Comment # 31 on bug 906026 from Jean Delvare

If boot parameter "atkbd.reset" doesn't help then please remove it.

Your laptop is running BIOS version 1.02. According to the vendor's web site,
updates are available. In particular, BIOS version 1.04 has the following
changelog entry which seems quite relevant:

04. Fix TouchPad PTP/PS2 no function issue for hybrid shutdown.

While "Hybrid Shutdown" is a Windows thing, I'd say it is still worth a shot.

I can't see any problem in the /sys snapshots you attached, everything looks
the same before and after STR.
