Re: Portege Z830: Keys for eco, presentation and on/off don't work
in response to: whuber
I don’t know if you use original OS that you got with your notebook or maybe own OS installation but fact is that these buttons are controlled by small Toshiba buttons control tool. This tol is part of Toshiba Value Added package so just follow advice posted by MisterX and reinstall Toshiba VAP.
I hope this will help.
Be so nice and post some feedback.
