Windows 7: Devices Error

27 Oct 2009   #1

Windows 7 Ultimate
Devices Error

Since installing Windows 7 Ultimate, Devices has been showing my laptop icon with the yellow triangle/exclamation mark symbol next to it.

When I right click and go to Properties > Hardware the first entry is Unknown Device and it shows the same warning symbol.

The right click drop-down box's Troubleshoot, just above Properties, also has this warning symbol next to it but when I run Troubleshoot it is unable to fix the problem.

Device Manager shows Other Devices > Unknown Device, again with the yellow triangle/exclamation mark.

Right clicking Unknown Device and going to Properties > Details > Hardware IDs shows ACPI/HPQ0006 and on the second line *HPQ0006

I have uninstalled it via Device Manager but it just re-installs when I re-boot and I am back to square one!

My laptop is a Compaq Presario C350EA with Windows 7, 32-bit, installed and as far as I can tell, it is working OK but I am a little concerned about these warning symbols.

I would be grateful for any ideas and/or suggestions.

Hey Tiber, if I'm looking at this right, that may be the driver for the quick launch buttons, but I don't know unless you can add some more information from the Hardware IDs tab.

Try going to and downloading the latest drivers for your computer.

Thanks Zen00!

The HP site only has XP and Vista drivers at the moment. Having previously run XP I thought I'd try the XP Quick Start Buttons. I got an "incompatible ..." message but the yellow triangles and exclamation marks have all gone so that will do for now.

Presumably HP will have Windows 7 drivers available eventually.

Thanks again, excellent reply. Much appreciated.

They may not have Windows 7 drivers, but Vista drivers should be more compatible.
