Strange keyboard and trackpad behaviour after crash

[qoy]

Hi,

today my Mavericks crashed while apparently sleeping. At least I put it to sleep before coming home, finding it an unresponsive state; displays were blank and I couldn't SSH in. So I hard-resetted.

Since then my trackpad isn't working properly anymore: the only thing I can do is move the cursor and click; no gestures, tap to click or secondary clicks!
Keyboard is working for the most part but also has some sporadic hiccups: pressing keys (mostly Opt-<letter> combinations) trigger volume ups/downs suddenly my displays get mirrored. Somethings obviously wrong but I cant't figure it out.

Already changed batteries, severals restarts and file system checks. No luck!

Any ideas?

Thanks in advance!

Rebuild it from the recovery partition and restore from backup.

Don't have either!

Recovery partition is accessed by pressing CMD+R while booting.

As for backup, well you could try and external keyboard / mouse and try to backup to an external drive.

Ehm, not sure what you mean; isn't it a bit too late to make backups!?

Anyway I already reset my system...

Thanks anyway!
