Windows 7 - No Display & base system device drivers missing on my HP DV9000 laptop

Hi All,

This morning my HP DV 9000 laptop screen comes up grey with no discerning images. I have an additional monitor attached (for TV) and booted into safe mode with networking and can see the desktop in VGA on separate monitor only.

Looking in Device MGR I have two 'base system devices that need attention. They are not identified as to what they are only PCI Bus 7 device 5 function 3 & PCI bus 7 device 5 function 2. I have no idea where to start with this? Anybody?

Win 7 Prem Home 32 bit SP1
Intel 5500 @ 1.66ghz
2GB ram
NVIDIA geoforce 7600

Last night - everything ran fine. Read newspaper online & watch TV on separate monitor. Everything closed down without issue.

Some laptops have the option of outputting the display signal to LCD, VGA or Both.
I'm not sure that you have those options, but it's worth checking out in the BIOS.
There's also the possibility that your LCD backlight may have gone out and needs to be replaced.
