Omnibook 7 screen issue

[Mkong66]

Hi, I have a 2 month old omnibook 7. Today the screen just won't turn on. I have followed the hard reset routine and it didn't help. The screen is just black out, no error message whatsoever.

Hi @Mkong66 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand the concern. Since your HP OmniBook 7 is only about 2 months old, the power appears to come on but the display remains completely black even after performing a hard reset. 

Let's work through a few troubleshooting steps to help identify whether the issue is related to the display, graphics initialization, or startup process.

Verify the notebook is powered on:

• Connect the HP power adapter directly to a wall outlet.
• Press the power button once.
• Check whether the power LED, charging LED, keyboard backlight, or Caps Lock light turns on.

Check for display activity:

• Increase the screen brightness several times using the brightness keys.
• In a dim room, look closely at the screen for any faint HP logo, cursor, or backlight glow.

Force a graphics refresh:

• Press Windows + Ctrl + Shift + B together.
• If Windows is running in the background, you may hear a short beep and the display may refresh.

Test with an external monitor or TV:

• Connect an external display using the available video port.
• Press Windows + P a few times and wait several seconds between presses.
• If the external display works, the issue may be isolated to the notebook display assembly.

Perform a startup reset:

• Disconnect all external devices, including USB devices, printers, docking stations, and memory cards.
• Leave only the AC adapter connected.
• Turn the notebook on and observe for any light blink patterns from the Caps Lock or Power LED.

Check for diagnostic indicators:

• If the Caps Lock light blinks, note the number of blinks and whether the pattern repeats.
• Also let us know if the fan spins, keyboard backlight turns on, or if you hear any startup sounds.

Please share:

• The full HP OmniBook 7 model number.
• Whether the power LED is on.
• Any Caps Lock or Power LED blink pattern.
• Whether an external monitor shows a picture.
• Whether you hear the fan or Windows startup sounds.

These details will help us determine the next troubleshooting steps.

Take care, and have an amazing day!
