Pavilion DV3 4060es CPU upgrade

[sregojo]

I have tried to upgrade the laptop (pavilion dv3 4060es) cpu from i3 350M to i7 740QM.

When I plug the processor I get no video.

I have the latest bios intalled (F.23, march 2016)

The service manual indicates the i7 740QM as a compatible processor.

Is it a compatible processor?.

Do I have to configure something in BIOS before upgrade?

No you made a very common error. You can't just look at the list of processors and assume any one of the processors will work in all versions of that model series. Look at page 17 of the manual. The different system boards are listed as follows:

For use only with Intel Core Quad processors 611348-001

For use only with Intel Core Dual and Core2 processors 599414-001

For use only with Intel Core Quad processors (1-GB) 622627-001

For use only with Intel Core Dual and Core2 processors 622626-001

So in order to install a Quad processor you need a Quad motherboard. The fan and heatsink is the same. HP no longer has the boards in stock so you would need to find one on eBay or contact an HP reseller:

I took a quick look and came up empty but a little harder search might turn up something.

Thank you for your response.

Taking into account what you said, I guess a "Dual Core i5-580M" could work in my motherboard. doesnt it?

Yes you can install any of the dual cores
