HP Omen 45L 4090 I9 13900
Microsoft Windows 11

Just got a new Omen 45L about 1 week ago. Pretty impressed overall with one concern.

 

If I apply all 4 settings in Windows 11 for power efficiency, the computer goes to sleep after 3 minutes.  My concern is that I will hear a click (same noise as when turning on computer on) every 1-3 minutes while in sleep mode.  The computer will wake up for 1-7 seconds and sometimes the case fans will spin for a couple seconds prior to going back to sleep mode.  My previous HP desktop is an 11-year old Phoenix on Windows 10 - so I don't have experience with a computer doing this before.  I suspect with the powerful GPU and CPU, maybe this is normal behavior to keep it cool in sleep mode?  Can anyone confirm?  Thanks for considering this question.

 

So far I have tried:

-plugged power cord into different outlet/surge protector

-updated bios from HP assistant

-ran it for a few days with 'never allow sleep mode' in power settings with no unusual behavior noted

Hi @jeremy399,

 

Welcome to HP Support Community.


Thank you for posting your query, I will be glad to help you.

 

The behavior you're describing seems unusual, and it's not a common behavior for a computer to wake up and go back to sleep repeatedly during normal sleep mode. It's possible that there may be some issues with power management settings, drivers, or potentially even the hardware. Here are some steps you can take to troubleshoot and address the issue.

 

  1. Check Power Management Settings: Ensure that your power management settings are configured correctly. Sometimes, certain devices or settings can trigger unnecessary wake-ups. Go to "Power & sleep settings" and make sure that the "Sleep" settings are configured appropriately.

  2. Update Drivers: Ensure that all your device drivers, especially those related to power management, are up to date. Visit the HP support website for your specific model and download the latest drivers for your system.

  3. Check Event Viewer: Use the Event Viewer in Windows to check for any events related to the waking up and sleeping of your computer. Look for events around the time your computer wakes up to see if there are any error messages or clues about what might be causing the behavior.

  4. Run Power Troubleshooter: Windows has a built-in Power Troubleshooter that can help identify and fix problems with power settings. To run it, go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Power.

  5. Disable Wake Timers: Sometimes, scheduled tasks or wake timers can cause the computer to wake up. You can disable wake timers by going to "Power Options" > "Change plan settings" > "Change advanced power settings" > "Sleep" > "Allow wake timers" and set it to "Disable."

  6. BIOS/UEFI Settings: Check your computer's BIOS/UEFI settings for any options related to power management or wake-on-LAN. Ensure that they are configured appropriately.

  7. Check for Background Processes: Some background processes or applications might be causing the wake-up. Check Task Manager for any processes that might be preventing the computer from going to sleep.

 

I hope this helps.

 

Take care and have a good day.

Hello Jeremy399, I had a similar experience with my new 45L i9-13900KF. Everything you mentioned happened to mine as well. HP informed me that it was the power supply and had me send it in for replacement. They replaced it, but the same issue occurred within the first week. I then contacted the Omen facility that fixed my PC, and the technician there said that this is what is supposed to happen and that the power supply did not need to be replaced. It still happens, but not as frequently, and I’m not sure why. They say it’s unusual, but I think it’s more widespread than they think.

I’m still experiencing other issues, especially with my RAM and new hard drives. I purchased a new SSD to add, and I was getting errors. They thought it was the new SSD, so I returned it and got another one from a different brand. Both were very good SSDs, but the issue persisted. Now they say it’s an operating system problem, so I’m supposed to reinstall the OS today. I have to back up and remove everything I’ve added, then update and reinstall everything and hope it’s back to the way it was except for the problem. I think they are giving out ‘Lemons’!

Goodluck with yours,

BKSOCAL

Hello Alden4,

Thank you for your detailed response and troubleshooting suggestions. I appreciate your efforts in providing a comprehensive guide to address the unusual behavior of the computer waking up and going back to sleep repeatedly during sleep mode.

I will follow the steps you've outlined and check the power management settings, update drivers, review the Event Viewer logs, run the Power Troubleshooter, disable wake timers, check BIOS/UEFI settings, and inspect background processes in Task Manager.

If I encounter any further issues or have additional questions, I'll be sure to reach out. Thanks again for your assistance.

Hello BKSOCAL,

I appreciate you sharing your experience with the HP Omen PC. It's concerning to hear about the recurring power supply issues and the ongoing challenges with RAM and new hard drives. It sounds like a frustrating situation. Reinstalling the OS might be a good step, but I understand the inconvenience it brings. If these issues persist, reaching out to HP support for further assistance or exploring warranty options could be beneficial.

It's possible that the PC's brief wake-ups in sleep mode are for maintenance, but if it occurs too frequently, checking power settings and consulting HP support would be advisable.

i have the same problem, did you find out what is the reason cause it? how to fix this issue?

HP Recommended

Had some of the same issues with my 45L.  I finally found out how to change from S0 sleep mode to S3 sleep mode.  That helped tremendously.  You can Google that info, so I will not repeat.

However, I think some issues might be caused by wireless issues.  I think my Logitech mouse reports battery level back to PC and I suspect that causes issue.

Here's my take:  Remove ALL devices from the PC, Ethernet cable, mouse, keyboard, even monitor, every cable and device except power and turn off blue tooth if you have it.  Let PC go to sleep on its own and see if PC wakes or has issues.  If works OK, then start plugging back items one at a time, letting them go 30 minutes before adding the next device. 

 

Sorry but I do not monitor the boards, so will have no further advice for you.  Good Luck.  It's a great machine.

I was having this same issue. I had to reset my CMOS (for other reasons), and that seems to have fixed the issue for me. No clue why. It shouldn't have, but it did.

 

To reset CMOS, you can either remove the battery on the mobo or remove the CMOS jumper on the mobo for 5 minutes and replace. The jumper method is easier on a 45L it seems.
