Power button not working

@bensonamoke since it happened after a drop, it is possible that this is some mechanicl issue with the actual button. Since iFixit does not have a guide for that, use something like this one Check the flex and the button etc. If in doubt and you are not quite sure what you are loooking at, post some pictures of it with your Question. Use this guide for that Adding images to an existing question

While you work on your drive, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
