Elitebook 8770W Missing GPU - How to enable Intel HD

[SEAS89]

This may be an unusual request...

I came across an Elitebook 8770W at the office that someone had bought and I think removed the nVidia K5000M GPU that was in it.  It had never been started up either.  I booted it and it went through setup and it works for the most part - but none of the external graphics (DisplayPort/VGA) ports work and the driver that loads is "generic vga" by Microsoft. 

I run speccy and it says it has a GT216 GPU and the nVidia GPU identifier says it has a NVS 3100M.  Not sure either of these are right - and in any case I can't find an HP/nVidia driver that will load and the performance tool rate graphics as a 1.0.

I'd like to enable the Intel HD4000 graphics and get a driver for that.  Speccy says the CPU is an i-7 3740QM so i think it should have that built in GPU, right ? 

Is there a switch on the motherboard or something in the BIOS or am looking in the worng place for the drivers ?

Thanks, tried it but still get the "graphics driver could not find compatible hardware".

And, that appears to be an nVidia driver install.  Is it possible to install and use the built-in Intel HD4000 graphics ?  I tried downloading that set from Intel but it also says that the "system does no meet minimum requirements"

In device manager it still says generic VGA

I believe it's not possible to activate the built-in Intel HD 4000 graphics. My EliteBook 8770w is equiped with Intel Core i7-3720QM, which is also supposed to have Intel HD 4000, but for some reasons it is disabled.

I couldn't find a way to activate it or at least an explanation why HP has disable it?!
