Safety guidelines
While troubleshooting your computer, follow these safety guidelines:
■Never remove your computer cover.
■Do not attempt to open the monitor. To do so is extremely dangerous. Even if the power is disconnected, energy stored in the monitor components can be dangerous. Also, opening the monitor voids the warranty.
First steps
Try these things first before going to the following sections:
■Make sure the power cable is connected to your computer and an AC outlet and that the AC outlet is supplying power.
■If you use a power strip, make sure it is turned on.
■If a peripheral such as the keyboard or mouse does not work, disconnect and reconnect the device to make sure all connections are secure.
