Re: ThinkPad T30, ACPI: backlight stays on during suspend

Quoting eddyp:

USB is known to raise some issues with ACPI S3. A possible workaround is
removing the trouble-making USB module before entering S3:

    modprobe -r uhci_hcd
    echo "mem" > /sys/power/state

After resume, reload the USB stuff:

    modprobe uhci_hcd

Works fine for me on a ThinkPad R32 (which won't suspend with "uhci_hci"
loaded either).
