Fan stopped working, replaced, still not working, laptop overheats

I have a Compaq Presario 2200 and the fan stopped working. It had always overheated before that (guess that's an ongoing issue with these). We replaced the heatsink and fan and the fan does still not start although it can turn easily if you manually turn it. I guess it's possible we got a bad replacement fan but I doubt it. What else could be causing the problem in the fan? Are there other parts we should replace?

    Yes we did recheck all the connections, and we don't have the ability to test the fan. Assuming the fan and heatsink are ok (at least until we can get them tested), and that it is installed correctly, and all connections are being made appropriately, what else could it be? Is my motherboard just failing?

    Hi, well, we flashed the BIOS and the fan started working while that was going on, and hasn't turned on since. The next step we're going to try is to add some thermal paste. I will let you know if we resolve this so that this will be up for others to find a solution. Let me know if there are any other suggestions, please.

    Presario 2200 laptop fan never runs. The system doesn't seem to get hot but it doesn't run perfectly either. I'm glad i found this post today. I was just about to buy a replacement fan. I'm thinking maybe the thing just doesn't get hot. It has an m processor, and maybe im just used to the old pentium full blast fan nonstop. Any suggestions?

    i own a toshiba m30x series which is 5 years old. recently i noticed the heatsink fan making a wierd noise which made the fan to stop running.
    All i did was,
    1. Open the laptop, while i did that i noticed wher each screw went by drawing a diagram and labeling similar screws to wher they went.
    2. Theres a long procedure as you get to the heatsink so be patient.
    3. remove the heatsink and also the fan which is screwed on the heatsink.(ther could be different types of heatsink and fans.some fans would be permanently stuck to the heatsink)
    -While u do this step, make sure u dont mess the processor with dirt from around the laptop.)
    4. washed the heatsink throughly. (mine has shitloadsa dirt onit)
    THE MAIN PART:
    5. Clean the FAN getting rid of all that dust and wierd sticky dirt of the fan blades.
    6. Theres a sticker which has info on the fan specifications. PEAL IT OFF slowly.(u need to put it on back once done) you will notice a metal pin popping out.
    7. clean the dirt off under the sticker and then spray very little WD40 (used as an anti-rust element for autoparts)under the sticker.
    8.now Fix everythin back on and your done.

    - If possible clean the top of the processor with alcohol and replace the thermal paste on the processor with some new one. You will also have to clean up the the old thermal paste on the heatsink. This will increase cooling capacity and performance only if your laptop is older than 3+ years

Compaq presario CQ60 laptop overheating and keyboard stops typeing and everything is connect to it like it should i took keyboard apart to check it it does this when it overheats


Usually a laptop overheats due to dust blocking the Fan, vents, heatsink or improper air flow, due to obstructing the vents, fan , etc. Use a Can of Compressed Air directed into the fan, vents. Hopefully you don't need to replace the Thermal Paste on the CPU/GPU , and opening the Laptop to thoroughly clean with Air and a small brush. A laptop Cooler is a option. Use this as a guide, HP Support: http://h20000.www2.hp.com/bizsupport/TechSupport/ProductList.jsp?lang=en&cc=us&taskId=135&prodTypeId=321957&prodSeriesId=3768152 AND: http://www.youtube.com/watch?v=UmR5v-yM9z8 Use ESD protection, take your time, take pictures or video to refer to. Mind the tint screws.

Compaq Presario 1700T overheats and shuts down


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with 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 sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Presario 2200 CPU fan appears to be dodgy


Not really, since the fan is controlled ny a thermal sensor on the Motherboard. You may want to start by having the fan and heatsink assembly replaced.

My hp presario v2000 battery/fan does not work


The fan most likely needs to be replaced. When the computer overheats as a safety feature it shuts down. If you do not know how to replace the fan take it into a repair shop. The does not seem to be the problem.
