Troubleshooting and Maintenance Getting Assistance for Your Notebook HP notebook TFT displays meet or exceed all HP standards for cosmetic quality of TFT displays. HP does not warrant that the displays will be free of cosmetic imperfections. TFT displays can have a small number of cosmetic imperfections and still conform to HP's cosmetic quality specifications, including the following: • No more than 6 pixels remain on (always one color, such as white, red, green, or blue dots). • No more than 6 pixels remain off (always dark). • No more than a total of 8 pixels stuck on or off. • No other stuck pixel within 15 mm of a stuck pixel. Contact HP Customer Care if you have a display quality problem and require a more comprehensive explanation of HP display quality-see "To contact HP for support or service" on page 131. We expect that over time the industry will continue to produce displays with fewer inherent cosmetic imperfections, and we will adjust our HP guidelines as these improvements are implemented. Floppy disk drive problems If a floppy drive connected to the USB port doesn't work • Make sure the drive is securely connected to the notebook. • Restart the notebook: click Start, Turn Off Computer, Restart. Hard disk drive problems If the notebook's hard drive doesn't spin • Make sure the notebook has power. If necessary, connect the AC adapter, and make sure it is fully plugged into a power source and into the back of the notebook. • Remove and reinsert the hard drive-see "To replace the hard disk drive" on page 95. If the hard disk makes a buzzing or whining noise • Back up the drive immediately. • See whether the noise is coming from elsewhere, such as the fan or a PC Card drive. Reference Guide 103
