[Bug 377538] New: Regress in power management
https://bugzilla.novell.com/show_bug.cgi?id=377538 Summary: Regress in power management Product: openSUSE 11.0 Version: Factory Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: lavrinenko_alex@mail.ru QAContact: qa@suse.de Found By: --- Hello, recently I found that latest kernels from factory (2.6.24.1 and above, currenlty 2.6.25-rc7-git2-11) drain my laptop's battery much quicker compared to 2.6.24-rcXX. Right now my laptop is able to run 4+ hours under winXP and less than 2 hrs under current kernel. Hardware is HP nc6400/BT and WiFi always on, LCD brightness is autodriven by light sensor. Tests made under the same conditions: one copy of browser (MRTG, 5min interval refresh), Word/OOWriter, one PDF opened, external USB mouse connected. In reality in linux laptop dies after 1 and 1/2 hours, under winXP it lasts up to 4 hrs. I do not have dual boot, linux is on the same 80GB 2.5" sata hdd as the one with factory winXP that was preinstalled in laptop. For tests I swapped back winXP hdd. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

... but somewhen before a lot usb/kbd interrupts were triggered. I used to suspend laptop instead of powering it down. Its' uptime is at about 6 days at the moment of logging.
