    Hi there. I bought an HP ze4910us laptop and I love the thing except the processor.. Its a Celeron M 1.4ghz. I can deal with it for gaming now but in about 6 months to a year I would like to upgrade it to maybe a 2.2ghz.. is it possible to change out the processor? and if so which would u recommend I put it there for performance and what should I do to control the heat?

    considering the highest P-M is a 2.133ghz..... It varies from laptop to laptop, some are soldered in and others like mine are just under a cover.

    From what I can figure out the Celeron M 1.4ghz is a socket 467.. Which limits me to Celerons and a few Pentiums.. I was just wondering if anyone knew whether it is soldered into my notebook and if not will my notebook overheat with a new chip

    A pentium M is actually cooler, on average. Same at max. Other than that, you should be able to put at least what the highest build-to-order option is. Search around for a service manual. With my Dell, it is very easy to follow and outlines replacing everything with nice pictures and step by step ease.

    so is it possible to put a pentium 2.4ghz in the laptop and not have the notebook consantly over heat? i'll be pluged in to a wall about 95% of the time i use it so i'm not worried about power drain, just that the chip wont over heat or anything like that. right now i'm running a celeron M 1.4 ghz

    Swapping a CPU within a manufacturer family series (PM1.4 to 1.7, Banias to Dothan for example) is challanging enough patching the bios to get it to even work. Forget swapping from one chip design to another entirely.

    But if they have the same socket they would be able to be swapped right? so if i was to buy the Pentium 4 3.0ghz and swap if with me celeron M 1.4ghz would my Bios automatically change its settings to compensate for the new chip or would i have to do this manually? and if that chip wouldn;t work, would a celeron 340/2.93ghz?

    Fooling around with the bios (other than official update) is a sure way to turn your laptop into door stop. What you want to do is impossible at less than super-human levels. Go to TabletPCBuzz.com and check Toshiba forum to get an understanding of what is involved just to switch within a processor family, much less across designs entirely.

    well if upgrading the processor isn't a good option then what would be my best bang for the buck upgrade? i'm looking to improve it for video and gaming.. it has 512 pc2100 ddram and a 60 gb 4200/rpm hd.. should i upgrade these first or should i find out if there is someone in town that can do the processor upgrade?

    Not sure if this was stated.
    Although both the Pentium M and Pentium 4 use S478, they use completely different pin designs. so any P4 processor would not work on a PM system. More than likely it would fry the cpu and/or the motherboard. Shop around for a faster PM, extra memory, and a faster HDD.

    So then would I be able to swap out the celeron M 330/1.4ghz for one of the higher end Pentium M chips?

    Hi Jeff,
    You won't be able to put a Pentium M into a notebook that had a Celeron M in it. You cannot change between different CPU designs, even if the the number of pins are the same or the CPU fits in the socket. This is because, like mentioned earlier, the pin out is different. ie. what was a power pin in one design may now a ground pin for the new CPU. Your only chance for a CPU upgrade is a faster celeron M. For the best bang for the buck performance increase, I would get a 60GB 7200rpm Hitachi hard drive, that will speed things up a great deal over your 4200 rpm drive. Also a free thing to do to increase performance is to go to my post on optimizing your notebook for speed.

    good luck

    ok so basicly my only option would be to upgrade to a celeron M 1.5gz with 1m cache.. which isn't really worth it.. so for gaming would upgrading the HD or 1gb or pc2700 get more performance out of my machine.. i understand my laptop isn't the best for gaming but i do want games to be somewhat playable and not laggy
