Currently, I have a notebook which is using a Core Duo T2250 (1.73Ghz, 533 Mhz FSB) on the chipset 945GM and an integrated Intel VGA 950. I want to upgrade the current CPU to a higher CPU and I want it to be a Core 2 Duo. What CPUs can I choose for the upgrade? Thanks all

A concise, practical checklist for whether a laptop CPU swap to a different mobile family is feasible — and how to do it safely. Since already posted hardware-identification output and other members (, , , ) suggested vendor support and hands-on experience, the following focuses on the compatibility gates that matter most (firmware, electrical, and thermal), plus a safe test workflow.

Practical checklist:

  • Confirm physical removability and exact platform ID. The service manual or a photographed teardown of the cooling assembly will show the retention style (socket vs solder) and the board’s FRU/service numbers. Handle the board with ESD precautions and battery removed.
  • Get the OEM CPU-compatibility list or service manual from technical support; ask specifically for supported mobile CPU families and BIOS notes. Community reports for the exact service number are valuable if the vendor list is missing.
  • Check BIOS microcode and whitelist behavior. Update to the newest BIOS before attempting a swap; unsupported processors often cause a no-POST condition rather than a clean error.
  • Verify chipset/FSB, required core voltage and VRM capability, and TDP. If a candidate CPU needs higher power or different voltage rails than the board provides, it will be unstable or fail to boot even if the socket fits.
  • Cooling capacity: compare TDPs and plan for thermal paste, proper heatsink seating, and testing under load while monitoring temperatures.

Common failure modes and recovery steps: if a swap yields no POST, re-install the original CPU, reset CMOS, and re-flash BIOS. Modded BIOSes that add microcode exist but carry risk and warranty loss. Keep the original processor and document each disassembly step (photos, screw bins).

When an upgrade is impractical, swapping to faster storage, adding RAM, or OS tuning often gives a bigger real-world boost with less risk.

upgrading cpu in your laptop is quite a hard stuff, normally manufacturer they never give the manual for your mobo.. unlike buying a mobo for a desktop in which they will give you a manual or a guide and from their you can tell the limitation of your mobo...

Maybe you think that the CPU is soldered to the board, it cannot be repalaced but on youtube.com, there are many clips which perform the CPU replacement. I enter this forum to look for a real experience on CPU replacement. Thanks for the answer.

the cpus aren't soldered onto the motherboards, i've replaced SEVERAL laptop cpus before, it's actually pretty easy.. once you get to them alls you need is a flathead screwdriver to unlock the CPU.

there are alot of things you need to find out.. what kind of notebook is it? What cpu socket is in there? Have you tried contacting the laptops manufacturer's tech support to maybe pull some information from them *make sure you talk to a TECH*

let me know how you make out..

maybe you could post your laptops make and model number

Yeah, my laptop is 5572ANWXMi of the Series 5570, using the Core Duo 1.73 Ghz, 533 Mhz FSB on the chipset i945GM (shown by CPU-z). I think, it used socket M, right? (CPU-z shows socket 479mPGA). In your opinion, what core 2 duo can I use to upgrade?

you just ask to a hardware shop
cos mat be the core u due processor donot support ur current mother board especially LapTop

all the best

yup, some cpu are soldered on the board..but there are cpu's that can be replaced..my point is you cannot just anyhow upgrade the processor of your laptop.. motherboard are designed for specific limitation's.. it will be costly if you upgrade it but your motherboard cannot support..

try what Caperjack has suggested e-mail your manufacturer and ask them the maximum processor speed that your motherboard can support... :)
