 Posted: Mon Nov 21, 2005 5:06 pm Post subject: ACPID scripts for thinkpad T42 |
 |
|
Here's my current ACIPD scripts, its not complete quite yet, but i'm looking for some critiques on how to improve it and/or hopfully make it more effective, the case statement for detecting the correct events, and a few functions such as susp2ram and susp2disk haven't been written yet because to be frank, i have no idea about susp2ram/disk and at the moment i'm doing research on this.

Any suggestion for improvement and/or things that i may want to add to the scripts. |
