The second step to opening the case usually involves finding the screws or other fasteners that keep the case closed. Some laptops may have screws on the bottom, sides, or back, while others may have push buttons, clips, or latches that you should unlock. It's necessary to adhere to the manufacturer's instructions while opening the case because some computers could require specific steps to be taken. To reduce the risk of electrical shock or component damage, turn off the computer and remove it from the socket before opening the case.
