Troubleshooting Sleep and Hibernate issues (Windows 7)
This document pertains to HP computers with Windows 7.
The Sleep and Hibernate modes are power-saving states that greatly reduce the energy use of your PC while it is in use. The Sleep mode keeps your work and settings in memory, cutting energy use significantly, but allows you to return your PC to normal operation quickly.
Hibernate mode is a power-saving feature designed primarily for notebooks. While Sleep mode temporarily suspends your work and settings, drawing a small amount of power, Hibernate mode saves open documents and programs to the hard disk, and then powers down your PC. As Hibernate mode uses virtually no energy, it is the best option for conserving the battery power of your notebook.
When the Sleep and Hibernate functions are working properly, there are a number of ways, both manual and automatic, to make your PC Sleep or Hibernate. You can also customize how your computer enters each mode, or set up the computer so that it uses one mode exclusively.
Use the procedures in this document to resolve common issues with the Sleep and Hibernate modes.
The computer does not wake from Sleep or Hibernate mode
Restarting your computer when it does not wake from Sleep or Hibernate mode may restore functionality, but be aware that restarting erases all unsaved information. Before performing these steps, be sure to restart your computer to attempt to resolve the issue.
If you have a notebook computer that will not resume function from Sleep mode, first make sure it is connected to an AC power source and the power light is on.
Sleep or Hibernate issues on notebook computers can be caused by external devices connected to the notebook by USB drives. An external mouse or an external keyboard connected by USB may not be configured to wake a notebook from Sleep or Hibernate modes.
The following sections explain how to check for problems with a keyboard and mouse using USB ports, and how to enable your keyboard to wake your computer:
Checking the external keyboard and external mouse settings
Sometimes a keyboard or mouse connected to a USB 3.0 port can fail to wake the computer they are connected to, or fail to put the computer into sleep.
NOTE:
This issue applies to systems using AMD firmware.
To check for a problem with the USB ports, check the mouse and keyboard connections. If they are connected to a USB 3.0 port, reconnect the devices to a USB 2.0 port.
If the issue still exists, see The computer wakes from Sleep or Hibernate mode unexpectedly for instructions to disable HID-compliant devices.
Waking the computer with an external keyboard
An external keyboard connected to the computer by USB or Bluetooth can be enabled to wake the computer, or the option can be disabled.
NOTE:
The internal keyboard on an HP notebook can always wake the computer from Sleep or Hibernate. There is no option to toggle between enabling and disabling the waking function of an internal keyboard.
Use the following steps to enable an external keyboard to wake your computer from Sleep or Hibernate:
  1. Click Start
    , and then type Device Manager into the search field. Select Device Manager from the results list.

The computer wakes from Sleep or Hibernate mode unexpectedly
Interruptions to Sleep or Hibernate modes are often caused by software and external devices. The following sections describe how to check external devices, including HID-compliant devices, screen savers, and programs that may be responsible for waking the computer:
Checking the external devices connected to the computer
Just as devices like an external mouse or keyboard can be enabled to wake a computer from Sleep or Hibernate mode, external devices such as HID-compliant devices, SD cards, USB devices, or other peripherals can prevent the computer from staying in Sleep or Hibernate mode. To see if one of these devices is causing a problem, disconnect the device from the computer and then put the computer into Sleep or Hibernate. If you have multiple external devices or peripherals, disconnect them one by one and put the computer into Sleep or Hibernate mode each time. If one of the external devices is the source of the problem, then the problem should be resolved once you disconnect the device from the computer.
Use the following steps to check external devices for issues:
  1. Disconnect all non-essential connected devices (printers, scanners, USB drives).
  2. Restart the computer with only the original mouse, monitor, and keyboard connected.
    If this resolves the Sleep/standby issue, one of the connected devices was causing the problem. Replace one device and test to see if the issue occurs again. Continue adding devices and testing until you find the device that is causing the problem.
    If the issue still exists, proceed to the next section.
Configuring device settings
Some device settings can cause the computer to return from a power saving state unexpectedly. This can cause the computer to wake from Sleep mode for no apparent reason. Activity from devices such as a wireless mouse, network, or high definition audio can cause the computer to wake. Network activity can cause the network hardware to wake the computer, especially when the network is always on (like cable and DSL connections).
Use the following steps to prevent hardware devices from waking the computer:
  1. Click Start
    , and then type Device Manager into the search field. Select Device Manager from the results list.
  2. Click the arrow next to the device that needs to be adjusted.
    • If you are using an optical mouse, select Mice and other pointing devices.
    • If the computer is using an "always-on" Internet connection, select Network Adapters.
    • To check the high definition audio settings, click Sound, video, and game controllers.
  3. Double-click the name of the device to open a Properties window.
  4. If the Power Management tab is available, proceed to the next step.
    If the Power Management tab is not available, click the Change Settings button. The same Properties window opens with the Power Management tab available.
    If you are prompted for an Administrator password or confirmation, type the password or provide confirmation.
  5. Click the Power Management tab, and remove the check next to Allow this device to wake the computer.

    5. Select Off from the drop-down menu.
    6. Click OK.
If the issue still exists, proceed to the next section.
Using System Restore to resolve problems with Sleep or Hibernate mode
If Sleep or Hibernate mode previously worked but now is causing problems or does not work, use System Restore to revert the computer back to a time when those modes worked. If the problem has always existed, skip this section.
Use the following steps to perform a System Restore:
  1. Save any open files and close all programs. Backup any important files.
  2. Click Start, enter restore in the search field, and then select System Restore from the search result list.
  3. Select Choose a different restore point , and then click Next.
  4. Select a date from the list when Sleep or Hibernate mode worked correctly, and then click Next.
  5. Confirm the restore point, and then click Finish.
  6. Click Yes in the confirmation message that opens.
  7. The computer should shut down and turn back on automatically after the restoration completes.
  8. After the computer restarts, put it into Sleep or Hibernate mode to see if the problem still exists.
    • If after performing a System Restore the computer can enter Sleep or Hibernate mode, the problem is probably caused by software that was installed after the restore point date. Install the latest drivers and software one at a time and test the Sleep and Hibernate functions.
    • If the problem still exists, proceed to the next section.
Updating the BIOS to resolve problems with Sleep or Hibernate mode
