Linux on the HP 2530p
Two weeks ago or so I got a lovely new laptop, the HP Elitebook 2530p, but quickly found that ACPI on it would make it hang at boot. I installed with acpi=off, and used it as a desktop-style testing machine while we tried to figure out what was going wrong with it. It was kind of rough, as someone who's never debugged ACPI before -- the googling gives you documentation that advertises itself as stale (so why does it exist?), and the real documentation isn't where it should be. The ACPI guys I know seemed stumped -- various debug output all came up clean, yet enabling ACPI caused boot-time hangs in the ACPI battery, ACPI thermal, and HDA drivers.

It turned out after I nuked a bunch of BIOS options, that the option to enable the fan while AC is on is what was causing it. Disable it for linux on 2530p happiness.

Also, suspend/resume works out of the box, as long as your box includes loading the Intel DRM.

"fan while AC is on" is good!

Having another HP laptop at work, the only thing that makes it bearable is the "fan while AC is on" option, since otherwise it will let the computer overheat and then perform some violent and loud fan emergency action (when the fan is always on OTOH, it's whisper-quiet).

You may regret this workaround fast.

Never had the time to try Linux on that computer though.

thank you VERY VERY much for your hint. I have been already spending with this bug 2 days long. I've upgraded bios to F07 (from Jan/2009), I tried everything (except your hint) and I was unable to boot Ubuntu live CD (8.04, 8.10, 9.04aplpha4). only alternate CD (8.10) with acpi=off worked to install (text mode) and then to put acpi=off into grub, but after update to 2.6.27-11 keyboard + touchpad stopped to work, I had to use external one. THE LAPTOP IS SUSE ENTERPRISE DESKTOP 10 CERTIFIED. so I tried OpenSuse 11.1 and the installation works out of the box and the system too ... interresting. I tried latest Slax from USB too, with the same bad result as ubuntu (hang on CPU thermal detection - without battery inside / or on battery status with battery inside). But after applying your hint it runs out of the box. Thank you very much again ! afk_cz.
