Celeron to P4 upgrade, need help..

[parkie]

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 in the top image. I only ask this because the cooler on my laptop seems to be designed for chips without the cover.

hope you can help

cheers

OK, I had a 2.2Ghz Pentium 4-M C1 SL6J5 arrive today and so I installed it instantly. The problem is that the Laptop Motherboard will only run it at 1.2Ghz. It recognizes it in the bios as the correct CPU but will only run it at it's power saving speed (1.2Ghz). Anyone know why this would happen?
