MY ALL-IN-ONE COMPUTER WON'T BOOT UP

[RodneyS3]

My HP 23.8"  Touchscreen All-in-One, purchased in October 2023, recently has experienced boot-up issues from either sleep mode or when it is shut down. This morning, it took several minutes for it to finally boot-up after I pressed the power button. I tried the hard reset, but that did not work. 

What should I do next?

@RodneyS3, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand your HP 23.8" Touchscreen All-in-One, is having trouble booting up especially from sleep mode or after shutdown. Let's walk through some steps to help resolve this issue.

Perform a Hard Reset (if not already done)

This helps clear any residual power and reset hardware connections.

1. Turn off the computer completely.
2. Disconnect the power cord from the back of the PC.
3. Press and hold the Power button for 15–20 seconds.
4. Reconnect the power cord and try turning the PC back on.

Disable Fast Startup (Windows 11)

Fast Startup can sometimes cause boot issues.

1. Press Windows + X and select Power Options.
2. Click Additional power settings > Choose what the power buttons do.
3. Click Change settings that are currently unavailable.
4. Uncheck Turn on fast startup (recommended).
5. Click Save changes and restart your PC.

Update BIOS and Drivers

Outdated firmware or drivers can cause boot delays.

• Visit the HP Support Page.
• Enter your product name or serial number.
• Download and install the latest BIOS, chipset, and graphics drivers.

Run HP Hardware Diagnostics

To rule out hardware issues:

1. Turn off the PC.
2. Turn it back on and immediately press F2 repeatedly.
3. Select System Tests > Quick Test or Extensive Test.

Check for Windows Updates

Make sure your system is fully updated:

• Go to Settings > Windows Update and install all available updates.

Thanks very much, Max.  However, when I select "Power Options" I do not see "Additional power settings."

For the time being, I am not shutting down my computer at night.  Could it be that a recent Windows update is what caused the problem and that will be corrected in the next update?

Also, would choosing "hibernate" rather than "sleep" when I log off at night possibly avoid the long boot-up time?

Thanks,

Rodney

Hi @RodneyS3, Thanks for the follow-up! You're asking some great questions, let’s address each one and help you move forward.

Missing “Additional Power Settings”

If you don’t see “Additional power settings”, try this alternate path:

1. Press Windows + R, type control, and hit Enter to open the Control Panel.
2. Go to Hardware and Sound > Power Options.
3. On the left pane, click “Choose what the power buttons do”.
4. Then click “Change settings that are currently unavailable”.
5. Uncheck “Turn on fast startup (recommended)”, then Save changes.

This setting is known to cause boot delays on some systems.

Could a Windows Update Be the Cause?

Yes, it’s quite possible. Windows updates occasionally introduce bugs that affect boot behavior, especially with sleep/hibernate modes. If this started recently, it may be linked to a recent update. Microsoft often releases fixes in subsequent updates, so keeping your system updated is a good idea.

You can check your update history via:

• Settings > Windows Update > Update history

If you suspect a specific update, you can also uninstall it temporarily.

Hibernate vs Sleep

Choosing Hibernate instead of Sleep can be a smart workaround.

• Sleep keeps your session in RAM, which can sometimes cause wake-up issues.
• Hibernate saves your session to disk and powers off the system, more stable for overnight use.

To enable Hibernate:

1. Open Control Panel > Power Options.
2. Click “Choose what the power buttons do”.
3. Click “Change settings that are currently unavailable”.
4. Check “Hibernate” under shutdown options.

Then, when logging off at night, choose Hibernate from the Start menu power options.

I hope this helps!
