19 Connect your computer and devices to electrical outlets, and turn them
on.
20 Press <F2> to enter system setup and check the values listed under
Memory Info.
The computer should have changed the value of
Installed Memory to
reflect the newly installed memory. Verify the new total. If it is correct, skip
to step 22.
21 If the memory total is incorrect, turn off and disconnect your computer
and devices from their electrical outlets.
Return to step 1 of this procedure, but instead of installing new memory,
check the installed memory modules to ensure that they are seated
properly in their sockets.
22 When the Installed Memory total is correct, press <Esc> to exit system
setup.
23 Run the Dell Diagnostics to verify that the memory modules are operating
properly. See "Dell Diagnostics" on page 123.

other important safety information.
CAUTION:
The computer stand should be installed at all times to ensure
maximum system stability. Failure to install the stand could result in the computer
