No "Battery Optimized Performance"

Description

Using eCS 2.0rc1, w4 kernal, ACPI 3.01, APM 1.16, Gateway 7405GX laptop (Athlon 64, VIA K8T800 chipset). The 'Power' object is set up for 'Maximum Performance' when plugged in and 'Battery Optimized Performance' when not plugged. Unplugging the laptop causes the screen to dim and the Power object (and battery widget) shows it is on battery power. On the Power object however, under 'Power and Performance Optimization' it remains 'Maximum Power'. Since the screen does dim, it is not clear if this is true.

Also, in the Power object properties, on the power tab, the setting 'Enable state changes due to inactivity' will not 'stick' - if I check it, on next boot it is no longer set. Not sure if this is supposed to be supported.

It appears this computer supports throttling (state.log from setgetstate), but remains disabled (pluggedin.log, unplugged.log from setgetthrtl).

But... setgetstate (unplugstate.log) when unplugged shows that it is using C2, so now I'm confused...

OK... I'm slow but now I get it... setgetstate is strictly power state (unplugged behavior), setgetthrtl is user state (idle, manual power adjust). It seems unusual that this laptop supports these even though it is an AMD processor.

  • Resolution set to wontfix
  • Status changed from new to closed

This options in object "Power" for IBM apm system (apm.sys + apmdaemn.exe). I don't see set this parameters to apm driver. Also, this feature is udocumented. So I can't implement this to acpi apm. You can use CRC for this features. Also you can use SetGetState? and SetGetThrtl? to manually setting. But. For AMD CPU's this don't working, because developers of MB don't insert handling power to acpi table.
