Troubleshooting from Device Manager is a process by which Microsoft Windows users diagnose and repair problematic hardware or components of their Personal Computer. The Device Manager is a Control Panel applet that gives a graphical view of the hardware installed on a computer.

Types of icons

Disabled device

A disabled device has either been manually disabled by a user or by some way of error. In Windows 7, this is denoted by a grey downward pointing arrow in the lower right-hand corner of the device's icon, or a red X in some older versions of Microsoft Windows.


Hardware not working properly

Hardware may not work properly for a multitude of reasons. If Windows recognizes a problem with a device, it is denoted by a black exclamation point (!) on a yellow triangle in the lower right-hand corner of the device's icon. <P> Hardware notworking

Hardware not recognized

Hardware may not be recognized if it is not installed properly or not compatible with your system. This is denoted by a yellow question mark in place of the device's icon. Notrecognized

Device manually selected

A blue "i" on a white field in the lower right-hand corner of a Device's icon indicates that the Use automatic settings feature is not selected for the device and that the resource was manually selected. Note that this does not indicate a problem or disabled state.
