How do I know what CPU to upgrade to on my Laptop?

I have a Sony Vaio PCG-GRT170. It came with a Pentium 4 2.8 GHz Desktop CPU. Sounded great when
I bought it, but I am having real problems with heat. It overheats ALL THE TIME. I mean, I can't even
use WinAmp 5 without it overheating.

I have installed hMonitor to monitor temperature; as I type this -- running only FireFox -- the CPU temp
is 181 degrees. Ridiculous.

Anyway, I'm thinking that a new CPU might solve my problems. My question is, can I install a Pentium M
on the motherboard? Or do you have to have a special Intel chipset to install a mobile CPU?

Here's a copy of the question to Sony Online Help:
Harry_> Welcome to Sony online support. I will be glad to assist you.
dan> Is the PCG-GRT170 CPU upgradable and if so, what is the max processor speed that the motherboard will accept?
Harry_> The processor on a Notebook computer is integrated with the motherboard and cannot be upgraded.
dan> do you have a part number for that motherboard??
Harry_> The information you have requested is an unpublished specification.
Harry_> The hardware (e.g. motherboard, hard drive, video graphic chipset) used in our products are custom designed and built specifically for Sony as OEM hardware from various selected manufacturers.


Your motherboard is a PCG-8M2L. It should have a similar number on the bottom of your unit if you want to verify this. In checking suppliers for this board I found it is sold "without" processor. Therefore it can not be "integrated" to the motherboard. Now maybe his term of integrated meant "matched", but, after I tested him by asking for the part number his answer led me to believe that he was not being very honest. So don't trust Sony if you call them looking for the answer. Any answer to why they "wont" give you this upgrade data is an evasive tactic and not a good business practice.

I would suggest:
Go to Powerleap and click on the "Powerleap online upgrade configurator". If your firewall gives you an active X warning click "accept". This will evaluate your entire hardware setup and give you a report on your machine and available upgrades of all the hardware items in your machine. On the report to the left are catagories. Click on the processor one. It should list acceptable CPU's. If it does not, they have an online chat at the bottom where an assistant will give you a list of upgrades. Give them the motherboard part number above, it will expedite their answer. Online chat is only available 7am to 5pm EST. I'm not recommending this site for a purchase, just an info source.

Cool, thanks. I will check that out. One followup question: In general,
is it possible to put a Pentium M on any motherboard that supports
Pentium 4? Are ther any upgrade caveats I should know about?
