laptop overheating?

not sure here as i don't really have any experience with laptops...wife's laptop randomly turning off every now and then, i suspect overheating.

its a toshiba L300E, pretty basic laptop. AMD X2 athlon (CPUID reports turion?) 2GB ram, etc.

cooling heatpipe and fins are not clogged in any way, neither is the fan and fan appears to be fully functional. i took it apart and reapplied thermal paste (used AC MX-2 paste) and that seemed to drop the temps a couple degrees.

ok then i ran a stress test with sisfoft sandra burn in while it monitors temps - it didn't crash and ran fine, but the temps were around 72ºC which raises a few red flags in my mind....granted its a laptop and under full load, but still. is this normal for laptops??

any advice appreciated!
 
anyone? anything?

come on guys, even just if the temps are within normal range or not would be helpful here!
 
Your CPU shouldn't be that high for a laptop..... Try getting a coolng pad. Good ones run roughly $40
 
thats what i figured, thanks for the reply. that gives me some confirmation to do that.
 
I use a cooling pad on all of my laptops, but I also clean out the fans and grills on a regular basis to keep the airflow good. If that doesn't work I'll replace the factory installed TIM with a new one....they tend to shrink or get compressed over time, making the computer overheat.

I wouldn't say 72C is outta pocket for any computer after running a stress test.

That being said I always used an actively cooled pad with mine.

I could always tell a heat related shut-down was imminent when the machine got laggy and stumbled all over itself.

Have you checked the Event Viewer for warnings?
 
I had a Gateway that was around those temperatures since the time I bought it; I never had a problem with it.
 
thanks for the replies. i'll check the event viewer, keep forgetting thats there. too oldschool :p

if that temp is in range, i have a theory. wife likes to lie in bed with laptop on her lap...with a blanket that could easily block the cooling fan as its on the bottom. stress test passed with 72 C because i left it on a table to run it, so feet keep the bottom clear.

to solve i'm just going to buy a piece of clear acrylic and cut it to the size of the bottom of the laptop. use some good velcro to attack it to the laptop feet, voila portable table. use the soft part of the velcro on the bottom of the laptop to make it fairly unnoticeable. if that doesnt work i start looking at other ideas...
 
I had the same problem with my laptop last year, it was very hot and I opened it and clean the old stuff between CPU / Northbridge and heatsink and applied new stuff (white) used in electronics for high power transistors. The temperature was around 70-75 celsius degrees and now it is around 60-65 degrees in the summer.

From time to time is better to change the stuff between CPU and heatsink.

My 2 cents! :)
 
Yeah, I second reapplying the thermal paste if you're comfortable with that type of thing. I do this with all video cards/motherboards/etc that I buy for personal use. The stuff from the factory is designed for ease of manufacture and to be less error prone. It generally isn't the best in terms of performance so if you take the time to do it right you should see a significant difference.
 
Try cleaning out the fans inside. I did that and my computer dropped by 20 degrees.
 
Stress testing a laptop is a good idea to make sure it can run at 100%, but unless you are running F@H 24/7, your laptop should never see 100% cpu utilization for any length of time.

Laptops in general do a good job of cooling, but given the finite amount of space, it will never cool like a desktop can. I use an NZXT cooler for the lappy in my sig. It does run F@H 24/7 (unless I am traveling to / from work). The cooler can keep my laptop about 5 to 10 degrees cooler. My temps @ load are about 75 or so. TJMAX on the QX9300 is about 100 or 105 (can't remember right now), so I have plenty of room.
 
As soon as the notebook shuts down can it be powered on again? If not...it's definitely overheated.

...and to clarify...it is shutting down right? Not restarting?
