•
You have read the safety information that shipped with your computer.
•
A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.
About this task
NOTE:
Disconnect all power sources before opening the computer cover or panels. After you finish working inside the
computer, replace all covers, panels, and screws before connecting to the power source.
WARNING:
Before working inside your computer, read the safety information that shipped with your computer. For
additional safety best practices information, see the
Regulatory Compliance Homepage
CAUTION:
Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow
the safety instructions that came with the product.
CAUTION:
To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching
an unpainted metal surface at the same time as touching a connector on the back of the computer.
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.
CAUTION:
When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables
have connectors 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.
NOTE:
The color of your computer and certain components may appear differently than shown in this document.

2. Connect the device to a charger and then turn it on.
3. Hold Refresh

keys at the same time.
4. While holding these keys, remove the power cable from the device and then release the keys. The device should shut down and
