GNOME Bugzilla – Bug 313070
Power source doesn't update when changed on suspend
Last modified: 2005-08-10 13:15:43 UTC
Please describe the problem: Changing from battery to AC when the OS is running isn't a problem, but if I suspend, pull the AC power, and resume, the system still thinks I'm running on AC. Plugging in AC and pulling it again corrects the status back to battery. If I suspend on battery and resume, it also has the correct status. Steps to reproduce: 1. Boot on AC power. 2. Suspend. 3. Pull AC power. 4. Resume. Actual results: The battery indicator thinks it's still on AC power. Naturally, "time to charge completion" just continues to increase. Expected results: The system should detect that it's on battery power when it resumes. Does this happen every time? Yes. Other information: Since I'm not familiar with Gnome, I'm not sure if this bug runs much deeper into the power source detection. I assume it does (even though I hope it doesn't), but I'm just submitting the obvious cosmetic effect.
Hi. This is a longtime known problem with laptops that have buggy ACPI implementations. The battery status applet in GNOME 2.12 contains a work-around in the ACPI code. In addition, the new applet uses the HAL (hardware abstraction layer) backend by default, which also has a workaround for buggy ACPI implementations. This should work for you when you upgrade to 2.12.0. *** This bug has been marked as a duplicate of 163013 ***
