clicking on keyboard does not end stand-by mode

[KWojcik]

hi, every time when my screen starts stand-by mode (gets dark) I wannot wake it up. Clicking power button does not work, clicking any button does not do anything- I can only press and do hard reset

@KWojcik, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand you're having trouble waking your HP Notebook from standby mode, the keyboard and power button don’t respond, and only a hard reset works. Let’s work through this together.

Perform a Hard Reset (if not already done)

This helps clear any temporary hardware or firmware glitches.

• Power off the notebook.
• Disconnect all external devices (USBs, printers, etc.).
• Unplug the AC adapter and remove the battery (if removable).
• Press and hold the power button for 15 seconds.
• Reconnect the battery and power adapter, then power on the notebook.

Update BIOS and Drivers

Outdated BIOS or chipset drivers can cause power management issues.

• Visit the HP Support page.
• Enter your notebook model number.
• Download and install the latest BIOS, chipset, and keyboard drivers.

Adjust Power Settings

Incorrect power settings may prevent the system from waking properly.

• Go to Control Panel > Power Options.
• Click Change plan settings next to your selected plan.
• Click Change advanced power settings.
• Expand Sleep > Allow hybrid sleep and set it to Off.
• Expand Power buttons and lid > Lid close action and Power button action, and set them to Sleep or Do nothing as needed.
• Click Apply and OK.

Check Device Manager for Keyboard Settings

Ensure the keyboard is allowed to wake the computer.

• Press Windows + X > Device Manager.
• Expand Keyboards, right-click your keyboard > Properties.
• Go to the Power Management tab.
• Check "Allow this device to wake the computer".
• Click OK.

Run HP Hardware Diagnostics

This checks for hardware issues.

• Turn off the notebook.
• Turn it back on and immediately press Esc repeatedly, then F2 to open HP PC Hardware Diagnostics.
• Run the Component Tests > Keyboard and Power tests. 

I hope this helps. 

Take care and have a good day.
