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

Thx
