Answer to: Keyboard backlight only glows in center 10/07/2010
Rob. The question is not dumb. If your keys are a little sticky you can remove the affected keys gently and wash them and the plastic assembly underneath them. This is not hard to do but you have to be careful not to brake them as you snap them out and in. If you want to fix the backlight in the centre of the keyboard issue you will need to open the MBP. Opening it is quite easy, all the instructions are on this website. Once you have removed the top cover from the MBP aluminium chassis it is easy to remove the keyboard. Then you have 2 options 1) dip the whole keyboard in warm water with a few drops of dishwashing detergent. shaking it gently for a few minutes. Now you have to rinse it in another container with warm running water. To dry it you should use COLD air from a compressor, directing the air from the external edges of the board so that all the layers inside are dried. Alternatively you can dip the keybpoard in a solution made up of 50% water and 50% ethanol or methylated spirit, shake it and now ins...
Answer to: Keyboard backlight only glows in center 09/13/2010
Update on "backlight only glows in centre" My A1260 had the same problem. Someone dropped some sugary substance on the keyboard before I got it. I thought the lights were behind the keys and that the circuitry was damaged by the liquid. I pulled the keyboard of and fully apart (tricky job and very time consuming) As it turns out (as Thomas pointed out) the backlight system is spectacular! there are 3 layers on the bottom of the keyboard just for the backlight system. From bottom up here is a description. 1 ) White plastic layer. This contains a small circuit and 4 LED. These are sealed so they cannot be damaged by a simple spill 2 ) Transparent Perspex layer: The 4 Leds on the white layer fit into 4 slots on this perspex sheet. This sheet has several white dots that serve the purpose of reflecting the light that comes from the diodes at 90 degrees up to the key. the density of the white dots vary to ensure equal illumination of all the keys. Brillianyt idea! 3) a thin plastic transparent layer with a black gr...

Thomas, your answer is nothing short of brilliant! I dismantled the keyboard completely thinking that the lights were under the keys, but they are not. The A1260 keyboard has 4 LEDs attached to a white sheet which illuminates sideways the transparent sheet with the white dots.I have not put it all back together again... wish me luck John
