Hello there!
I'm having problem with my HP probook 6550b Laptop , I just downloaded and installed all drivers from hp support website and everything works just fine except for the graphics crad, It's showing up as "Unknown Device" in the Device Manager, And when I try to Install the ATI M93S3-B Video Driver, The installation doesn't detect it and therefore it doesn't complete, Please help
I've had this problem with my other HP laptop and I solved it by Updating the BIOS, But it didn't do the trick this time
Solved! Go to Solution.

What is the exact product number of your laptop?
I assume your laptop Intel processor?
Have you already installed Intel chipset driver?
Does it come with dedicated graphics chip?
What are the hardware IDs of the missing drivers (yellow exclamation marks)?
