  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.
WARNING: 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.
