Common procedures
Grounding yourself
Note Even if the power has been turned off from the PC, as long as the mains cable is connected to the
PSU (and power is provided) the +5 StandBy voltage is provided to the system for some crucial
components. Therefore hardware is sensitive to static electricity.
Before touching circuit boards or other devices inside the system unit, be sure to get rid of any static charge you
may have by grounding yourself properly. At a minimum, before touching a circuit board, first touch the metal
part of the chassis. However, there is a safer way to do this, and the following describes how you should ideally
ground yourself :
1. Connect the metal chassis of your computer to a grounded metal object such as a radiator:

2. Ground yourself to any grounded metal object by first attaching a wrist strap made for this purpose
around your wrist and then to the metal object:

3. Now you can touch the devices inside your system unit.
