Can i upgrade the CPU on a pre built Notebook?

[Trollhunter]

I wonder if i can take out my celeron 1.7 and replace it with a P4.
I have a Compaq pressario 2100US.

Sorry for this noob question on notebooks

It all depends on how the chip is in there, some laptops have the cpu soldered on to the motherboard. I could not find anything specific in my quick search. sorry.

you could open the laptop up and see? i had a inspiron 2200 that had a celeron M that was upgraded to a 2ghz dothan. awesome if you ask me! ;)

if it is a p4 laptop then it will come with a zif socket usually located at the bottom for ease of use and service then remove the heat sink and you can then replace the cpu with the better one!!!

doesn't SiSoft Sandra tell you if your CPU is upgradable? I think it does, that's how I found out that my Dell Latitude C640 with 1.7 GHz can support up to 2.4 GHz

I think most of today's newer notebook allows you to upgrade the cpu, the question is how long will that effect the battery life as well as cooling solution. The truth is that it may not worth that much to upgrade the cpu as the cpu alone might cost you around 100ish or more but if you look online you can actually buy a new laptop for around 500-600 or even 700 for the pentium M laptop, maybe you can consider sell your laptop and upgrade to a new system.
