sometimes it works, and sometimes it doesn't...more often than not, it doesn't. I have my macbook air plugged into an external monitor and using the bt mouse and kb and plugged into the wall outlet. After using the computer, the display will go to sleep ( i set the machine not to sleep when plugged in so i can share files to other computers).. so, when i go click the mouse, sometimes the display wakes up and comes on...but most of the time, it just stays in standby mode. Only way i can make it come on when this happens is either opening the lid of the macbook air, or turning off the monitor then turning it on and clicking the mouse button again. Its like the macbook forgot it was plugged into a monitor... strange that it doesn't happen consistently.. anyone else have this issue, anyone have any ideas on how to fix it? thanks for the help!
