182 If Something Goes Wrong Resolving a hardware conflict A message displays saying that there is a problem with your display settings and that the adapter type is incorrect or the current settings do not work with your hardware. Reduce the size of the color palette to one that is supported by the computer's internal display. To change the display properties: 1 Right-click in a blank area of the Windows® desktop. 2 Click Personalize, and then Display Settings. 3 Adjust the screen resolution and/or color quality. 4 Click OK. The display mode is set to Simultaneous and the external display device does not work. Make sure the external monitor is capable of displaying at resolutions of 800 x 600 or higher. Devices that do not support this resolution will only work in Internal/External mode, and not simultaneous mode. Small bright dots appear on your TFT display when you turn on your computer. Small bright dots may appear on your screen display when you turn on your computer. Your display contains an extremely large number of thin-film transistors (TFT) and is manufactured using highprecision technology. Any small bright dots that may appear on your display are an intrinsic characteristic of the TFT manufacturing technology. Over a period of time, and depending on the usage of the computer, the brightness of the screen will deteriorate. This is also an intrinsic characteristic of the screen technology. When the computer is operated on battery power, the screen will dim and you may not be able to increase the brightness of the screen while on battery power. Disk or internal storage drive problems Problems with the internal storage drive or with a diskette drive usually show up as an inability to access the drive or as sector errors. Sometimes a drive problem may cause one or more files to appear to have garbage in them. Typical problems are: You are having trouble accessing a drive, or one or more files appear to be missing. Make sure you are identifying the drive by its correct name (A: or C:).
