Upgrade P4 for laptop

Hi everyone. My Acer Aspire 1662WLMi laptop has a P4 Processor 3GHZ (478 Socket), FSB: 800MHz, Chipset: Ati IGP9100. As the CPU gets too hot, and its thermal behavior is awful , I would like to upgrade the Processor. Is it possible to replace it with a Pentium M 740 Processor (Socket 478), or would be a problem with the motherboard chipset or the bios version (Phoenix)? I guess that I won't have any problem if I use a P4 CPU instead of a Pentium M.

Thanks

 

The P4 and PM sockets are different, so that is not going to work. Same number of pins, but different socket and different chipset.

All the P4's were thermally challenged, so I don't really see a way to make it any cooler. Check out the Cooling Guide though for some tips that might really help you.

 

As night_2004 says, the only changes you could make would be to put another P4 cpu in as they (along with the P4 based Celerons) are the only socket 478 cpus made.

A laptop cooler might be a good way to cool things down, you could also check your dynamic switching settings and maybe turn the cpu down a bit.

 

If it's a P4 laptop, it could also be old enough and just be losing it's thermal connection, the paste has dried out or something. You could try disassembling the laptop, cleaning out the dust, and re-applying thermal paste to the processor. I've seen that fix a lot of overheating problems.

 

Thanks guys. Well, I am using a notebook cooler and I have already cleaned the fan of my laptop and reapplied thermal paste, but no lack. The starting CPU temp is 74C. For that reason I am thinking to replace the CPU. Unless you believe that there is some problem with the heatsink.

Thanks

 

How old is the laptop? Has it not always run this hot? If you do replace it I would try to find one that's slower, I know that'll do nothing for performance but hopefully it'd bring down temps and increase your hardware's lifespan. I had a 3.06GHz P4 laptop that managed to cook a hard disk....

 

It's almost 3 years old and the last 5 months has been extremely hot, with often shutdowns due to reaching the critical temp. Anyway, I am thinking buy a cheap P4 based Celeron. I hope though that I won't have any problem with the Phoenix bios.

 

If I were you I'd try to get a Pentium because it has Dynamic Switching which should help reduce heat output.
