Celeron to P4 upgrade, need help!

Is it just cache or is there more to it. I'm upgrading my laptop from a 2.0Ghz Celeron to a P4 of 2.2 or 2.4 depending what I can find and I was wondering what the actual difference in the chips is.
Also, the chip I've got in mine looks similar to this
But there are some that look like this

My question is: can the cover thing be taken off? If so, would it then look the same as the one I have. I only ask this because the cooler on my laptop seems to be designed for chips without the cover.

hope you can help

cheers

I've done swaps both ways with notebooks, and most of the time there is no problem. Make sure to use a thick, nonconductive thermal transfer compound. There are also some thermal transfer pads that you can use to raise the contact area a fraction.
 
can the metal cover be taken off or do I have to re work the heatsink to fit? At the moment there seems to be some kind of aluminum foil that is used as the main transfer compound but that only suits the small core only chips rather than the ones with the cover.

please help know what to do, can I buy a chip with a cover and then take it off or are the cores actually made differently when they are protected by the cover thing (BTW what is that called?)

It's possible, but I don't recommend taking the IHS off (Integrated Heat Spreader, btw).

The mobile P4-based celerons are typically totally interchangable, if you sit both cpus on a flat surface, they are very very very close in height/clearance. This is why just making a shim and using a moderate amount of thick, non-conductive thermal transfer compound almost always does the trick.
 
I'd suggest finding a mobile specific P4. You get the performance plus a bit of power savings. The mobile chips lack the IHS. I wouldn't recommend modding a desktop chip by removing the IHS - the notebook still may not like it because the mobile P4 runs at 1.3v and the desktop chips runs at around 1.5v give or take depending on model.
 
i would suggest getting the mobile P4 chip that doesnt have the heat spreader on it, they are up to i believe the 2.6ghz, but the 2.6ghz costs ALOT, just like the 3.06 533mhz bus northwood still costs a decent amount. I had a sony PCG-GRT laptop and the processor in it was a P4 and did not have the heat spreater on it, and i tried to put a faster mobile P4 that did have the heat spreader, and it wouldnt work.
 
thanks everyone, i went for a 2.2ghz p4 m. It runs at 1.3v and is also a northwood (like my celeron) so fingers crossed!!! Along with an extra 512MB of RAM it should be a decent upgrade.

cheers
