After installing out corporate base image on this laptop, getting additional support drivers has been a nightmare. The base image is currently a 64 bit Windows 7 Enterprise installation, and while I could download drivers from the HP website, most of them wouldn't install, even when I could get them on to a notebook with no Wired, WiFi, Bluetooth, USB or memory card devices recognised.
I believe it was a BIOS update which got Windows to recognise the correct processor, and allow the chipset, bluetooth, WiFi, Ethernet and, crucially, USB drivers to go on. But after a week of testing and retrying different tactics, I'd given up most of the "best practices" style "try one driver only, reboot, note any changes before trying anything else", and was wildly throwing driver installs at it from HP and the devices / chips manufacturers.
Once everything seemed to work (except TPM, which still isn't recognised) I was way over schedule for delivering this device to it's end user and I presented it as having been a pain, but working okay now.
It has come back because as soon as you plug it in to a projector, nothing happens, and there's no way to switch to, mirror or extend the display to the projector on the VGA line. In testing, I can actually get an unusable, garbled image on the external display, if I plug it in before booting the notebook, and sacrifice any display on the built-in panel.
I attribute this to Microsofts' default VGA driver which it is still running on.
The recommended Intel Graphics download from HP for this device, and this OS is SP72651 (as far as I can tell) and running that only produces a message stating "This computer does not meet the minimun requirements for installing the software."
Attempting to find drivers for an Intel 3825U APU Graphics from Intel only leads me to Intels automatic driver update software, which also tells me that I don't have any supported devices in this Notebook. The instructions they give for manually downloading a driver, in the event that the updater doesn't work for me, tell me to look for a "Quick link" which doesn't exist, saying "Previously known as..." and getting the driver under the development code name for that processor.
How can I resolve this?
