Please describe the problem you’ve encountered in detail:

  • Description: Hi everyone, me again! I am having issues with my laptop going into sleep mode, when I close my laptop screen, or let my laptop go into sleep mode, I can’t wake the screen up. The keyboard works (lights up), but not the screen. I have seen a few posts saying to look into edit the hwtuner to S2Idle, however when I go through the steps, when I need to the point where I select to select 0 to change from Deep(1) to S2Idle(0) - I get a flash text appear which then dissapears (so I can’t read it fully) but it says “Permission denied”

I am in Developer Mode, and I have also gone through the steps to disable root file system.

I know I can just turn sleep mode off, which I tried but then my laptop just died overnight, and I know I will forget to turn it off regularly, and it will be drained when I need it - so ideally please help me fix this :frowning:

sudo -i

mount -o remount rw

I just tried this under shell, but I got the following error message:

rw: mount point does not exist.
dmesg(1) may have more information after failed mount system call.

Any ideas? I am pretty lost. Thank youu

I just tried hardware tuner and the guide worked smoothly without remount. Just use sudo -i not sudo su.

Hacker, you are a KILLER! :raised_hands: Second time you have come to my rescue now!

It worked. I had followed your instructions wrong the first time. I followed the instructions the second time just as it described here: https://fydeos.io/help/knowledge-base/developer-options/hardware-configuration/power-management-settings/ but then in step 3, I used sudo -i instead of sudo su, or skipping the step as I was doing before. Looks like now it is going to sleep okay. Will see if my laptop is dead in the morning (like I will be Zzz) but looking good so far.
