F1/F2 used to work for brightness but stopped working a long time ago. F3/F4 do nothing.
Even if you depress the fn key (in the lower left-hand corner) at the same time?
We'll probably get in trouble for getting off topic here anyway.

this thread, and then say the same thing with a straight face. Dare ya!
Ok, Ok, you made me laugh. From battery questions, to Starbucks flat white drinks to Paypal. Wow!
As to the F keys, you're right, when I press the fn key, they work and I can use F2 for my brightness now. Don't know how I missed that. Thanks!!
Should we talk about coffee now just to round out this thread? Just kidding. I'm done. Have a good one.
