“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.

    I have a Toshiba A105 that is shutting off after 20-30 seconds each and every time. The fan comes on when you first boot it for a few seconds and then shuts off. I am uncertain if it just isn’t getting up to temperature where it needs to kick the fan back in.

    I have tried to run the system on AC only, battery only, and both, but all three yield same results. Tried the two memory modules individually and swapping slots as well.

    System will boot to windows quickly normally and then power off. The problem is not windows-specific, as if you are in the BIOS configuration, it will shut off after the same period of time.

    Any ideas? I am at a loss, and I would prefer not to just start buying parts. The fan works fine and quietly when the system first boots, so it’s not a seizing fan that I can tell.

    Thanks,
    Clint

    I have a sat pro M70, and have cleaned out the heatsink, and put some new termal compound on the CPU, but it has not made much difference.
    I am using Everest to tell me how hot the CPU gets, and when under any load (i.e. opening up word) it peaks to about 65 degrees c. When idle, it sits at around 43. This surely cannot be right (or good!). The other thing that concerns me is that the HDD is sitting at around 48! This is a new drive, as the old one died (probably as a result of the heat).

    Is there anything that you can suggest?
    The one thing in my mind is that the CPU needs to be replaced.

    Thanks

    Hiya,

    I have an A200 PSAE3 Edition, I disassembled and replaced the heat sink also cleaned out my fan. Oddly enough it still shuts down. It’s not due to over heating either… My Laptop only gets to a max of 50′C whilst gaming.

    Any thoughts?

    If the vacuum cleaner is the type that doesn’t have an extension tube, that is the motor will be very close to the laptop, you have to remove the hard disk first, otherwise the powerful magnetic field generated will surely damage it.

    I have a Toshiba Satellite A205-S4577. It just quits responding, the keep board and everything. Sometimes it will shut down for days at a time. I put it in the shop and they said that they couldn’t find anything wrong with it. Any ideas?

    Hello,
    I have a Toshiba Satellite L305-S5875 amd it works completely fine but with only one problem:
    The bottom of the laptop gets very hot, and the fan fails to turn on at all while i’m using it.
    Could somebody give me some assurance that this procedure will fix my fan problem?

    Thanks a bunch :)

    Hi,

    I think you’re doing a wonderful job and I am hoping that you will be able to help me; a friend has given me a TOSHIBA EQUIUM A100-549 LAPTOP.

    The problem with this laptop is that I have difficulty installing either XP Home or Professional because the DVD drive cannot read all the files on the discs. My conclusion is to replace the optical drive, but I need help to remove it from the laptop. I would appreciate your help in obtaining instructions on disassembling this model of Toshiba; it’s my first.

    Thanks for your help

    Regards

    Philip
