Here are two methods that we can try to fix "Power ON – No-Display Issue" Issue.

Method 1: Release the electrostatic charge
1. Check whether the connection between the power adapter and the computer is proper. Unplug and plug in again and power up.

2. Disconnect the AC Adapter and all the peripherals on the unit. (If there is a removable battery, please remove).

3. When the external power supply is normal, press and hold the Power ON button for 10 seconds to release the electrostatic charge. (Note: this is only suitable for models released after the year 2017.

4. Plug in the AC adapter and Power ON your computer after completing the steps mentioned above.

Method 2: Restore the BIOS
If the problem persists after the electrostatic charge was released, for example, if you notice the Power ON button is blinking up to 8 times, you may proceed to solve this via BIOS recovery.

Note: Please backup all your important data before doing this

Scenario 1: BIOS recovery via key combination

  1. Press the ‘Windows’ key and the ‘B’ key at the same time
  2. Don't release the keys. At the same time, press the Power ON button for 2 to 3 seconds, and then release the Power ON button; but continue pressing the ‘Windows’ and ‘B’ keys.
  3. If it works, the Power ON LED button will lit up and your screen will remain blank for about 40 seconds. After that, you will see contents being shown on your screen. You may hear some beeping sound throughout this period. In the end, a screen showing “HP BIOS Update” will pop up and your computer will automatically update the BIOS.
  4.   Once the BIOS has been recovered, the [Continue Startup] will be displayed, and a timer will begin to countdown. Click the [Continue Startup] to restart the computer immediately, or automatically restart the computer when the timer reaches zero.
  5.  When the computer restarts, it will display a blank screen with the following messages:
  • System BIOS recovery has completed - BIOS Recovery (500) - Enter – to continue
    At this point, press Enter to startup immediately, or allow the computer to restart automatically
  • Scenario 2: BIOS recovery using USB recovery drive

    If the steps in Scenario-1 didn’t work, we still have other ways to do so.
    Another option: Download the BIOS using another Internet-connected computer, to create a USB recovery drive, and install it on your computer.


    Step 1: Create A USB Recovery Drive

    1. Find the Product Number and Model Number of the computer which is required for BIOS recovery. This information is usually stated on the label located at the back / side / box of the computer.
    2. Insert an empty USB disk into the USB port of another Internet-connected computer.
    3. Visit the HP Customer Support-Software and Driver Downloads at https://support.hp.com/cn-en/drivers page.
    4. Navigate to the page where it contains information of your computer.
    5. Select the BIOS and carefully review the details of the latest or recommended version for recovery. You must ensure that it is the correct file for BIOS Update before proceeding.
    6. Click [Download], and then click [Run]. Click [Yes] on the "User Account Control" screen.
    7. In the Installation Wizard window, click [Next]. Select [I accept the terms in the license agreement], and then click [Next].
    8. Select [Create USB Recovery Flash Drive], and then click [Next].
    9. Select the USB flash drive, and depending on the file system type
      a) FAT32: Click [Next]. & b) exFAT, NTFS or other types: Click [Format].
    10.  Wait patiently for the BIOS file to be copied to the drive.
    11. When the message [Successfully created recovery flash disk] is displayed, click [Finish].
    12.  Remove the USB drive from this computer.

    Step 2: Install the BIOS recovery file

    After the USB Recovery Drive is created, follow the steps below.

    1. Shutdown your computer and wait for 5 to 10 seconds.
    2. Insert the USB Drive into the USB port of your computer.
    3. Press and hold the “Windows+B” combination keys at the same time, and then press and hold the Power ON button for 2 to 3 seconds.
    4. Release the Power ON button but don’t release the “Windows+B” keys.
    The HP BIOS update windows will be displayed, and the BIOS will start to recover automatically. Just follow the on-screen instructions until completion

If the issue still persists please contact HP support.
