Same issue here on hibernation with Feisty on a Vaio VGN-S2XP, but I've found a workaround that seems to work. First I've changed HIBERNATE_MODE=shutdown (/etc/default/acpi-support) to HIBERNATE_MODE=platform (this value reduced energy drain while the system is hibernated). To completely solve the problem I had to deactivate WiFi and Bluetooth before hibernating using the hardware switch that controls both.
I've noticed that Usb is still powered when the system is hibernated, and the internal Bluetooth is attached to the Usb bus. Moreover during hibernation process I have to remove modules usbhid uhci_hcd ehci_hcd (using "MODULES=" in /etc/default/acpi-support) in order to avoid some error messages about Usb. I've tried video=radeonfb:force_sleep in /boot/grub/menu.lst and radeonfb force_sleep=1 in /etc/modules with no success. -- Toshiba laptop battery is drained while shut down https://bugs.launchpad.net/bugs/110784 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
