So, updating my BIOS, sadly, did not fix the problem. The result was exactly the same. I suspend the laptop, then resume it. The machine resumes from suspend in every respect except that it doesn't turn the backlight on the screen back on.
With the new BIOS, the output of `sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date` is: 8IET41WW(1.14) 02/26/2013 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1034002 Title: Lenovo E525 screen black on resume To manage notifications about this bug go to: https://bugs.launchpad.net/dri/+bug/1034002/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
