I recently built a newer system to replace an older Pentium 4 based one. On the old system (openSUSE 12.3/XFCE) I was able to wakeup via keyboard press (the keyboard was/is a Logitech K800 USB wireless). The newer system (openSUSE 13.1/KDE) is built on Asus H81M-PLUS motherboard with UEFI. I have verified the two applicable jumper settings and believe the UEFI settings to be correct (this is my first experience with UEFI). I’ve read quite a few threads related to this issue but have not found the answer yet. I have also noticed that on regular start from cold boot there seems to be a delay at login screen before keyboard output is accepted. This seems to affect the first character typed which generates no output, then the output to password dialog is as expected. Not sure if that delay is helpful in diagnosing the wakeup issue or not. Other than these issues I have been very pleased with 13.1, and especially KDE performance since I had moved away from it several years ago due to the older hardware I was running.
