| 445269 | 2006-04-09 22:08:00 | hi everone this is my first post here - :help: i took a look but iam not sure if any one has appempted to replace a pentium 4 mobile with a pentium m in there laptops or if its even possiable/compatiable i have seen pentium m and pentium 4 mobile with the same specs for example pentium 4 m with 400 fsb at 1.6 GHz 512 cache socket 478* pentium m with 400 fsb at 1.6 GHz 1 Mb cashe socket 478* the laptops i have are an ibm thinkpad A31 with the pentium 4 m and a compaq presario 2538cl with a pentium 4. i would apprceate any help/information to the question * its because iam not so sure about the socket ( i know that the desktop p4 are 478 and some pM are 479) but what the P4 mobile is i dont know thanks alot :thumbs: |

| 445270 | 2006-04-10 00:02:00 | Problem with some laptops is that SOMETIMES some cpu's are soldered directly onto the motherboard. (My old lappie did) Then theres the issues of finding the right service manuals on how to open the laptops innards and closing it back up again. With components that small its quite a tricky thing to do. |

| 445271 | 2006-04-10 01:17:00 | Its doable, but it will require some research and there noway to be 100% sure it'll work. You need to check chipsets and memory interfaces to make sure they're compatiable, make sure the laptop can handle the thermal output, and can supply suffecient power. | Pete O'Neil (6584) | ||
| 445272 | 2006-04-10 02:48:00 | this is replay to the posts my cpu is not soldered on and i think i will be able to preform the task of replacing the proccesor with little or no problem, but i dont want to invest in the proccesor if its not compatiable . the output temperature of the pentium M is much lower than the pentium 4-M and very thing else about the two proccesors seems very simular however the pentium M posses a cash that is two to four time greater then the pentium 4-M . now is the chipset i have compatiable iam not sure i dont even know what it is - it should be a intel chip . please tell if u need more information to asses the system compatiablity thanks |

| 445273 | 2006-04-10 05:31:00 | please tell if u need more information to asses the system compatiablity thanks Perhaps you could do a little research for yourself? There is nobody in this forum that would know off the top of their head whether your upgrade is possible. Anyone who answer you querrie would have to do research to answer the question fully, im sure you must be capable of a lil research? You'll need to find out what chipset your laptop uses and then check the intel website to find out if the Pentium M is compatiable with this chipset. Also the Pentium4 M's use a much higher voltage than the Pentium M, if that same voltage is provided to a Pentium M then it'll blow up. You'll need to find out if you can lower the Vcore on the laptop aswell. |

| 445274 | 2006-04-10 05:41:00 | The only thing I've heard of is by ASUS. BUT this is for desktops not laptops. Which is an adapter (www.behardware.com) which lets u do this. BUT this also needed a BIOS update. |

| 445275 | 2006-04-10 05:42:00 | Laptops are designed and built as a unit. About the only "enhancement" that's encouraged is adding memory. If the CPUs use different voltages, it's unlikely that there's an adjustment. Is there such an huge performance improvement and would it be worth the cost, and the risk? I don't like opening up laptops. ;) |

| 445276 | 2006-04-10 06:46:00 | i did the research and i have a 845mp/mz chip set - however it doesnt look like the mother board accepts M proccesor - but i waiting for a repily form intel - its very funny because the thinkpad t40 which has all most all the same fetures runs on the pentium M, ok thanks alot stay positive :) |

| 445277 | 2006-04-10 06:52:00 | ... its very funny because the thinkpad t40 which has all most all the same fetures runs on the pentium M, Exactly, they are different models. Each designed as a unit. ;) |

| 445278 | 2006-04-10 07:54:00 | IMO it would be a waste of time replacing your existing processor for another one of very similiar specs but just a bit more cache. Go for a new laptop alltogether and maybe with dual core or 64bit. | E|im (87) | ||
