Omen 30L often does not wake up from sleep

[Dietlama]

Count me in on this, though mine is a brand new (less than a week) 25L - GT12-1340m.

If I can get it to sleep, which it usually just refuses to do after a quick screen flicker, it won't wake up. AND, after I manually power it off I get an error (from BIOS, I think) saying that one of the fans in malfunctioning. I'm fairly certain this is a false alarm (about the fan) as it only happens after powering off during sleep and then is fine after reboot (tested with various GPU benchmarks).

Not a great experience, coupled with the absolutely idiotic flashing light during sleep, and (day after I received it) disabled ability to turn off rainbow color-cycling on the RAM modules, I'm starting to regret my purchase. C'mon HP. It's great you're offering these machines, but the support isn't so great. So far.

Hi @Dietlama, 

Welcome to HP Support Community!

We noticed that this thread hasn't had any updates in a while since your original post; while this is rare, we didn't want this post to remain unanswered, so, here's the solution to your query. We hope it helps you and everyone viewing this post 😊

Here's a breakdown of what's likely happening and some steps you can try:

Common Causes & Fixes

1. Sleep/Wake Issues

• USB Power Management Conflict: Many users have resolved the wake issue by disabling power-saving features on USB controllers:

  • Open Device Manager (Win + R, type devmgmt.msc)
  • Expand Universal Serial Bus controllers
  • For each item (especially USB Root Hub and Intel(R) eXtensible Host Controller😞
    • Right-click → Properties → Power Management
    • Uncheck "Allow the computer to turn off this device to save power"
  • This has helped many users restore normal sleep/wake behavior .

• BIOS/Driver Updates: Ensure your BIOS and chipset drivers are fully up to date. HP has released firmware updates that address power management bugs.

• Disable Fast Startup:

  • Go to Control Panel > Power Options > Choose what the power buttons do
  • Click Change settings that are currently unavailable
  • Uncheck Turn on fast startup

2. Fan Error (90B) After Forced Shutdown

• This is likely a false positive triggered by the abrupt shutdown during sleep. The BIOS checks for fan RPMs on boot and may misread them if the system didn’t shut down cleanly.
• If the fan error disappears after a normal reboot and your system passes stress tests, it's safe to assume the fan is functioning correctly .

3. Sleep Refusal (Flicker and No Sleep)

• This could be caused by:
  • External devices (e.g., USB drives, peripherals)
  • Background processes or apps preventing sleep
  • Try running powercfg /requests in Command Prompt to see what’s blocking sleep.

Workarounds

• Disable Sleep Mode: If the issue persists and you don’t need sleep mode, consider disabling it entirely and using hibernate instead.
• Use Hibernate Instead:
  • powercfg -hibernate on (in Command Prompt as admin)
  • Set Hibernate as the default action for sleep in Power Options.
