Sleep and Hibernate issues after upgrading to Windows 10

If your computer does not go into sleep mode properly, the power light remains lit and the fan continues to run, running the Windows 10 Show or Hide Updates troubleshooter package might resolve the issue.

Step 1: Change the Windows Update Services setting

Change the Update Services setting from Automatic (Delayed Start) to Manual.

In Windows, search for and open the Control Panel.
In the Control Panel search field, type services, and then select Administrative Tools from the list.
Double-click Services, and then double-click Windows Update to view the properties.
Click Stop to stop the service from running.
From the Startup Type drop-down menu, and select Manual, then click OK.

Step 2: Install version 9 or 10 of the Intel Management Engine Interface (MEI) driver

To prepare to run the troubleshooter, make sure you have the correct version of the MEI driver installed.

Go to HP Drivers & Downloads.
Type the computer model number in the Enter your HP product name, product number or serial number box, for example, HP ProBook 645, and then click Find.

If a list of model numbers displays, select your model number from the list.
On the Software and driver results page, select Microsoft Windows 8.1 on the Version drop-down menu, and then click Change.
Download the MEI driver version 9 or 10 from the Driver-Chipset section.

If an MEI driver version 9 or 10 is not listed, download and install the appropriate driver from Intel (in English).

Download and run the Windows 10 Show or Hide Updates troubleshooter package.

Download the Windows 10 Show or Hide Updates (in English) troubleshooter package.
Run the troubleshooter package, and hide updates to the MEI driver.

Doing this blocks your system from automatically reinstalling or showing updates for version 11 of the MEI driver.

Step 4: Reset the Update Services setting

Use the previous steps to change Windows Update Services setting from Manual to Automatic (Delayed Start).

Step 5: Restart your computer

Restart your computer to complete the process.

The computer wakes from sleep mode unexpectedly

If your computer wakes from sleep mode unexpectedly, changing hardware device settings and scanning the computer for viruses might resolve the issue.

Step 1: Change device settings in Windows

Activity from hardware devices such as a wireless mouse, keyboards, network adapters, or high definition audio 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. Network activity can cause the network hardware to wake the computer, especially when the network is always on (for example, cable and DSL connections). Changing the hardware settings might resolve the issue.

In Windows, search for and open the Device Manager.
Click the arrow next to the device that needs to be adjusted.
- To check the keyboard settings, select Keyboards.
- If you are using an optical mouse, select Mice and other pointing devices.
  
  note:
  If you prevent the mouse from being able to wake the computer, you can still wake the computer by pressing the Space bar on the keyboard or the Power button on the front of the computer.
- 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.
Double-click the name of the device to open the Properties window.
Click the Power Management tab.
- 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.
Deselect the box next to Allow this device to wake the computer.
Click OK, close any open windows, and then restart the computer.
Repeat these steps for additional devices, if needed. You might need to do this for each of the devices listed: mice, keyboards, network adapters, and sound.

If the issue persists after changing hardware settings, continue to the next step.

Step 2: Check for a problem with a connected device

Some devices can cause sleep or standby issues. Disconnect the devices to test if they are causing the issue.

Disconnect all non-essential connected devices (printers, scanners, USB drives, etc.).
Restart the computer with only the original mouse, monitor, and keyboard connected.
- If disconnecting devices 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 persists after non-essential devices are disconnected, continue to the next step.

Step 3: Update antivirus software definitions and scan the computer for viruses

Some viruses and other malicious applications can cause sleep or hibernate issues. Update the antivirus software definitions, and then scan the computer for viruses.

note:
If antivirus software is not installed, HP recommends you install antivirus software.

For more information about updating antivirus applications and definitions and running a virus scan, go to Computer Might Be Infected by a Virus or Malware (Windows 10, 8).

If the unexpected waking issue still persists after any virus issues are resolved, or if the scan does not find any virus issues, continue to the next step.

Step 4: Scan for malware

Malware applications can cause sleep or hibernate issues. Using Windows Security (Windows 10) or Windows Defender (Windows 8) to scan the computer for malware might resolve the issue. These applications can prevent malware from infecting your computer in two ways:

Understanding Windows Sleep and Hibernate modes

Sleep: Press the Sleep key on the keyboard, or click Sleep from the Power menu (Windows 10), or under the Shut down menu in (Windows 8) to put the computer in 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 applications 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: Click Hibernate (if available) from the Power menu (Windows 10), or under the Shut down menu (Windows 8) to put the computer in hibernate mode. Hibernate saves the state of all open applications 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 applications 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.
