The following tables headings shell designate the following meanings... APM Blank = ability to turn off the LCD while using APM Sleep = ability to do a suspend-to-ram using APM Hibernate = ability to perform a suspend-to-disk via the BIOS Battery = ability to get statistics on remaining battery life from the APM subsystem ACPI Blank = ability to turn off the LCD while using ACPI Sleep = ability to do a suspend-to-ram using ACPI Hibernate = ability to perform a suspend-to-disk using ACPI Battery = ability to get statistics on remaining battery life from the ACPI subsystem The fields should be filled with one of the following:  ? = unknown / untested yes = working (with or without extra configuration effort) no = not working (because kernel support isn't there yet) part = partially working (unsolvable trouble on resume or something like that) N/A = not supported by the hardware ACPI-Hibernate can additionally have one of these: sus - hibernation works using the old in-kernel (2.6) swsusp sus2 - hibernation works using Software Suspend 2

T20 Hibernation:

• tested with SuSE 9.2
• APM needs a special file on a windows partition

R51e Sleep:

• tested with Kubuntu 6.06
• R51e needs the BIOS/firmware update from february 2007 to successfully resume. Resume completely hangs (no screen, no keys) with older software.
