z50-70 keyboard power management issue

2015-07-03, 20:33 PM

Hi

 

I seem to have an odd issue with power management. I have installed windows from scrach (8.1 pro) and seem to lost the option to wake the laptop from sleep using keybaord. The power management option is not there in the device details. It has the Standard PS/2 Keybaord installed but the power management option is simply not there. This worked fine on the factory install so i know that it can do this. I have not changed any bios settings. I can wake it up from sleep with a mouse but both keyboard (built in one) and touchpad dont do it anymore.I tried everything i can think of bbut no success. And yes, the lenovo power manager is installed and working fine.

 

Many thanks for all the help.
