Things that started happening at the same time that I began getting this bug: Brightness meter APP stopped working, it disappears when i click the slider bar; wireless says pending connection and requires a reboot; wireless cuts out often soon after changing to powersaver with CPU Frequency Scaling Monitor APP; power usage dropped but crashes randomly after plug in/out. Ubuntu crash randomly after a startup off battery.
Things that I tried but didn't work: I Downgraded "pm-utils" to 1.3 and locked it. Restarted and it froze again quickly. Things that seemed to work so far: Completely removed "pm-util" along with "acpi-support"?(memory laps) and "can't remember" ;then for fun and good measure i searched for "power save" and I installed "laptop-mode-tools"(Tools for powersavings based on battery/ac status) "rovclock" (frequency control for Radeon Cards) "uswusp" (tools to use userspace software suspend provided by linux) I restarted and left it sit running on battery and it didn't seem to crash but laptop mode gave me a little trouble sending me to a message screen so i removed it after ;Currently after realizing what to tools are for I removed "laptop-mode-tools" "rovclock" "uswusp" rebooted and have been running on battery on and off for 30 minutes after booting off battery with decent power usage and fan off time. Then I reinstalled "pm-utuil" without restarting and without reinstalling "ACP-support" and it continues to run so far even when i mess with the CPU frequency unplugged. I have a HP TouchSmart Tx2 1024ca Ubuntu 10.10 (Not 11.04 because I'm afraid of grub2 updates for compatibility with startup manager and my default boot) 64 bit AMD x2 64, ATI Radion 3200 with catalyst control center installed and powerplay on. I'm not shure if this is to much info but this is my experience. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776999 Title: [Lenovo W520] laptop freezes on ACPI-related actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
