● ESD Packaging – All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded
bags are preferred. However, you should always return the damaged part using the same ESD bag and packaging that the
new part arrived in. The ESD bag should be folded over and taped shut and all the same foam packing material should be
used in the original box that the new part arrived in. ESD-sensitive devices should be removed from packaging only at an
ESD-protected work surface, and parts should never be placed on top of the ESD bag because only the inside of the bag is
shielded. Always place parts in your hand, on the ESD mat, in the computer, or inside an anti-static bag.
● Transporting Sensitive Components – When transporting ESD sensitive components such as replacement parts or parts
to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport.
ESD protection summary
It is recommended to always use the traditional wired ESD grounding wrist strap and protective anti-static mat when servicing
Dell products. In addition, it is critical to keep sensitive parts separate from all insulator parts while performing service and use
anti-static bags for transporting sensitive components.

BitLocker
CAUTION:
If BitLocker is not suspended before updating the BIOS, the next time you reboot the system it will
not recognize the BitLocker key. You will then be prompted to enter the recovery key to progress, and the
system will ask for the recovery key on each reboot. If the recovery key is not known, this can result in data loss
or an unnecessary operating system reinstall. For more information about this subject, see Knowledge Article:
