Preboot authentication no pointing device support - EliteBook 840 G5 DE 7.2.8.4

[ricardo_manca]

Hi

We currently have the HP EliteBook 840 G5 with Windows 10 1803. Currently running software encryption for hard drives and version 7.2.8.4

With Preboot enabled we can only make use of the keyboard, and not the touchpad, pointer, or external mouse. In order to go through the Recovery process we have to make use of the TAB key to navigate around. Bios version was 1.00.05 and was upgraded to 1.07.00 which is the newest version available from HP. In addition, I've installed the Synaptic drivers SP95505 and HP Pointing drivers SP94796 which didn't resolve the issue.

Could you check if you have enabled the following option in DE policy?
Drive Encryption 7.2.8 > Product Settings > your_policy > Boot Options: Always enable pre-boot USB support
Does it solve your problem?

Hi

McAfee support called me back about this issue, and I now have a solution. In the Boot Options tab Fast Boot is enabled by default and prevents the laptop from loading the onboard Touchpad drivers. With Fast Boot disabled the Touchpad starts working.

Hi Ricardo, are you speaking about the Boot Options in BIOS of the laptop or in the DE Product Settings policy? We are facing the same issue on HP 850 G5 laptops. I do not see any fast boot options in ePO for the DE Product Settings policy.

Hi markgarza The Fast boot option is in the BIOS. F10 to access the BIOS Switch to the Advanced tab Select Boot Options Remove the check next to Fast Boot Hope this helps!

Thank you! And you have the Always enable pre-boot UBSB support option enabled in your DE policy, correct?

Hi Markgarza The Pre-boot USB support will only provide the assistance needed for environments that have preboot enabled, or recovery for systems when pre-boot is enabled from too many failed logons for older laptop computers. You still require fast boot disabled on newer model laptop computers to allow for USB driver support after post. The WindowsPE Emergency decryption doesn't care as to policies you have in place, and requires Fast Boot to be turned off as it is a standalone environment. You could build a stand-alone WindowsPE image with GUI support, drivers, etc..., but I personally haven't had time to go down that route. I'm using the McAfee software they built to generate WinPE USB images which is available on their site. Hope this help!
