Login as root via SSH. Captured the register dump with: intel_reg_dumper > regs.1 Run: pm-suspend Wait for suspend to happen. Press the power button. The computer comes back to life (net connections are resumed), but the screen remains black (no backlight even). At this point I captured dmesg in dmesg-1.log.
Created attachment 37077 [details] Register dump before suspend
Created attachment 37078 [details] Register dump after suspend
Created attachment 37079 [details] Dmesg after resume (contains all messages since boot)
Possible dupe of #28739. Please check the patch in that bug. *** This bug has been marked as a duplicate of bug 28739 ***
I confirm that this patch: make sure panel power is enabled on eDP (1.17 KB, patch) 2010-07-14 12:21 PDT, Jesse Barnes fixes the problem on this laptop. Thanks for the quick answer!
