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.
NOTICE:
To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal
surface, such as a connector on the back of the computer.
NOTICE:
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 disconnecting a cable, pull on the cable's connector or on its strain-relief loop, not on the cable itself. For cable connectors with
release tabs, pull gently on the release tabs to release the connector. When connecting a cable, ensure that the connectors are correctly oriented
and aligned to avoid damage to the connector and/or the connector's pins.
NOTE:
Ensure that the computer is off and not in a power management mode. If you cannot shut down the computer using the operating system,
press and hold the power button for 4 seconds.
NOTICE:
To help prevent damage to the system board, you must remove the battery from the battery bay before you service the computer.
