Toshiba Satellite A135 -- how to clean fan?

My laptop is about a year and a half old, and air no longer comes out the vent for the CPU fan, so I guess it's time to open it up and clean out the lint.

I read on the web that some Satellites have a cover you can remove to clean the CPU fan, but with the A135, the fan is behind the plastic cover that covers the entire bottom of the laptop. Can I just remove this bottom cover? Or do I have to do a complete disassembly starting with the keyboard, etc?

If you have experience with this model, please let me know what I need to do! Thanks in advance.

    Thanks, bubles134. Sounds like it should work, but I don't have a vacuum cleaner (hoover) to **** the dust out.

    I would rather open it up to clean the lint out, and am not afraid to remove screws, etc. What I really want to know is, can I simply remove the bottom cover? Is it as simple as that? Or is there a long procedure to follow, to eventually get at the fan?

    I have the same sort of problem with my Toshiba A135-S4427. I blew out the dust in October, but now the fan is "grinding" loudly and I'm concerned that the bearings are going. I found the instructions for step-by-step disassembly of the A135 (, but I can't find the fan. It will take 2 or 3 hours to get to the fan and replace it, but you must remove the motherboard and disconnect all of the components and the screen. I wonder if jiminminn's fan has the same "grinding" noise in the A135. The difficulty in finding a fan suggests that it is unlikely to fail--and I never had one fail before! Still, I don't want to have the fan fail completely and overheat the CPU!

    It is that simple in most cases. On most laptops the screws on the bottom that are for holding the machine together usually are marked with an arrow (not always). Do it slowly and maybe even map out which screws came from which hole. They may be different lengths. It will help when putting it back together.

Toshiba A135-S4527 starts to power up then shuts down.

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

The MOST common problem with laptop (CPU) over-heating is caused by DUST/LINT...

That would be normal, as the variable speed fan comes on only when the computer is under load.

What is not normal is that the fan is not coming on when the computer overheats.Or that the fan is not cooling enough when computer is overheating.

Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.

If fan comes up but does not cool enough, then replace the fan, it is not efficient anymore because of a bad bearing or dust. ~Also ensure that fan is well mounted, if fan has poor contact with CPU surface , cooling will be poor.

If fan does not come up, and critical temp is not detected, then the sensor on motherboard is bad, this is very uncommon. When this happens the problem is usually related to system or power settiings , rather than overheating.

If fan does not come up and temp is critical, then fan is faulty, replace it.

There are also more than one fan on many laptops, check that one of the fans (CPU fan, video fan) is not completely ded, and therefore cause for the problem.

By using the software below you can also find out if the problem is really overheating. If temperature results within normal range, then usually it is not overheating.In that case test systtem and check power saving settings.

Here is the software to control your fan and temp. sensor state:

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.).

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 A135) 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.

Laptop heats up then shuts down cools down starts again does same thing again

That sounds like the cooling fan is either plugged up, or it is faulty, or the cooling fins for the CPU heat sink are plugged up with lint and dust. The cooling fan on that toshiba should be accessible through a cover panel under the pc notebook. Remove the cooling fan and use compressed air in a can to clean the cooling fan and the cooling fins to the CPU heat sink and be sure that the air intake vents for the cooling fan are also clean and free of any dust, dirt, or lint. Here are some images that are similar to help assist you, and let me know if you require any further assistance.

I have toshiba satellite A200 series, it's being two and half years since I bought it. Problems: - When I turn on the computer, the computer keep on going in normal way, but the problem is sometime,...

I repaired a A210 this week with a similar problem, it was due to overheating, I even had to reflow the GPU to repair it due to graphics errors. <div>Check that all of the air vents are left unblocked and that your fan is spinning and expelling warm/hot air. It is recommended you use your laptop on a hard flat surface to ensure some airflow under the laptop. You could try purchasing a can of compressed air and blowing it into the vents to loosen up any built up of dust and hair.<br /> If you are skilled enough you could open the laptop up to completely clean the fans and heatsink. Whilst it is open you can remove the heatsink, clean the old thermal paste off of the CPU and GPU and apply a very thin, evenly spread layer of fresh thermal paste. Then put the machine back together.<br /> <span class="apple-style-span"><span style="font-size:10.0pt; line-height:115%;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;;color:black">As for the fans, download a free application called SpeedFan and read through it. It will monitor your core temperatures and it has some options for controlling fans if your hardware allows it.</span></span><br /> Hope this helps,<br /><br /></div>

Fan noise

Is the fan making an unusual noise or just sounding normal but on more then it used to be? If its just on more than it used to be then it will be because the cpu is running hotter than it used to. They are set run at diff speeds depnding on how much cooling is reqd. Is the laptop being used in a warmer place than normal/before?

It may be that the thermal paste between cpu and heatsink isnt performing as well as it used to and needs replacing.

Overheating / Freezing Issues

Buy a can of compressed air and thouroughly clean out your fan vents, etc. Put something under the laptop and see if it runs cooler with the space underneath. If I had your laptop in front of me I would probably test the CPU and at the least clean and put new thermal paste. Did you recently increase the memory? Many times an increase in memory will cause the laptop to run hot. Check to see what you have for RAM, if two chips take one out and run laptop and test heat levels, if no change, swap out the chips and try again. If all else fails try
