Hi! Sadly, I have to say that I'm totally oblivious to power-related 
stuff both in software and hardware, so I have no idea what you are 
asking or proposing.. :)

I don't know if you have access to the files I've included in the bug 
report, so here are the links to them:
https://launchpadlibrarian.net/105830773/lspci.txt
https://launchpadlibrarian.net/95994294/AcpiTables.txt
https://launchpadlibrarian.net/95994318/BootDmesg.txt
https://launchpadlibrarian.net/95994354/UdevDb.txt

Regarding the syslog during boot, is that the same as the BootDmesg 
I've attached? Or should I search in another log file?
I'm not sure about the model, but I was hoping you could deduct 
something from the UdevDb or the lspci output above.

BR,
Peter
