[EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEEDINFO |REJECTED Resolution| |INVALID ------- Additional Comments From [EMAIL PROTECTED] 2007-05-20 14:27 ------- Thanks for testing. The results confirm that the ACPI BIOS will change the trip-points to implement hysteresis when it crosses the ACPI trip points. Yes, this will wipe out any modifications that the user has made to the OS copy of the trip points. Further, as the user no longer sees the ACPI trip-points, the user may not know when this is going to happen, and would thus have to continuously over-ride the OS trip points on every temperature change or trip-point event to make the over-ride effective. Finally, if the user does not enabling polling, the modified OS trip points have no effect at all except to deceive the user into thinking that they've implemented a change in policy - since the BIOS continues to work with the real ACPI trip points. For these reasons, the ability for the user to over-ride the OS copy of the read-only ACPI trip-points was a bug, and removing that ability was a bug-fix. You have confirmed that you can over-ride the state of the fan until the next ACPI trip point is reached -- and that is what you should do if you disagree with the policy implemented by the system vendor. If too loud, turn off/down the fan. If too warm, turn on/up the fan. Also, if the vendor (had) implemented _SCP (cooling_mode) that would give you a choice in cooling policies. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
