The one you ordered did not work for several reasons. The Bios has to recognize it. That is why you need to stay with the HP list, They wrote the BIOS. The wrong FSB, Possibly the wrong voltage supplied to it, etc.
The latest BIOS is the latest BIOS. It has to come from HP so if you have the latest that is all there is.
Do not go by Speed of the CPU and FSB.
The CPU has to match, for example since it lists a T8100 a T8100 will work, A different processor with the same Ghz and FSB will not work.
it shows a Penryn, 800MHz front side bus, 3MB Level-2 cache per core will work anything else with that speed and specs is unlikely to work.
This is what makes upgrading a laptop tough.
If you could find this one
it would work. For example this listing from ebay
gives some for sale.This one
came up when I searched for the penryn 2.4Ghz, However I question why it didn't show as a T8300 in the HP list of what will work.Please Note:
I do not buy from ebay and do not know if these sellers are good or bad.
The Passmark CPU benchmark
shows the T8100 at 1332 and the T8300 at 1524
A T2310 (533 FSB) Shows as 771 and a T230 shows as 791. Notice that the higher the Txxxx number the faster.
