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

CAUTION:
The memory modules are hot to the touch for some time after the
system has been powered down. Allow time for the memory modules to cool
before handling them. Handle the memory modules by the card edges and avoid
touching the components on the memory module.
