HP Compaq 6730s Notebook PC Maintenance and Service Guide PDF Manual
Electrostatic discharge damage. Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases, ESD contains enough power to alter HP laptop parameters or melt silicon junctions. A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a normal cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life expectancy. Before removing the display assembly, follow these steps:
1. Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system.
2. Disconnect all external devices connected to the computer.
3. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then unplugging the AC adapter from the computer.
4. Remove the battery (see Battery on page 50).
5. Remove the following components:
a. Switch cover and keyboard (see Switch cover and keyboard on page 61)
b. Speakers (see Speakers on page 66)

Here is some tips and trouble shooting when you faced the problem with your Dell XPS 8300 Series. If the power light is off, firmly press the button to ensure that the monitor is turned on. If the power light is lit or blinking, the monitor has power. If the power light is blinking, press a key on the keyboard or move the mouse. Check the connector for bent or broken pins. (It is normal for monitor cable connectors to have missing pins.) Ensure that the video cable is connected as shown on the Start Here setup diagram for your computer.
Ensure that the electrical outlet is working by testing it with another device, such as a lamp. Swap the Dell computer and monitor power cables to determine if the power cable is defective. If you are using a video extension cable and removing the cable solves the problem, the cable is defective. If another monitor is available, connect it to the computer.
