To avoid damaging the computer's screws, use a small Phillips
screwdriver that is in good condition.
Installing a memory module with the computer's power on may
damage the computer, the module, or both.
The computer has two memory slots—Slot A and Slot B. You can
install one or two memory modules.
Before you install or remove a memory module, turn off the computer
using the Start menu. If you install or remove a memory module
while the computer is in Sleep or Hibernation mode, data will be lost.
For this model Slot A is the bottom slot. Slot B is the top slot. If only
one memory module is to be installed, it must be installed in slot A.
If the computer is on, begin at step 1; otherwise, skip to step 3.
