How can you prevent damage to a component prior to touching it?
What will be an ideal response?
ANSWER: Before touching a component, first ground yourself using one of these methods:
*Wear an ESD strap around your wrist that clips onto the chassis or computer case, which eliminates any ESD between you and the chassis and its components.
*If you don't have an ESD strap handy, be sure to at least touch the case before you touch any component inside the case. This is not as effective as wearing an ESD strap, but can reduce the risk of ESD.
*To protect a sensitive component, always store it inside an antistatic bag when it's not in use.
In addition to protecting against ESD, always shut down and unplug a computer before working inside it.
