Preparing to disassemble the computer

To avoid injury and equipment damage, always complete the following steps in order, when opening the HP
All-in-One.
1. Remove all media from the computer.
2. Shut down the computer.
3. After the system has completely shut down, disconnect the power adapter from the back of the
computer.
4. If a cable lock is installed on the rear of the unit, remove the lock.
5. Disconnect all other attached cables from the back of the computer.
6. Place the computer face down on a soft flat surface. HP recommends that you set down a blanket, towel,
or other soft cloth to protect the screen surface from scratches or other damage.
7. Since the computer screen is curved, be sure to stabilize the computer on a surface that is free of any
items that could damage the display. Be sure the display is secure before disassembly.
WARNING! Beware of sharp edges inside the chassis.
