• Problem: Incorrect characters are displayed on the screen.
Solution: Did you install the operating system or program correctly? If they are installed and configured
correctly, have the computer serviced.

Solution: Press and hold the power button for four seconds or more to turn off your computer; then
turn it on again.
• Problem: Missing, discolored, or bright dots appear on the screen every time you turn on your computer.
Solution: This is an intrinsic characteristic of the TFT technology. Your computer display contains
multiple thin-film transistors (TFTs). A small number of missing, discolored, or bright dots on the screen
might exist all the time.
• Problem: My screen keeps blanking when I do not want it to.
Solution: If your computer is preinstalled with the Windows 7 operating system, you can disable any
system timers, such as the LCD turn-off timer or the blank timer by doing the following:
1. Start Power Manager.
2. Click the Power plan tab, and then select Maximum Performance from the predefined power plans.
• Problem: When I turn on the computer, nothing is displayed on the screen and the computer does not
beep while starting up.
