To install an upgrade CPU, do the following.
1. Make sure the handle on the side of the ZIF socket is up. To raise
the handle, push it down, slightly pull it out to the side, then raise it
as far as it will go. It may be necessary to initially apply a small
amount of sideways force to free the handle from its retaining " tab."
Once clear of the " tab," the handle will open relatively easily. The
top plate will slide back. Do not use screwdrivers or other tools to
open the socket, or you may damage the system or socket.
2. Once the lever is completely up, remove the old CPU carefully by
lifting it straight out of the socket. You are now ready to insert the
new CPU.
