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.
