From this ticket, I'm awared there are many HP platforms shared this issue.
Here is the platform list I found here: 1. HP ZBook Studio G5 by Marcin [1] 2. a HP Elite Dragonfly by Michael 3. a HP Elitebook X360 1040 by Nova [2] If you could help to find your machines on the Ubuntu certification page[3] then it will help (please also share if any component is different). Back to this issue, we did face this issue during the certification on some HP machines and as the comment#19,20, it's also HP told us the way to workaround this issue. FWIK, this issue is caused by HP's firmware. HP has a windows application which will configure the HP EC (embedded controller) as a something like Windows mode. In this mode, EC will send the different keycode when you pressed the function key. After pressing the power button roughly 15 seconds, it will reset EC to something like default(normal?) mode which working good in Linux. That's why it impacts the dual boot users as you reported. For comment#24, we communicated with HP many times and would like to ask HP to provide the detailed specification of what HP did in Windows then we could implement it in Linux as well but unfortunately, HP didn't provide further information and announced the issue is fixed in latest BIOS (01.04.01 in the other HP platform - 440 G7). Thus, could you please help to upgrade your BIOS to latest to see if the issue presents? If so and if your machine is listed on Ubuntu certification page[3] then I can help you to escalate this issue. BTW, this issue is only happen on "a machine did boot to Windows with HP application". Thus, it'll probably not happen in Ubuntu certification process. If any of you meet the issue on Ubuntu certified platforms then feel free to report a bug.
