Now the microphone key (F4) is stuck on (lit up) When I hold down the FCN key and hit ESC, then the Windows start up panel appears (like hitting the windows key) Is this a keyboard problem? Or, is there a simpler fix? Thanks! -FRANK
UPDATE: I installed a brand new keyboard. (Boy, do I hate working with T450 keyboards!). The result, unfortunately, was the same, i.e. the FCN, SPEAKER and MIC keys are still stuck on (lit up). So would this mean replacing the motherboard? Or, maybe just using this laptop for spare parts?
