also, the electricity that goes trough your keyboard is extremely tiny, and sensors are VERRY sensible, so your air battery can lasts longer. Problem is: separation is the same as an average good quality book paper sheet, or maybe the same as the aluminum sheet that makes a soda or beer can. When you press a key, the top and bottom plastic are pressed against one another inside the hole of the middle layer, and the electronic signal going from the top to the bottom layer tells your computer that the key is pressed. Keyboards are 2 layers of plastic film with tiny electric contact, separated by a third layer of plastic film with holes on the spot of every single key.
#Apple mac pro keyboard not working Bluetooth#
An external keyboard (either bluetooth or usb) doesn't behave differently.It feels like there's some function/alt/ctrl/shift key that might be constantly pressed, but I can't tell which one, or make it behave differently by pressing those. For example, pressing the N key once doesn't show a keystroke, but pressing it twice does. Some key-presses seem to be registered but obviously not the correct ones.
#Apple mac pro keyboard not working password#
I can't enter my password at the boot screen.The caps lock, arrow, enter, esc keys all seem to work.The laptop boots into the drive selection screen every time (alt key constantly pressed?).The computer seems to work but the keyboard doesn't. I spilled coffee over my mac's air keyboard yesterday.
