Keyboard not lighting up

Hello,

I’ve noticed over the last few day that the keyboard on my MacBook Air Early 2015 isn’t lit up at all despite it saying it is on full when I press F6. This has come on suddenly.

I’m assuming it might be a connection issue somewhere, especially if it is allowing me to alter the brightness settings for the keyboard but I could be wrong. When I press F5 and F6 it isn’t doing anything but presents as if it is changing the brightness.

Any help and advice is appreciated! :)

Cheers,

James

Could be the cable has become dislodged. The cable for the backlight is beside the keyboard connector on these, between that and the battery.

Before opening it up, and you’ve probably already done this, check that the ‘adjust keyboard in low light’ box in the keyboard settings in preferences isn’t ticked.

Thank you for this. How do I access the keyboard connector? I've tried to Google it but couldn't find an answer. I've taken the back case off.

@danj Cheers Dan. I just had a look and it is plugged in. I took it out and put it back in but unfortunately the lights still won't come on.

@jamcam - did you try resetting the SMC yet?

You'll need to check the voltage at the pins. If you get power then the keyboard backlight plate is damaged if you don't then the backlight power logic on the logic board is damaged and will need repairs.
