Laptop Cooling Problem


I have an older laptop, a Toshiba A45-S151 and it has recently developed a bad fan problem. Either the fan does not work at all or when it does it runs extremely loud. I believe the bearings to be worn out from the 3 years of constant usage.

Unfortunately I cannot seem to find any documentation anywhere showing me how to access the main fan. I've pulled the thing as far apart as I could figure out to do without detailed specs (Toshiba's idea of 'detailed specs' is laughable) or diagrams and still have not been able to get into that small compartment.

I've upgraded the RAM and the HDD in the past, I've also cleaned the heat sink and 'cleaned' the inside with compressed air from time to time. Oh, and I've applied new thermal grease to the heat sink twice in the past. This knowledge however does not extend to getting to the fan.

Do you know of any documentation that could help me see exactly what I am doing wrong so I am no longer prohibited from replacing that part?

    I appreciate you taking the time to respond, but I disassembled it as much as I could figure out to do based on screws, etc. and still could not get access to the fan. Access to everything else but.

    I turned it over to 'the professionals' (meaning the people who have access to the assembly guides) 2 days ago, so really don't need any more assistance in the matter.

    While I have many years of exp with computer building/modding/programming/etc., when you cannot find where something attaches and you don't want to push too hard on something (that the assembly guide might be telling you to push hard on) because you don't have the assembly guide and don't want to risk breaking are stuck with letting others do what you know you are capable of.

Don't think you will find any documentation online to help you disassemble. Unless someone around here has some Toshiba field service manuals in pdf form.

Sounds like you just need to replace the fan. They do go bad over time. Also, don't used high pressure compressed air to clean out a fan. Unless you hold the fan still using a small screwdriver. The compressed air, if too much, will ruin a fan's bearing if you let it spin freely while blowing out. The canned compressed air showed be ok though.

You can search on ebay for a replacement fan, might be used though. Could do a google search for a new one. Somewhere like

And I think the A45 may have two fans in it. If you can get inside of it, which sounds like you have allready, then you should be able to easily identify the fan(s).

    Just a few quick tips...  sit down and methodically take the thing apart. It's pretty simple. Look for hidden screws... also catagorize the screws you take out into little cups. Like, base screws in one cup, motherboard screws in another cup, etc.. it should come apart fairly easy.

    I found a guide online that may assist you...

    Not a bad idea :-) ... when in doubt, let someone with experience tackle it. Beats breaking something else anyway. LoL.

Hi, I've recently obtained a Toshiba Satellite

Have you since re-inserted the battery to see if it charges? A battery that is past its ability to hold a charge may show as fully charged, but will discharge usually instantly if put under load and one that has deteriorated to the point of no longer accepting or retaining a charge can cause problems that you have described. The best way is to obtain another battery and test that in the laptop. If that too fails, the issue is likely to lie in the charging circuit. Some laptops, the Packard Bell easynotes were notorious for this.

It is also good practice to remove the battery once charged and running on mains, as this extends the battery life

Fan noisey and cmt getting hot on my toshiba a45

Replacing the fan may not be for the faint of heart. Alternatively, buy a can of air & blow the darn thing out. Though not always the best course of action, I sometimes do it with the notebook turned on. This way, I stand a better chance of expelling the gunk than if the fan blades were stationery. Next, I would buy a $15 laptop stand with a usb-pwered cooling fan.

Cant find ram chips in a Toshiba Satellite A45-S151

The memory is under the keyboard on this laptop. You should be able to pry up the keyboard with a small screwdriver between the keyboard bezel and the keyboard itself.

Be very careful not to break the wires connecting the keyboard to the internals of the computer.

I hope this helps.
