We're all just really smart monkeys here, and communication is complicated. "He's always trying to fix things when I just want to talk" is this same interaction just in a home context. Same communication error. There's a gap, you're saying "Do you know, at this moment, how to do this" to which the answer is clearly no. However, men are hearing "Can you solve this problem for me". Giving you back the keyboard means admitting that I failed to fix it.
EDIT: In my head, I feel like you've given up on the idea that I can help you, and you're probably going to go find someone smarter and more competent than me. In this context, a guy who doesn't want to give the keyboard back is afraid of admitting failure.
