in the task manager to see which process is doing it, and google for known causes.

Home computers never run flat out just doing normal web/word/mail stuff, so you might want to fix this problem before you take it all to bits.

Excellent point. You might want to run a HijackThis logfile and post it here for analysis.

See THIS thread for more info.
 
Just did the deed! £35 worth of bits from Maplins 'cos they only had industrial size of everything. Removed a big wad of lint from the heatsink. Put it all back together with thermal grease and blasts of compressed air and amazingly it all started. Total job time about 30 mins.

Laptop now been running for about an hour, no probs. Air out of the vents is only lukewarm and CPU usage currently 5% and been averaging around there for a while. Think the 100% was occurring when things got hot. Area over heatsink is tepid at most. As a bonus, the whole system is running faster as well. :thumb

Hopefully saved meself a bit of wedge, have got the bits to repeat the process loads of times as necessary and am now off to secure myself a highly paid IT job!

Many thanks to everyone for all the info. The irisvista link was perfect.
