HP Notebook PCs - Windows Device Manager Symbols, Error Codes, and Definitions in Windows 95, 98, Me, and XP

Before Beginning

Most problems can be resolved by restoring the original drivers which came with the notebook computer. If the computer is experiencing an issue with any of the original hardware that came in the notebook, it is recommneded that the original drivers be reinstalled.

This document applies to Microsoft Windows 95, 98, Me, and XP.

This document lists error codes reported in Device Manager and provides possible resolutions. It does not list error codes generated elsewhere, such as general protection faults, illegal operations, fatal exception errors, and beep codes.

Device Manager is a graphical user interface in Windows that stores information about the devices installed in the computer. This interface allows making changes to to the device properties. Device Manager stores the following information:

  • Installed hardware devices

  • IRQ ports

  • Memory allocations

  • Device driver

  • Whether the device is working properly

Device Manager error symbols

Device Manager uses the following symbols to provide information about a particular error condition with a specific system device:

Device Manager error symbol
Definition
Indicates the device is in a problem state. A device in a problem state can be functioning. A problem code explaining the problem is displayed for the device.
Indicates a disabled device. A disabled device is a device that is physically present in the system, consuming resources, but does not have a protected-mode driver loaded.
On a device resource in Computer properties, indicates that Use Automatic Settings is not selected for the device and that it was manually selected. It does not indicate a problem or a disabled device state.
This indicates that an exact (device-specific) driver is not available, and that a compatible driver has been installed. This new feature was implemented so that the device can be used, even if an exact driver is not available. Note that this applies only to Windows Millennium Edition (Me). Microsoft Knowledge Base article Q275012 Description of Green (yellow) Question Mark in Device Manager Non-HP site explains this issue.
