computer get too hot and shuts off

Lately my laptop computer has been getting too hot and shutting off.

I installed speed fan and it is telling me that my computer is getting close to 120 degrees F (really hot!)

I had this problem before and sent my computer in to be fixed.

They said they replaced the entire cooling system. It is doing it again.

Not sure what is causing it but it has not been a whole year since it has been fixed before.

Does anyone have any suggestions for what I should do?

confused


thanks,

John

 

120F isn't very hot for a notebook by any means. It's ~49C which I consider to be a cool temperature for my overclocked Core 2 Duo processor in my desktop. Now at 185F I'd start to get worried. But my notebook runs just fine every day averaging around 158F (70C). I don't think heat is the issue here.

What kind of notebook is it (brand, model, etc)? What are the specifications (processor, memory, video card, etc)?

 

My notebooks getting upto 75c! Works ok though, i was worried about this but had my mind put to rest on here. I read that Pentium+Celeron M are safe from 40c to 85c yesterday. And cut off temperature is 110c for them. Cant help with the problem but thought Id share what I learned myself this week.

 

Does the keyboard and bottom of your lappy get seemingly 'over-hot' when in normal use?
Are your cooling fans running flat out constantly?
These should be the first indications of a heating problem.

Does the system shut down on idle, or only when executing demanding programs?

Have to agree that 120F is not considered overly hot for a CPU temp, but i guess it could be considered so, if it were your motherboard temp?

If you suspect the issue is heat related, check that the CPU heatsink is not clogged with dust and lint completely!


Depending on the model (as OC suggests), you may be able to access the CPU/heatsink area through a latch at the bottom of the laptop, in other models you may have to open the laptop case all the way down.
Make sure you are not voiding any warranties before you open it up, then give it a good dusting with a pressurized air can.
(if still under warranty then do the obvious, brb!)

It may also pay to remove the old thermal paste/pad from the CPU and apply some new stuff while you have the whole show open!
This will aid with the dissipation of heat from the processor.

good luck!

 

whats it sitting on? Get either a chill pad or do what i do "cheap fix." sit it on your table and use 4 bottle caps from a 2 liter or 20oc pop bottle and put them in each corner and set the laptop on them. that lifts it high enough so the surface is not holding the heat and air can circulate under it.

 

yea, basically reiterating what everyone else has said. with laptops its all about the surface its on. put it on something hard and smooth like a wood or similar desk/table. just dont have it on a blanket, sheet, carpet etc. those temps shouldnt be causing it to shut down
