Resolving Problems with Sleep and Hibernate Modes (Windows 8)

  • PrintPrint
This document applies to HP and Compaq desktop and notebook computers with Windows 8.
Use this document to help resolve the following issues:
  • The computer wakes from sleep mode unexpectedly.
  • Pressing the sleep key on the keyboard does not put the computer to sleep.
  • Pressing the sleep button does not wake the computer.
    NOTE:If the sleep key on the keyboard fails to wake the computer, pressing the blinking power button on the front of the computer might wake the computer.
NOTE: If you are not using the latest version of Windows 8, some graphics and information in this document may vary. You can get the latest version from the Microsoft Store.

Understanding Sleep and Hibernate

Sleep: Pressing the Sleep key on the keyboard or clicking Sleep from the Windows 8 Shut down menu causes the computer to go into sleep mode. Closing the display panel on a notebook can also put the notebook in sleep mode. Sleep mode saves the state of all open programs to memory, then powers down both the display panel and hard disk drive. Only enough power is used to maintain the data in the memory. Restoring from Sleep mode happens quickly, in most cases in a matter of seconds. Sleep mode is useful when you need to pause the computer for a short time. However, in a notebook, maintaining the power to the memory modules can drain a battery if the notebook is not plugged in.
Hibernate: Clicking Hibernate from the Windows 8 Shut down menu (if available) causes the computer to go into the Hibernate mode. Hibernate saves the state of all open programs to the hard disk, then completely powers off the computer. The computer consumes no power while in hibernate mode. When you restart the computer, the previous state of all open programs is restored. Restarting from Hibernate mode might take longer than restarting from Sleep mode. Use hibernate when you do not need your computer for an extended period of time.

Activating Hibernate

Hibernate might not be available in the power button settings. Follow these instructions to active the hibernate option:
  1. At the Start screen type, Power Options and then select Power Options from the results list.

Special considerations for notebook computers

In addition to using standard power saving features available to all computers, notebook computers have a battery charging system. If a notebook is not connected to a power source for an extended period of time and the battery drops to less than ~10% charge, the computer can enter a sleep/suspend state and cannot be returned from sleep until the computer is connected to the AC adapter. The notebook does this to prevent data from being lost or corrupted during the working session. If you have a notebook computer that cannot return from sleep mode, first make sure it is connected to an AC power source and the power light is on.

Standard steps to resolve most sleep suspend problems

Use these steps to fix most sleep and suspend issues.

Step 1: Enabling the Keyboard

Skip this step if the computer does not enter sleep mode or if the computer wakes unexpectedly.
If pressing the sleep button on the keyboard does not wake the computer from sleep mode, it might be that the keyboard is not enabled to do so. Enable the keyboard as follows:
  1. At the Start screen type, Device Manager and then select Device Manager from the results list.
    Figure 5: Search
    Searching for device manager
  2. Click next to Keyboards and double-click the name of your keyboard.
    Figure 6: Device Manager
    Device manager with keyboard selected
  3. 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 if it appears below the Device status box. The same Keyboard 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.
  4. Click the Power Management tab and make sure that the box next to Allow this device to wake the computer is checked.
    Figure 7: Allow this device to wake the computer
    Selecting Allow this device to wake the computer
  5. Click OK . Test to make sure that the keyboard can now wake the computer. Continue using these steps if the computer still cannot wake from sleep mode.
    If Allow this device to wake the computer was already selected, continue using these steps.
    NOTE:To see if the keyboard supports sleep mode, follow these steps:
    1. Click the Details tab.
    2. Select Power data from the Property drop-down list.
    3. View the Power capabilities section to see exact function calls that are supported by the keyboard. If the keyboard cannot support a WAKE function, a connection problem exists or the device is incompatible.

Step 2: Changing device settings

Some device settings can cause the computer to return from a power savings 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. At the Start screen type, Device Manager and then select Device Manager from the results list.
    Figure 9: Search
    Searching for device manager
  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 . You might need to do this for each of the devices listed in the previous step, mice, keyboards, and sound.

  10. If the issue still exists, go to the next Step.

Step 3: Checking for a problem with a connected device

Some devices can cause sleep/standby issues. Use these steps to check for a problem with the devices connected to the computer.
  1. Disconnect all non-essential connected devices (printers, scanners, USB drives, etc.).
  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, go to the next Step.

Step 4: Checking for problems when the keyboard or mouse is using a USB 3.0 port

When using USB 3.0 ports, some computers don't wake from the keyboard or mouse, or you can't put the computer to sleep using the keyboard or mouse. Use these steps to check for a problem with the USB ports. This issue applied to systems using AMD firmware.
  1. Check the mouse and keyboard connections.
  2. If a USB 3.0 ports is used, reconnect the device to a USB 2.0 ports.
    If the issue still exists, go to the next Step.

Step 5: Using Microsoft System Restore

If sleep and hibernate modes previously worked, use System Restore to revert the computer back to a time when the mode worked. If the issue has always existed, skip this step.
NOTE:For more information on a given step, click the heading or the accompanying plus (+) sign to expand the information.
Perform a system restore to return the computer to a previous state when the sleep or hibernate mode worked.
