CAUTION:
Before you begin any of the procedures in this section, follow the
safety instructions.
NOTICE:
Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not
covered by your warranty.
CAUTION:
Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a processor by its edges, not by its pins.
NOTICE:
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with
locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and
aligned.
NOTICE:
To avoid damaging the computer, perform the following steps before you begin working inside the computer.
NOTICE:
To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
CAUTION:
To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE:
Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
