"Its not the heat, its the humidity" Well actually it is the heat.

When I start Firefox with a few widows and about 60 tabs my laptop overheats and does a thermal shutdown.

Yes I have a cooling pad. Yes I've cleaned the cat hair out of the fans :-)

The trip point is set at 81 degrees Normal cruising, t'bird, OOo editing, adobe, other graphics stuff including composing with XMIND and export as graphic and GIMP editing the temp sits at the low to mid 60s.

This is a Compaq presario X6000

So:

a) is 81 a realistic trip point? b) why is it only FIREfox that overheats its is the FIRE? c) how do I set the trip point?

I'm still on openSuse 11.2

Well, You still have a few fuzz-bunnies in the intake/exhaust flow. When you clean the fuzz out -- you need a real vacuum -> 5 H.P.+ shop vac type. WARNING: Before you use a vacuum on your laptop, take paper-clips, un-bend them into roughly the shape of a square 'C' so that each of the ends can pass through the grate covering the fans and prevent the fans from spinning when you start sucking. Make sure the paper-clip completely stop the fan from spinning and make sure you can hold them so they DO NOT come out when you run the vacuum over the fan grate. When you do use the vacuum, I have found that the circular-brush (or just the end of the hose if no circle-brush attachment) works the best. The key here is that you need to be able to direct all the suck power over the grate at the same time so you don't end up with an air loop created at the uncovered part of the grate when you pass the vacuum over it. The brush attachment helps to create the seal when your fat fingers are there holding the paper-clip in place. Do ONE fan opening at a time (if you have multiple fans). Passing the vacuum over the grate in a sweeping motion side-to-side making sure you have complete coverage of the fan grate when you pass over the middle. Stop after a couple of passes over the first grate and pick the fuzz out of the grate. Either rub your fingers over the fuzzy grate to help roll and pull the fuzz to the outsize or take a stick pin and bend the end into the shape of a hook to help pull the fuzz out. Do the Fuzz removal on ONE grate BEFORE moving on to the other to prevent sucking the fuzz backwards though the system when you move to the next fan. (of course if you only have one fan, don't worry about it). Once you have the fan grates done, then move and suck from the exhaust opening in the laptop. MAKE SURE YOU STILL HAVE THE PAPER-CLIPS BLOCKING THE FAN. The best you can do here is to just use the end of the hose and use your hand to make the best seal between the hose and your laptop case. Do the same type of fuzz removal here after sucking -- being careful not to bend any of the fins on the exhaust heat exchanger. (Repeat Once more on each opening) Remove paper-clips and give it a go. On the temp issue -- that is processor dependent. 45 degrees can be hot on some while 110 degrees is OK on some P3/AMD XP class chips. All chip manufacturers have the allowable temps listed for their processors and many web sites have a summary of this info -- google is your friend. With a clean laptop and armed with the manufacturers allowable temp information -- you will then be in a position to answer your own question. Have fun :p -- David C. Rankin, J.D.,P.E.

Just let it run again, open your 60 tabs and monitor your systems load with e.g. "top -d 1", and you'll quickly find out what runs ypur system into max heat. However, a stable machine should be assembled in such way that it can handle max load without getting overheated. It could also be both software problems (Firefox, high load) and hardware problems (Is the fan working? Has the cooling element gotten slightly dislocated over time?...) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
