Hi, My Macbook turns off after app. 10 secinds during startup. I did a lot of google on this, and can see different suggestions but no clear answer. If I hold a key on the keyboard, it sometimes will start, so I was able to do a backup. After new installation of MacOS it has the same error, so it must be a hardware error. I can see that a lot of suggestions point on the keyboard, and I could try to replace that, but I cant see a guide for this here. Anyone with the same experience og a suggestion on what to do? Thanks, Henrik
You need to determine whether it’s a keyboard issue or a board-related issue. Pull the keyboard cable and jump the laptop with the power-on pads on the board. If it stays on, you have a bad keyboard. If it still shuts off, you’re likely dealing with a board issue. The fact that “holding a key” allows it to stay on suggests you probably have a bad keyboard with a stuck key. Often in that case, holding in a key can temporarily counteract the effect of the stuck key.
