Toshiba Satellite P30 and P35 laptops. Removing and cleaning heatsink to fix laptop overheat problem.
Overheating is a very common issue with Toshiba Satellite P30 and P35 laptops. If your laptop suddenly shuts down by itself and the bottom of the laptop base is very hot then most likely the laptop overheats. It happens because the heatsink gets completely clogged with lint and dust and doesn’t disperse the heat properly. Unfortunately, this model doesn’t have a hatch for an easy heatsink access. To remove and clean the heatsink the laptop has to be taken apart completely. Disassembly process is very similar to Toshiba Satellite A70 and A75 model. After you remove and clean the heatsink you should apply new thermal grease on the CPU, do not use old grease. You can buy thermal grease in any local computer shop or online. Artic Silver is a good brand.
If you are not sure that you can take apart the laptop, do not open the case. Try to clean the heatsink and cooling fans with compressed air first. Buy a can of compressed air and blow inside the openings on the bottom of the laptop. If the heatsink is not clogged completely, this measure might be enough to fix the laptop overheating problem.

The laptop should start with memory module in either socket. You just didn’t seat it properly.

WOW CJ!!!! i didnt know what you meant by reseating the memory modules….
but i took out the memory and placed in on the lower socket instead of the
upper one (where it was originally placed i think)… and BOTH LAPTOPS
BOOTED and seem to work fine!!!!!!!!!!!!
can you tell me what happened?
THANK YOU!!!!

Don’t worry; most likely there is a loose connection somewhere. Did you try to reseat the memory module?
That’s very strange that both laptops have the same problem after disassembly. I’ve never seen that ESD can cause such a problem.
You can try to minimize the system. Connect the system board, CPU (with cooling module) and memory. Nothing else, not even the LCD screen. Connect an external monitor and try to turn on. You should get a video output on the external monitor.
Again, check the memory module.

nope i didnt.. I just removed the MOTHERBOARD… cleaned up the dust around
the fans… i didnt touch or move the cpu, i didnt remove the fans… or
removed the hit sink neither….
how could i have damaged 2 P35!!!!??
i also switched motherboards between cases.. still didnt work.. same problem
on both units.

Hey Gary,
Did you remove the CPU from the socket during disassembly?

After disassembling Toshiba Satellite P35 laptop and putting it back together, the computer won’t start up. The power led lights (3 green lights on front of computer work). When I press power button, it turns blue, the 3 green lights turn on, the fans start, but the LCD won’t turn on, after about 10 seconds it either stays that way or shuts down. Also the green light showing hard drive operationg won’t work. Tried to boot without battery, with battery only, no memory card, no hard drive, no wifi.. and exactly the same. The computer just won’t START UP anymore. I was thinking maybe i connected the LCD incorrectly, or I damaged the Motherboard while taking it out? or disconnected something? I did the same with another P35 I have, and i damaged it in exactly the same way. So now I have 2 P35 that won’t start up/turn on/boot up.
ANY IDEAS? Please reply to garyintokyo@hotmail.com with help.
