The handle on the ZIF socket in your computer may not look identical to the handle shown in the
drawing. All handle types perform the same function.
To install a processor, complete the following steps:
1. Install the processor by lowering it into the ZIF socket. Ensure that pin 1 on the processor lines up
with pin 1 on the ZIF socket.
2. Push the handle on the ZIF socket back into place to secure the processor.
