Upgrading the to a pentium processor on an Esprimo V6535

My daughter was given the above laptop. It is currently fitted with a Celeron Processor socket P. The specs indicate it came with various processors below
Intel® Pentium® processor T4400 (2.2 GHz, 1 MB, 800 MHz)
Intel® Pentium® processor T4300 (2.1 GHz, 1 MB, 800 MHz)
Intel® Pentium® processor T4200 (2.0 GHz, 1 MB, 800 MHz)
Intel® Pentium® processor T3400 (2.16 GHz, 1 MB, 667 MHz)
Intel® Celeron® processor T3100 (1.9 GHz, 1 MB, 800 MHz)
Intel® Celeron® processor T3000 (1.8 GHz, 1 MB, 800 MHz)
Intel® Celeron® processor T1700 (1.83 GHz, 1 MB, 667 MHz)
Intel® Celeron® processor 900 (2.2 GHz, 1 MB, 800 MHz)
Intel® Celeron® processor 585 (2.16 GHz, 1 MB, 667 MHz)

I would like to upgrade it to one of the pentium processors these can be got from ebay, I am finding it difficult to be sure which of the many Pentium processors would be suitable. I have checked inside and it is easily upgradeable. The Fujitsu website doesn't go into enough detail
specific Intel Part numbers would be helpful. I am confident in doing the upgrade include a BIOS update if necessary

Intel Celeron M [email protected]
code name Merom
Socket P (478)
Core speed 2161.3 MHz Multiplier x13
Bus Speed 166.3MHz Rated FSB 665MHz

What chipset does this laptop use?

 

Intel GL40

 

These are your chipset specs
Mobile Intel® GL40 Express Chipset

I would stick to a processor with the same BUS/Core ratio which is 667mhz.

By the way this is a thread that you may find interesting.

I tried a T7300 CPU on a V6535 laptop (V1.22 BIOS) and it works perfectly fine. My guess is that the V6535 is compatible with all the Merom based CPUs. Hope that this info will be of some use for those who are trying to get a cheap upgrade.
