System won't wake up from sleep mode

[patrickyc]

Every three or four days, I encounter an issue where my system will not wake up from sleep mode. I try moving the mouse and tapping keys on the keyboard, but the system does not respond. I end up having to restart manually by hitting the power button.

Thank you for joining HP Forums. 

I'll be glad to help you 🙂 

As I understand the system isn't waking up from sleep mode,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Did you install any recent Windows or Bios updates that could have caused this issue?

When was the last time it worked without these issues?

Did you perform a system restore to an earlier working date?

While you respond to that, Please follow the below steps to resolve your concern: 

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)

To try to resolve the issue, I performed a BIOS update a couple of days ago. So far, so good. Time will tell if the issue is fully resolved.

Hi

For about a week my HP Pavilion desktop 23-q105na will not awake from sleep mode

The fan comes on but the screen does not come and an it needs a hard reset (ie turn off and on) to get the screen back on. 

I've tried a few of the simple things mentioned before but it hasn't made a difference. 

I'm on Windows 10. Nothing new obviously upgraded to cause this to happen. 

Help please as this is really annoying!

My problem is fixed. It started Nov 2017 after 1 year from purchase.

I could hear the hard drive ticking away like my PC (all-in-one pavillion) was active but the screen would not come on properly.

The solution was to go into Device Manager and then Display Adaptors. I happen to have an AMD and Intel adaptor. I could see that Intel had updated a couple of times. So I updated the driver to an older version from my PC and it fixed the problem.

This solution cost me over £30 from HP support. Enjoy!

Can you please explain in more detail of where to look if I have an AMD & Intel adaptor and how to update driver using an older version.  I have the same trouble and tried a lot of different things and still have not fixed it. 

Thank you for your time.

I had a similar problem with my HP Pavilion laptop but had to do a lot of troubleshooting to really understand what was happening. At first I thought it was a 'sleep' issue but after tinkering around with the power options I realized it only affected the screen. Once the screen was powered down, nothing would power it back up although the HDD was still running as well as the cooling fan. I contacted HP support twice to fix this issue. The first support session took nearly two hours but ultimately did not resolve the issue. The second session seems to finally have resolved it. The fix was very odd. The technician changed the options for what the power button does from 'nothing' to 'shut down'. This fix makes no sense to me but so far the screen powers back on now after it has powered off after the preset idle time.

Need to look in Control Panel and then Devic manager. You'll see Display Adapters in there. Play about with it until you find the bit that allows you to go back to a previous driver.

I've tried all of the above on my Pavilion 17-g184cy, Windows 10 Pro X64 Redstone 4 .  My current workaround is to save all documents, close all apps, and shutdown every time I want to move the laptop.

By the way, USBs are not recognized by the laptop unless the BIOS has "legacy enabled" and the disk is formatted to MBR.

Thanks!
