Suspend not working on Dell Inspiron 15 5000

Post by JumpingJoe0 » 2022/01/06 05:15:04

I can suspend my laptop, but cannot get it to restart, which defeats the whole purpose.
For example, if type:

Code: Select all

$ systemctl suspend
The laptop will indeed go blank. However pushing the power button, or any function key does not wake it up. It has been this way since I got the laptop 2 years ago. Never changed as I upgraded the kernel version over that time. I suspect there is some BIOS setting that could help, or maybe a particular keyboard sequence.

My goal is to be able to shut the cover, causing it to suspend or hibernate, then recover when I open the cover. First I need to know how to recover. Probably hardware specific, I have a Dell Inspiron 15 5000. What do I do?

Here is a link to the results of running

Code: Select all

$ getinfo.sh

Here is a little more information:
If I momentarily push the power button when it is running the screen immediately goes blank, the fan turns off, the keyboard light goes off. I assume it has correctly gone into suspend mode.
If I then again momentarily push the power button, the fan turns back on, and the keyboard light goes back on, but the screen remains blank. I am guessing that it has resumed operation, but failed to activate the screen.
What do I do?

Here is a link to my /var/log/messages file for a time when I tried to halt and resume the system:

Here are times I tried to sleep and wake the system using the power key:

Code: Select all

[Joe@localhost Centos]$ grep Network messages-20220109 | grep sleep | grep requested
Jan  8 23:47:44 localhost NetworkManager[4961]: <info>  [1641703664.4619] manager: sleep: sleep requested (sleeping: no  enabled: yes)
Jan  8 23:47:59 localhost NetworkManager[4961]: <info>  [1641703679.5008] manager: sleep: wake requested (sleeping: yes  enabled: yes)
Jan  8 23:48:13 localhost NetworkManager[4961]: <info>  [1641703693.6480] manager: sleep: sleep requested (sleeping: no  enabled: yes)[\code]
