I bought a broken Toshiba Satellite A105-S2101 laptop off eBay. It would freeze on the BIOS loading screen; I found out it was just a bad DVD drive. I replaced it and all is well, except it overheats and shuts off after approximately 15 minutes.


  • it has an Intel Celeron M 420; it’s a Socket M,
  • the fan works, of course,
  • the heat sink is clean,
  • the thermal paste was pretty dry, so I ordered some; it’ll be here in a few days,

If it still acts up after new paste, would one of the other Socket M CPUs better as far as staying cooler? It doesn't necessarily have to be faster.

According to CPU-World these are the available Socket M CPUs,

  • Intel Core Solo
  • Intel Core Duo
  • Intel Celeron M 400 series
  • Intel Celeron M 500 series
  • Intel Pentium Dual-Core Mobile
  • Intel Core 2 Duo Mobile

I read on a Yahoo Answers post that Celeron M's are known for getting hot, and even a Core Duo would run cooler.

But the info on the Xpress 200M chipset says it supports "Intel® Pentium® M, Intel® Celeron®, Celeron® M and Intel® Pentium® 4 processors"

THEN a guy at this link (Notebook Review Post) says he bought a Core Duo CPU and put it into a similar laptop with the same chipset and it worked, so I don’t know what to think.

Anyone have more knowledge on this?

I would like to get a Core Duo T2300E if it would work, and if it would run cooler, they have them less than $10 all day long on eBay. I just going to resell the laptop after I get the overheating problem fixed.

Make sure you have a BIOS version which supports the new CPU. – Hennes Oct 2 '12 at 16:03
Your choices on a laptop are limited to the point the aftermarket on cpu coolers does not exist. Your limited to laptop coolers with fans that blow air into the case ( depending on air vent placement ) or cooling pads. – Ramhound Oct 2 '12 at 16:43
I don't think this will be solved by a new CPU. Replace the thermal paste, lower the fan 'kick-in' speed (so it spins up at a lower temp), lower the CPU tolerance of heat ~5°C (so it slows down when overheating - less speed, less generated heat), and get a laptop cooling pad like Ramhound suggested. – Robotnik Nov 13 '14 at 22:15
