General Information about Power Management features
This page should give you all the information you need to make use of your ThinkPads Power Management features under Linux and hence effectively enhance your battery life.
APM vs. ACPI
All ThinkPads support APM and a lot support ACPI as well, but at different qualities of implementation. So the choice which to use depends very much on the model as well as on the state of ACPI support in the kernel.
ToDo...
How to enable certain features
The following links will take you to separate pages dealing with the various topics.
- How to make APM work (Screen Blanking, Suspend to RAM, Suspend to Disk)
- How to make ACPI work (Screen Blanking, Suspend to RAM, Suspend to Disk)
- How to make use of Dynamic Frequency Scaling (Speedstep, Throttling, etc.)
- How to make use of Harddisk Power Management features (Laptop-mode, Spindown, etc.)
- How to make use of Graphics Chips Power Management features (save even more battery power)
