Re: [coreboot] Can boards wake up from S3/4/5 by specific keystroke

Hello Zheng, Since you are asking again, I looked into this problem, in order to understand the whole PM domain more... Here is my assessment, so I would advise you to try several options for such a problem. I would advise to you the following steps (which, unfortunately, have nothing to do with Coreboot for the initial test): [1] To install the latest BIOS for ThinkCentre M6600q (Lenovo), or to use the current, present in the platform; [2] To drive CMOS settings to PM (Power Management) and check if PM is properly enabled in BIOS (this is a MUST!); [3] Then, if both steps are done, to install Ubuntu or Fedora Linux distros (I personally prefer Fedora); [4] To install the following package in given distro: pm-utils! https://pm-utils.freedesktop.org/wiki/ http://pm-utils.freedesktop.org/releases/pm-utils-1.4.1.tar.gz [5] Then to configure, make and install this package (I did it on my VM F24 for this purpose, traces imported): [zoran@localhost Downloads]$ cp pm-utils-1.4.1.tar.gz /home/zoran/projects/pm-utils [zoran@localhost Downloads]$ cd /home/zoran/projects/pm-utils /home/zoran/projects/pm-utils [zoran@localhost pm-utils]$ ls -al total 212 drwxrwxr-x. 2 zoran zoran 4096 Sep 1 09:32 . drwxrwxr-x. 8 zoran zoran 4096 Sep 1 08:59 .. -rw-rw-r--. 1 zoran zoran 208687 Sep 1 09:32 pm-utils-1.4.1.tar.gz [zoran@localhost pm-utils]$ tar -xf pm-utils-1.4.1.tar.gz [zoran@localhost pm-utils]$ cd pm-utils-1.4.1/ [zoran@localhost pm-utils-1.4.1]$ ./configure [zoran@localhost pm-utils-1.4.1]$ make [zoran@localhost pm-utils-1.4.1]$ sudo make install [zoran@localhost pm-utils-1.4.1]$ which pm-suspend /usr/local/sbin/pm-suspend <<======================== S3 state [zoran@localhost pm-utils-1.4.1]$ which pm-hibernate /usr/local/sbin/pm-hibernate <<======================= S4 state And then try to exercise given commands, and to revive platform using keyboard/mouse wake up. We'll go from there, and we'll try to debug ThinkCentre M6600q (Lenovo) if it does not work at this stage. Maybe somebody can advise you with Coreboot solution... But essentially, above proposed method by me should work!

I am wondering how it is implemented? Is it done in chipset, BIOS, or a special keyboard? Or when the BIOS wakeup, it reads the keystroke to see if it matches the pre-defined key. Does it sounds reasonable? Zheng
