APM vs. ACPI

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 he 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 or lacking hardware implementation)
• part = partially working (unsolvable trouble on resume or something like that)
