Desktop not waking up

[MG219]

Recently purchased HP Desktop 27cr0xxx.It goes into sleep mode ?  after sitting unused for an hour or so with the monitor light fading on and off and often will not wake up so I need to manually turn off then on again.This forced turning off can't be ideal?

I tried the suggestion of quickly turning off which worked once but not subsequently.

Hi @MG219,

Welcome to the HP Support Community.
 

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

You're right, having to manually power off your new HP Desktop 27-cr0xxx because it won’t wake from sleep mode is not ideal and could potentially lead to data loss or hardware stress over time.

Here’s how to fix it:

1. Enable Devices to Wake the Computer

Sometimes, the keyboard or mouse isn't allowed to wake the system from sleep.

• Open Device Manager.
• Expand Keyboards and Mice, and other pointing devices.
• Right-click each device > Properties > Power Management tab.
• Check “Allow this device to wake the computer”.
• Click OK.

2. Update Windows and HP Drivers

Outdated drivers or firmware can cause sleep/wake issues.

• Go to Settings > Windows Update > Check for updates.
• Also visit HP Support to update BIOS and chipset drivers: 👉 HP PCs - Sleep and Hibernate issues in Windows 10 | HP® Support 

3. Change Power Settings

Adjust sleep behavior to avoid deep sleep states.

• Go to Control Panel > Power Options.
• Select your current plan > Change plan settings > Change advanced power settings.
• Expand Sleep > Allow hybrid sleep → Set to Off.
• Expand PCI Express > Link State Power Management → Set to Off.
• Click Apply and OK.
   

4. Perform a Hard Reset

If the system is stuck, a hard reset can help:

• Shut down the PC.
• Unplug the power cable.
• Press and hold the power button for 15 seconds.
• Reconnect the power and turn it on.

I hope this helps.

Take care, and have an amazing day!
