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 Models
Affected Operating Systems
- Linux (it's a kernel issue)
Solution
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 savedefault boot
| FOOTNOTES [Δ] |
- If you have this problem with R50e and the above solution doesn't work, try switching to console first. An example sleep script can be found here.
