Don't think so - your laptop runs on a 533MHz (4x133) FSB and not at 400Mhz (4x100) FSB like the Banias core cpu.

According to the thread:

All R52 models with a Pentium M have the 915GM/PM chipset @533MHz bus.

and then, according to the thread:

The upgrade to a Dothan 725A 1.6GHz CPU was quick and works perfectly. CPU-Z shows the voltage adjustments are correct and SpeedStep is working properly.

Note: The CPU I used was a 400MHz bus Dothan. I do not have a 533MHz bus Dothan to test with at this time, but would like to find out if those are properly set up by the BIOS. When I get one, I will test.

which seems to indicate that this 400 MHz FSB Banias will work in the Celeron-R52.

Wow ^ didnt know that - I figured that as soon as you pop in a Pentium Mobile it would increase the clock to 133.

It will work. I remember Kyocera doing it on one of his R52 machines.

Good memory in your system (and still running at good speed!), George

- I guess it could be the one mentioned in the thread:

Original description: Based on 1858-22U: Celeron M 370 (1.5 GHz) (remaining description snipped)

The above description is from the Lenovo product page, however, I have done some upgrades:
