Manual Ejection Mechanism
All optical units have a manual ejection mechanism, where you can open the drive tray even with the computer turned off or with the drive out of the PC. This is a very old trick, but we will need to use it to open our optical unit. First, locate the manual ejection hole on the front of the unit.
Then get a paper clip, open it and insert it in the hole, like shown in Figure 3.
You will feel some resistance. Push it until the tray is a little bit open, as shown in Figure 4.
Then, just pull the tray with your hands to open it completely.
Now let’s open the optical unit.
