I own a Lenovo SL510 (4G RAM) and I just upgraded it with a Samsung 840 Evo 120G.

Previously I was using Ubuntu. Later on I switched to Linux Mint Nadia. At the very beginning (Ubuntu 10.10 I guess) I remember having problems getting my system into suspend to RAM. But this vanished with 11.04. I am using 14.04 now.

After the SSD upgrade the problem occurs again. I set my notebook to standby using either FN + F4, sudo pm-suspend or the menu. All three fail with the same symptom:

  • LCD goes black (even backlight)
  • Fan stays powered
  • Power-LED blinks ("blinking moon of death")

I cannot recover the Notebook from standby. I have to kill it by pressing 5s the Power button.

The weird thing is that it doesn't occur always. In about 20% of cases standby works as expected. Patterns observed:

  • immediately after power-up a standby never works
  • if after standby-ing the logon-screen appears, standby always works
  • but sometimes standby works also without a visible logon-screen
  • after standby worked first time during a session, it's not guaranteed but more likely to work again

So to all the Sherlock Holmes out there: I'm sure the problem can be fixed!

There are many forum entries for this very particular topic but none had a working solution. I already tried debugging and fixing this on various ways but I was not fortunate. What I want to do now is a focused search for the error.

I will start with posting log-messages and debugging steps in the comments.

It seems like this solution is working:

  1. install uswsusp using: sudo apt-get install uswsusp

  2. start standby using sudo s2ram -f -a 1

Solution found here (similar problem): https://unix.stackexchange.com/questions/94735/linuxmint15-suspend-to-ram-not-working

Disk encryption is also in use here, so perhaps this is the crucial thing.

I am interested in making this my default suspend application on all shortcuts (closing the lid, fn + f4 etc) - still searching on a solution for this one (the /etc/pm/config.d/anything-stuff doesn't work)

edit: even this solution won't work in any case :-( I am frustrated.
