( If you want to know more about installation you can search and watch youtube videos)

All parts are brand new and some may be upgraded from the OEM versions.

This kit includes instructions and a component locations map.

 All parts should be fairly easy to identify on your board.

Identify the components and take note of the correct orientation of the original parts on your board to install them correctly.

The technician installing the parts is responsible for ordering the correct parts and installing

the parts correctly. Installation of parts will require the ability to read

the markings on your power supply board to locate the correct components to repair and install them correctly.

Improper handling could cause further damage to your board.

If you are not confident in your skills please hire a professional to perform the repairs.

Should take under an hour.
