To avoid injury and equipment damage, always complete the following steps in order, when opening
the All-in-One.

Remove all removable media, such as compact discs or USB flash drives, from the computer.
2.
Turn off the computer properly through the operating system, then turn off any external devices.
3.
Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION:
Regardless of the power-on state, voltage is always present on the system board
as long as the system is plugged into an active AC outlet. You must disconnect the power cord
to avoid damage to the internal components of the computer.
4.

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.

Static electricity can damage the electronic components of the computer. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object.
