CPU upgrade - compatibility advice

I have an ASUS K501E which has a Pentium T4400 in it.

I also have a Intel Core 2 Duo T9400 CPU that I'd like to replace the Pentium CPU with.

From the research I've done, I'm pretty sure that the T9400 is compatible with my machine, but then again, I'm no expert.

Can anyone clarify this for me please.

My laptop has an NVIDIA MCP79 chipset.
The BIOS manufacturer is American Megatrends. BIOS date: 01/12/10. BIOS version: 207.
 
I see the forum at Notebook Review told you the proposed CPU upgrade is fine. If this (K50IE is your model then it suggests that..

Intel® Core™2 Duo Processor P8800/P8700/P7450/T6670/T6570/T5900 : 2.66 GHz - 2.2 GHz,
Intel® Pentium® Dual Core Processor T4400 : 2.2 GHz
Intel® Celeron® Processor T3100 : 1.9 GHz

...the range of CPU's are a little lower specced. Might be an idea to join Asus Forums and get a definitive answer. The MCP79 seems to compatible with T9xxx CPU's, but a lot will depend on the laptops BIOS.
