I've had a similar problem with my T410, running sid.
I was losing the first few keystrokes when I begin typing on a USB
keyboard. I didn't connect it with sleeping.
At the moment (typing on USB keyboard I plugged in to test)
I don't see the problem.
Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.3 (Debian 4.8.3-13) ) #1 SMP Debian 3.16.7-2 (2014-11-06)
cheers,
