There has been a problem encountered where the display stays black on resuming from suspend.

The symptom might have you think first that your system hang up, but you will realize that your ThinkPad works and you can even reset it via CtrlAltDel.

Affected Operating Systems

  • Linux (it's a kernel issue)


The Solution is to provide the acpi_sleep=s3_bios kernel parameter in your kernel parameter line.

For grub this can look like this:

title           Linux, kernel 2.6.11-1-686
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.11-1-686 root=/dev/hda1 ro acpi_sleep=s3_bios
initrd          /boot/initrd.img-2.6.11-1-686
