so, during a long trip, i open up the PC like normal and 2 keys, have come loose and they got removed entirely, and i cant seem to get them back on keys, are numbers 3 and 4
Keyboard keys can be a bit fiddley, but it’s usually just as easy as lining them up and pressing down until it clicks, if they aren’t staying on or are loose you’ll also have to check for damage. The part of the key that connects to the hinge, and the hinge itself have tiny plastic pieces that can be damaged easily. If there is damage you can buy replacements online, this particular website also has little tutorials, although generic. Let me know if this helps.
