I just tried suspend and had a very scary thing happen. I noticed an error message in dmesg,
ACPI-0412: *** Error: Handler for [EmbeddedControl] returned AE_TIME So I did some Internet research and found this to fix. Added, noapictimer ec_burst=1 to the kernel line in /boot/grub/menu.lst. Also did a, update-grub. Reboot and the ACPI-0412 message was gone. Great I thought. Then I wondered if suspend would now work so I tested. Laptop shutdown normally and I had the flashing light telling me the laptop had suspended. Then I press the power button laptop powered up and promptly froze like before. Then I forced a reset by holding down the power button. Then when I tried to turn the laptop back on the power lights would only flash on for 1 second then shutdown. I thought I bricked my laptop. However pulling the battery and waiting a few minutes brought her back to life. I am also getting a, ACPI: Looking for DSDT ... not found! message. I hope this can help to isolate the problem. -- Suspend and Hibernate Fail with i830MG (on Mitac 8355/ThinkPad) https://launchpad.net/bugs/46680 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
