I have a compaq presario 900 laptop with a Mobile amd athlon xp 1500+ 1.33ghz....Does anybody know how to find out if I could upgrade the processor without Frying the motherboard?? It would be cheaper than Buying a new laptop...Keep in mind I know quite a bit about computers...just have never upgraded a processor....So if you know how big of a processor it can handle and maybe a site that sells the processor would be appreciated..Thanks

    The processor you mentioned is not what is specified for this model..

    As for upgrading to a faster CPU..unless it has a ZIF (zero insertion force) socket.. then you are going to mess with several HUNDRED pins in soldering a solid connection.

    I would advise not to, for one.. you violate the warranty, secondly it may not be possible as the CPU is soldered on the motherboard.

    You will not gain any noticeable performance by a cpu upgrade. Add more RAM for better performance, otherwise, save your money for a new platform.

    It looks like someone else has installed a 2500+.  Check out the thread and I reccommend you just do a search on for the chip you need.  If it were me I would be sure to get the exact same chip that someone else has already successfully installed.  Exact Same....

    95% of compaq laptops not upgradable.  Next time buy a laptop with replaceable CPU and with free RAM slots.  Remember, almost all laptop makers "max out" their systems when they sell them, which means you cant upgrade them.  Sell it on EBay and buy a truly upgradeable one, not a Compaq.  But check carefully before you buy next one, see if it can be upgraded in CPU or RAM.  Good luck !
