Ok, so, if anyone has my case, then they may have already tried the one where you hold down the “s'“ key. I have been doing that since forever, but now it stopped working. Instead, I do a few other things. Sometimes not all of them work, so I may go down the list again or do my last resort that sometimes works.
# Blow your keyboard. There may be dust or other matter underneath, so blowing under the keys that don’t work will push those away.
# Turn Laptop upside down and gently shake. Any crap underneath your keyboard will fall from underneath them.
# Option 1 and 2. Turn keyboard upside down, gently shake side to side, and blow.
# Last resort. Violently shake your keyboard. Mines stops working after moving around a lot. I use my computer on the go, and when I go from one place to another, sometimes it stops working and sometimes it will start working again, because of whatever movements I do to my computer while I walk. Shaking my keyboard usually works best.
