Description Gene Snider 2023-08-14 18:51:48 UTC

My Dell Inspiron 16 3525 laptop refuses to wake from suspend. After many kernel upgrades (5.17 - 6.5-rc6) and  BIOS (1.06? - 1.12) updates, the problem still persists. This problem is well known on Dell's website, with all versions of linux. What I've found so far is that after forcing a power off and rebooting, the command:

journalctl -b -1 | tail

Oct 03 14:44:53 Mobile-PC kernel: PM: suspend entry (s2idle)

This shows that the system successfully entered s2idle sleep, but was unable to wake up. I have tried enabling wakeup for all possible inputs in powertop, but nothing changed.

This command shows that the kernel thinks this laptop supports s2idle sleep:

> cat /sys/power/mem_sleep 
[s2idle]

However, this Windows 11 command says otherwise:

powercfg /A

It tells me that my hardware only supports Standby (S0 Low Power Idle), and specifically states that s2idle is not supported. So, after every bios update I try suspending to RAM to see if the problem has been fixed.

Here's my hardware:

As you can see above, I'm testing the latest kernel from branch master, but it produces the same behavior as all the previous kernels.

Any ideas or information requests?

I forgot to include this, the link to my openSUSE bug:

The code says:
        /*
         * Suspend-to-idle should be supported even without any suspend_ops,
         * initialize mem_sleep_states[] accordingly here.
         */
        mem_sleep_states[PM_SUSPEND_TO_IDLE] = mem_sleep_labels[PM_SUSPEND_TO_IDLE];


So s2idle is taken as always "supported". I am not sure if it really is on your laptop. CCing suspend people.
