I bricked my Samsung 840 Pro after just one Suspend to RAM. I had luck
and entering BIOS was still possible. I since then disabled the "Intel
Rapid Start Option" and I am in deed using UEFI only - with the legacy
option completely disabled on Ubuntu 13.10 with mainline kernel.
I am running that T440s since then without any issues. I believe the
"rapid start" option made the difference for me.
Now I am a bit confused, cause I should have bricked it by now at
least multiple times me UEFI running. I am using Kernel 3.13 and have
run the 3.13-rcs before.
