Hi:

Below is the link to the service manual for your notebook.

According to chapter 1, the best processor you can install would be the T5670.

Theoretically, your notebook could support the T9300 or T9500, but your notebook's BIOS has to have the microcode to support those processors.

I checked the BIOS updates on the support page, and none of them add support for different processors.

I see that you already have the last BIOS update offered (F.20), so that is good.

So, if a T9500 is not too expensive, you can experiment with one and let us know the results.

h i knoe thanks i actually saw a blog and someone put a t9300 and 8 gigs of ram (i know 4 is the max) so i was wondering if i can put a t9500 bc its almost the same in (TDP and bus speed)

You're very welcome.

if the T9300 worked, then the T9500 should work too.
