    Hi

    I have a Compaq Presario c307nr laptop. It came stock with a T1350 cpu and I am trying to upgrade to a T2350 duo core. Both chips are the same socket. If you look at the specs they are almost identical, the only difference is the T2350 has two cores. My board is a 30C6, my chip set is i945gm which supports the upgrade, by bios version is F.24

    I have installed the cpu but the computer will not boot. Power light just flashes none stop. So i took the cpu out and put the original back in just to make sure I didn't screw something up and it boots no problem. So I don't know if someone out there knows of a way to make this work. Any advice would be greatly appreciated. Thank you

    Are you sure you fitted the cpu correctly ? Cpu's are very delicate things and it sounds to me as if you may have a faulty one. :(

    I tried to install three different times with the same results. The chip itself looks in perfect condition. I did buy it used but was told it was pulled from a working comp.

    Sounds very likely that the cpu is fried.

    I guess that is a good possibility. But I am also starting to think that my bios just cant handle it. I will have to see if I can get my hands on another chip.

    As your mobo / chipset supports that cpu i doubt this is bios related, im not saying it isnt..... just my opinion. Check your mobo manufacturers website for a cpu support list.
    Personally a cpu is one item i would not buy second hand, you have no guarantee of the quality of the cpu , how its been handled etc. It only takes a small static discharge to fry a cpu and is suspect this may have happened in your case.

    Yeah I try not to buy second hand but I got that chip and a amd athlon xp 2200+ that I needed for my old desktop for $20. So I thought was worth the risk. The amd runs fine so not a total loss. :) Also being an older cpu it is kinda hard to find new.

    If you are sure the cpu is ok, and in addition the mobo must provide the correct voltage, current, multiplier and power for it to work. Are you sure the mobo can adjust for yours??? Laptops are built not for DIYs and don't expect you change hardware because of a lot of reasons. You better check with the official specs!!! If it says so, it should be your cpu problem.

    On a separate note, hopefully you haven't damaged the T2350, you may get your $20 back through selling it (and you'd be ahead due to the other CPU).

    Unfortunately, it looks like the CPU you have is the fastest that you can use with the older Socket P.

    I don't know about wikipedia but according to hp, intel and cpu world the T1350 is a socket M. I just found out through the hp forums that the T2350 is just not supported by my bios. According to them I can upgrade to a T5500. I dont quite understand how but my bios only supports the t1350 and the t5500. I can't really complain though, thats even more of a jump than I was hoping for.

    According to Wikipedia again! the T5500 is a massive jump over the T1350, afterall its a Core 2 processor not a core processor!

    Just make sure you get the right type, it seems the processors in the T5xxx range are available in Socket M, Socket P, and FCBGA (the new ball grid array instead of using pins).

    What type of socket does your cpu have currently? is it pins, is it balls (aka the cpu back is practically flat with no pins), what socket does it say alongside where the CPU goes in? thats the safest bet!

    I was just looking at the service manual for my laptop. according to hp the t1350 isn't supported by my computer.
    this is the list of cpus that my model laptop came stock with. Notice the T1350 is not listed and thats what it came with.
    I don't think HP knows what the hell their doing.

    Intel Celeron 430 1.73-GHz
    Intel Celeron 420 1.60-GHz
    Intel Core Duo T2250 1.73-GHz
    Intel Core Duo T2300 1.60-GHz
    Intel Core Duo T2050 1.60-GHz
    Intel Core Duo T1400 1.83-GHz

    Try removing (for at least 10 seconds) and replacing the cmos battery prior to installing the new chip.
