The power button on the PTAB7XC is made of plastic and frequently breaks; luckily, replacing the power button is a quick and easy process for even beginners.

你所需要的

1. 步骤 1 Power Button
  Remove the two 7 mm screws on the top of the device using a J00 Phillips screwdriver by turning them counterclockwise.
  
  If the screw heads have corroded or been stripped, it may be necessary to use a larger screwdriver head, such as the J0.
