Laptop's CPU getting to 105C

post #1 of 18
Thread Starter 
So someone brought me his laptop to fix it because it kept restarting after getting to the desktop.

I thought it was a software problem so I did a few things in safe mode. It kept doing the same, but then I noticed the laptop was super warm so I installed speedfan and it showed the copu temp at 90 and raising up to 105.

It will only stay on for a few mins in safe mode and in normal it would restart right after getting to the desktop.

I put the laptop ontop of my Antec 1200's 200mm fan and brought the temp down to 58C and It didn't restart/crash anymore.

What do you guys sugguest to do? I was thinking about opening it up and check if it is dusty inside (even though it doesn't look like it). Change thermal paste?

Pretty much every hardware piece inside is around 60C ontop of the 200mm fan and 70-100C ~ w/o any cooling.

Just open it and clean it. Don't bother changing the thermal paste unless you're absolutely sure you can put it back safely.

What's the laptop's specifications. Link to said machine will help massively.

Ive dissembled many laptops with little to no knowledge of repairing them and it's very easy to clean the thermal paste off and put the heatsink back on with fresh thermal paste.

@ OP. The heatsink on it is probably clogged with dust.

This. As it's not yours, simply open it up and compressed-air the hell outta it! Maybe even try putting the compressed air in through a vent. My wife's Dell has warranty voided stickers over the case screws.

This too. Although, are there any chips that'll work properly @ 105c?

One of the fans may have died on it. See if you can see any fans that are not spinning.

Nope. That's the max temp that laptop CPUs can handle. It's the Tjunction for them.

It's an HP Pavilion dv2615nr.

This is the 7-8th HP laptop I get to fix in a period of 2-3months and one of those 2 had a heating issues, but when it got to my hands the cpu was already fried (I don't recall the model, but it was one of the expensive ones).

I don't open laptops too often completely since most recent laptops have openings for hdd, ram, dvd drive. That's why I did this thread maybe there is another reason of why this thing is getthing so hot besides cloggedd heatsink.

Edit: The heatsink fan is spinning and really fast. I can see through the vents.

clean clean clean time :]

get all that dust out. see if there are anything in the fan that is making it go slow (like some sort of long fabric wrapped around it).

change the thermal paste too.

Get a cheapo laptop cooler if you want to be sure.
