Laptop will not wake up from sleep automatically.

[Kith2]

When I open my laptop lid now, it does not wake up automatically or by clicking the mouse or keys. I have to hold the power button for 10 seconds to wake it up. After this, it will wake up automatically but after some time it won't wake up automatically again. This is extremely annoying.

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

As I understand you are facing issues with sleep mode.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

How long are you facing this issue?

Did you try any troubleshooting steps before contacting us?

Meanwhile follow the steps given below:

Step 1: Enabling the Keyboard in Windows 

Skip this step if the computer does not enter sleep mode or if the computer wakes unexpectedly. 

Follow these steps to enable your keyboard to wake your computer from sleep mode: 

1. In Windows, search for and open the Device Manager. 

2. Click the arrow next to Keyboards and double-click the name of your keyboard. 

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. 

1. Click the Power Management tab and make sure that the box next to Allow this device to wake the computer is checked. 

2. Click OK, and then test to make sure that the keyboard can now wake the computer. If the computer still cannot wake from sleep mode, continue using these steps. 

3. For instructions on how to update the BIOS of your computer, see one of the following HP support documents: Updating the BIOS (Notebooks)
