Compaq Presario C700 Shuts Down Frequently

I am having Compaq Presario C700. It Has: 1.73 GHz Pentium Dual-Core Mobile Processor T2370, Up to 2 GB DDR2,

Recently i have noticed that the laptop shuts down frequently when i am listening to music, while watching movies,or sometimes when working. I did a bit of research on the problem and i found that most people are saying to Find the Manual on COMPAQ.com and look at specs in order to open up the laptop, then spray/clean the fans/or heating parts. Is that the correct thing to do.

Re: Compaq Presario C700 Shuts Down Frequently

Many times a laptop overheating is directly related to the cooling of the processor. The main culprit is the fan. The fan sucks in air from the bottom and blows it out the side. It will also suck in hair, dust, and other debris. That stuff often gets trapped by the heat sink and over time builds up in a layer which chokes off the cool air going to the processor making the fan work harder.

What I recommend is getting some canned air and blowing out the vents in the side and bottom of the laptop. If after doing this you still have problems with over-heating, and your laptop is in warranty, you can take your laptop to a HP Authorized Service Center and ask them to clean the fan and heatsink. You can check your warranty here:

If it is out of warranty, consider searching for the maintenance manual for your specific model, in the manual there are schematics for taking apart the laptop. Cleaning the fan is much easier that removing a motherboard, so don't feel to intimidated by the idea. Also you can remove the heatsink and then remove the thermal grease and apply a new layer which also helps alleviate heat related issues.

Hello yes we do recommend that

 

Also  a Chill pad is not a bad idea, we do have some available on our accesories website

Also- here is a document on how to clean out the vents, all though it does not give out the PSI - it does recommend a can of compressed air  so the PSI should be about the same.

Document on cleaning vents.

Notebooks can shut down and run up to 40 % hotter with dirty vents and fans.

    Re: Compaq Presario C700 Shuts Down Frequently

    I have tried everything stated hear-cleaned the fan, heatsink, applied fresh heatsink cream and replaced the cpu. And it still shuts off after a while around 5 mins. Is there anything else that can cause this problem.
