[ltp] X1 carbon 2015 can't resume from suspend
Sun, 29 Nov 2015 18:39:29 +0100
I really tried and searched before writing this. I have found many similar
topics but nothing lead me the right way.
I have a Thinkpad X1 carbon, brand new. I'm running the latest vanilla Kernel on
it. The notebook runs nicely, I have the GPS modem, wifi and everything working.
But when it comes to suspending the system, I have no luck.
Setting the system to suspend using "echo mem > /proc/power/state" seems to
suspend the system. At least it stops talking on the ethernet, switches off the
screen, and the power button light is doing a slow and soft blinking.
That's all. I am completely unable to get the computer awake again. Power
button, wild fn+something combinations, closing and opening the lid, connecting
and disconnecting power: Nothing helps. I have to turn off the computer by
holding the power button.
Downgrading to kernel 4.2.0 did not change anything BTW.
I completely threw out all graphics drivers from the kernel, system running in
text only mode.
I further got a BIOS update from Lenovo. The version is now 1.11
The computer's model name is 20BS.
It's really really annoying :-(
Does anyone has tips for me? Is my laptop broken? Did I forget something
