Regardless of the power- on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board. If you see an LED light on the system board, voltage is still present.
5.Remove the computer access panel.
6.Locate the memory module sockets on the system board.
