I have a laptop packard bell f5280 with a celeron 2.8 ghz processor. I want to upgrade to a pentium 4 . The only doubt I have is whether the power difference will cause any problems. The celeron ran on 64 w the pentium will run on 103w . has anyone experince of a successfull conversion of this type? will this cause problems? overheating?
any advice would be appreciated
at the moment my CPU runs at 100% a lot of the time and can be a bit slow. the front bus speed is 400 and it has a cache of 128k . I am hoping that with a pentium 4 that has afront bus speed of 800 and a 1MB cache I will have better performance

According to the following review, it may be more appropriate to call your laptop a "craptop"...lol

I have a feeling you're looking at desktop CPU's rather than mobile CPU's. The fastest P4-M's or Pentium-M's run at 533MHz FSB:

"I am hoping that with a pentium 4 that has afront bus speed of 800 and a 1MB cache I will have better performance"
The 128K Northwood Celerons were the most worthless pieces of crap to ever roll out of Intel. A P4 running at the same clock speed would be around 2x faster (and even faster in certain "branchy" applications).
You'll just have to make sure that your motherboard supports the Prescott core P4 and an 800MHz FSB. Since it's a laptop, the board and/or battery may not support the high current draw of the Prescott, and the cooling system may not dissipate the heat quickly enough.
If it supports an 800MHz FSB, however, you could always try a Northwood P4--they're available at up to 3.4GHz. Despite having only 512K of cache, they're slightly faster clock for clock than the Prescott. They also consume less power and run much cooler than Prescott.

I know the pentium 4 I am looking at is a desktop. so is the celeron I have at the moment. The performance of the pentium 4 is what the mother board will cope with. but the wattage may be an issue.

Yes but I would doubt it supports 533 or 800fsb, may not even support some P4's!!
Good luck..................

unless you are running somthing to cause this, I would suggest something else is going on. I have XP on a IBM thinkpad with a P2 366 & 288mb of ram and, the cpu doesn't run at 100% a lot of the time.larry
