Hello everyone! I bought an Acer Swift 5 SF515-55T in April, with a backlit keyboard. A few nights ago, Windows II must have updated itself, and I turned the laptop on in the morning to find the keyboard was no longer backlit (though otherwise it worked fine, and still does). After trying various things myself I phoned the Acer helpline and was told to reset the entire laptop. I have now done that *twice* in case I did it wrong the first time, I've reinstalled Windows from the cloud, but my keyboard still does not light up when I type. It does temporarily light up when I turn the laptop on, so it's not that the lighting has stopped working altogether, it just doesn't respond to touch any more.
What do I do now? Please help!
