It is indeed not advisable to leave a kid alone with the computer. Just a while ago, I had hard times replacing my keys removed from my computer (laptop) keyboard. The keys are removable for easy cleaning, but not when the rest of the parts are completely off and it was hard to figure out how they placed them so to work originally as they were.
It took long and I was scared and worried that the small parts attached will break and it will end up a waste. Thank you eyes for a very attentive look. Now they all work fine.
