“My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. Yep, OVERHEATING!

This is one of the most common problems with Toshiba laptops we deal with.

Indications of laptop overheating problem:

  1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
  2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
  3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
  4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:

If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.

  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

UPDATE: I just received a nice tip from MC N’Colorado. I think it could be useful for all of you with guys:

I decided to use a shop vac to suck the dust out and it worked. I tested it by letting the machine run all night and it worked. It’s been a couple of weeks now and I’m glad I did it. I was ready to take the machine apart, now I’m glad I didn’t. I’d suggest you use a heavy duty shop vac to clean out the fan and heat sinks first.

I agree. Try to fix the problem without taking the laptop apart first but I would recommend using a powerful air compressor instead of a vacuum cleaner.

If your laptop is still under warranty, you can take it to any Toshiba Authorize Service Provider and fix the problem at no charge to you.

    Tanmoy,

    It worked fine for these many years but suddenly few days back i was working with it and it freezed suddenly. I had to force fully, shut down the computer. After that it failed to start. i tried it after 15 days and it started normally and worked for 2 – 3 mins and again stalled the same way as it happened early.

    It’s likely that there is a problem with the laptop memory, maybe one of the modules (if you have two modules installed) is bad.
    Try reconnecting the memory module, try replacing it with another known good module. If you have two modules installed, test the laptop with each one separately. It’s unlikely that both modules fail at the same time.

    Hi,

    I have a Toshiba Equium M40X-230. It’s four years old now and the fan has become extremely noisy. What steps should i take to reduce the noise? (I don’t know much about laptops)! Thanks x

    I opened my laptop and cleaned the heatsink and fan from dust. I turned it on without closing the parts completely and it works fine. Then I turned it off and removed the thermal sink, and it shuts down back on me, about every 10-20 minutes or less.

    How does the thermal grease works by the way? And can I use the Thermalike Thermal Grease for my Satellite 1805-s274?

    What can be the problem with my laptop?

    And yes it was purchased in the United States, sorry I forgot that part of the information before.

    I’m guessing the Part # is same? The Part # is PSPBUU-01900J, Model is X205-SLi2. Anywhere recommended to buy? Thanks

    Memory Hole Troll,

    Do you recommend a metalic or ceramic based thermal paste for this fix?

    I use same Toshiba grease for all laptops I repair. It’s either pink grease (part number: GY4C0000T210-01) or gray grease (part number: X-23-7762-01). You can google the laptop number and find it.

    Ken B,

    I’m going to test it whenever I remember to bring my multimeter home. If I test it and it turns out to be a motherboard (as I figured it may be)

    Did you buy your Satellite X205 in the United States? If you did, you can give me the laptop model number from the sticker on the button (It’s close to the serial number) and I will look up the motherboard part number for you. After that you can research for a new motherboard by the part number.
