HP PCs - Device Manager Information (Windows 10, 8)

This document applies to HP and Compaq computers and tablets with Windows 10 or Windows 8.
This document contains information about using the Device Manager utility and information about Device Manager error codes.
Depending on your version of Windows, some graphics and information in this document might vary slightly.
note:
You must be logged on as an administrator to change settings in Device Manager. Non-administrator user accounts can view settings, but not make changes.
Device Manager stores information about the devices installed in the computer, for example:
  • Installed hardware devices
  • Whether the device is working properly and gives error messages if it is not
  • IRQ ports
  • Memory allocations
  • Device driver
Device Manager allows you to change the driver properties used by the computer hardware.

Opening Device Manager to view error codes

To view error codes in Device Manager, follow these steps:
  1. In Windows, search for and open Device Manager.
  2. Select Device Manager in the menu.
    Figure : Device Manager
    Device Manager
  3. Double-click a device type (for example, double-click Display Adapters) to view the devices in that category.
  4. Right-click the desired device and click Properties.

  • The scroll box at the bottom contains a Conflicting device list. If a conflict is occurring, an error code is displayed on this list.
  • When Windows successfully detects a device, the Use automatic settings check box is selected. The device should function correctly.
  • If the resource settings for a device are based on Basic Configuration <n> (where <n> is any number from 0000 to 0009), it is possible to change the configuration by selecting a different Resource setting from the list.
  • If the settings for the device are not based on a Basic Configuration, click the Change Setting button and manually adjust the resource values. For example, to edit the Input/Output Range setting, use these steps:
    1. Click the Use automatic settings check box to clear it.
    2. Click the Change Setting button.
    3. Click the appropriate I/O range for the device.
    4. Save the new setting and click OK to exit.
    5. Restart the computer for the new settings to be recognized.

Device Manager error symbols

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

Detailed error code information
