LinuxCertified LC2210D Laptop Review

Provataki writes "OSNews posted a review of the LinuxCertified LC2210D laptop, running the latest Ubuntu. The laptop delivers pretty well and it has modern characteristics for a fair price but it's not without its small configuration issues. It is also another proof that Linux's ACPI sleep support does not work on most laptops out there, even the ones picked for best compatibility with Linux."

ACPI sleep

[mjg59]

ACPI sleep works on most modern laptops. http://www.ubuntulinux.org/wiki/HoaryPMResults has rather more "Yes" entries than "No" ones, and a large number of the failures are now well understood. Toshiba, IBM and (surprisingly) Sony seem to be good for ACPI support. For HP, it depends on the range - a lot of their hardware is very different. Older Dells seem good, and some of their modern stuff works without problems.

Additionally, the vast majority of sleep problems aren't in the kernel, they're in the bios (specifically, the DSDT as compiled by Microsoft tools). Go to acpi.sf.net for more information on broken DSDTs for more information on what this DSDT brokenness means to hardware compatibility, both device (e.g. sound cards) and suspend-resume and how to fix it (and maybe you're lucky and someone's already fixed your DSDT!)

Without fixing the DSDT, your best bet for suspend-resume on Linux is to use software suspend 2, as it seems to sidestep the BIOS/DSDT brokenness pretty well.
