So, I'm hoping that posting as much as I know will get me some responses to help me along on this. I recently acquired a new laptop, an HP 17" with Core I7; it's the 3085dx which is the off-the-shelf Best Buy version (yes, I know, but I needed a machine quickly and that was best option).
6 Gigs of DDR3, discreet Nvidia GPU (1 gig dedicated), 500 gig SATA disk, etc.
It seems HP has been less than forthcoming in providing proper Linux support (something I didn't expect as for me, stuff has always just worked). It ships w/ Windows 7 and HP's official response seems to be on the pavilion and envys that "we certify for Windows Vista/7 and provide no support past that". After getting past HP shipping the machine with 4 primary partitions defined for Windows, I got Ubuntu running with mostly no issues. I had noticed when I reboot after being in ubuntu that I get a "Your machine has been running hot, please check fans arent blocked" warnings, which I've chalked up to simply some software probe not reporting back to the BIOS.
The one other issue I've had is a failure to wake up from suspend. It works fine in Windows of course, but under Ubuntu when I wake the machine up I get a blank screen with a blinking white cursor. I've tried adjusting the configs to turn reposting video on and off, to no luck. As I was digging around I found some stuff about ACPI and found out my machine was in fact overheating, as the system wasn't properly managing fans. I also found in dmesg "Unable to parse ACPI, possibly buggy BIOS" messages. I added a suggested option of acpi_osi=!Linux to kernel parameters - my temp sensors are SIGNIFICANTLY lower now and I notice the fans running, although I still get the "BIOS Overheat" warning at reboot. I also get about 8 pages more of ACPI output and ACPI seems to boot more correctly now however.
I'm now of course concerned about everything not working. I'm more concerned of the system overheating due to not talking to the BIOS correctly, not being able to suspend, etc. While Windows 7 is not nearly as bad as past attempts, it still isn't suitable for my needs.
I'm looking for any and all help to nail down full support for Fan control and temperature sensors on this machine, making suspend work, etc etc. I've attached sanitized dmesg, dmidecode and lshw output. I'm happy to provide other output as needed but looking for a solid direction to head in to resolve any outstanding issues on this. Windows is not an option, and I've come to the realization of shortcomings too late to return the box at this point.
