Hi, I have a HP laptop dv9740us with a T5450 CPU. with a HP 461069-001 INTE CPU DV6700 DV9700 Series Motherboard

I bought a new CPU (Intel Core 2 Duo T9400 2.53GHz 6MB L2 Cache Socket P 35W) and installed it.

After I booted up my PC, it just stays on with a black screen.
I can hear the fan working and other lights on, but nothing on the screen...

Help please...

Email HP support and ask them if the T9400 is supported, they are usually very good at supplying that info. I don't think it will be.

Kinda late now, but thanks a lot! lol. CPU was not supported by motherboard even though HP themselves told me that it was...

That's often the issue with trying to upgrade laptops and OEM PC's, it turns into a trial and error experiment.
