Important Safety Information
For your safety, never remove the PCs cover without first removing the power cord and any connection to a telecommunications network. Always replace the cover before switching the PC on again. For your safety, always connect equipment to a grounded electrical wall outlet. Always use a power cord with a properly grounded plug, such as the one provided with the equipment, or one in compliance with your national safety standards. The equipment can be disconnected from the power by removing the power cord from the power outlet. This means the equipment must be located close to an easily accessible electrical outlet. To avoid electric shock, do not open the Power Supply Unit. There are no serviceable parts inside. For your safety, only replace with a Power Supply Unit provided by HP Support Services. Ensure that the electrical power requirements of your PC (refer to the label on the Power Supply Unit) can be suitably provided by your electrical installation. There is a danger of explosion if the battery is incorrectly installed. For your safety, never attempt to recharge, disassemble or burn an old battery. Only replace the battery with the same or equivalent type, as recommended by the manufacturer. The battery in this PC is a lithium battery that does not contain any heavy metals. Nevertheless, in order to protect the environment, do not dispose of batteries in household waste. Please return used batteries either to the shop from which you bought them, or to the dealer from whom you purchased your PC, or to HP, so that they can either be recycled or disposed of in the correct way. Returned used batteries will be accepted free of charge. Do not attempt to connect this product to the phone line during a lightning storm. Never install telephone jacks in wet locations unless the telephone line has been disconnected at the network interface. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Use caution when installing or modifying telephone lines. Avoid using a telephone (other than a cordless type) during a lightning storm. There may be a risk from lightning. Do not use the telephone to report a gas leak in the vicinity of the leak. Never touch or remove the communications board without first removing the connection to the telephone network. Use minimum N 26 AWG wire for telephone cable.

Warning: some parts inside the computer may be hot. Please wait for them to cool down before touching them.
Choosing a Comfortable Workspace
Choose a workspace for your computer near a grounded electrical wall socket. If your monitor has a tiltswivel base, attach it to the monitor as described in the monitor manual. Position the monitor on your desk. Position the computer to allow proper ventilation and access to the cables.

WARNING

If you are in doubt that you can lift the equipment safely, do not try to move it without help.
