The Dimension 1100/B110 CR7H1 light means standby 5v power is available.

It does not mean that the power supply is good nor does it indicate that the computer is operating normally.

Identify the Computer Model Using the Model Code

On Sept 26, 2005 the System Setup program on certain Dell Dimension™, Inspiron™, and XPS™ computers was changed to display a model code instead of the computer model name. The Resource and Driver CD also lists the computer by this code. This may cause confusion when identifying which device drivers to install. If you are unable to identify your computer using the model code, refer to Table 1 below to determine the model name of your computer.
