HP Notebook PCs - Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot

There are many reasons that a computer does not startup or boot into the Windows operating system. If your computer will not start or boot, you will see or hear symptoms to indicate the general area of the problem. If you are not sure what the problem is, see Overview of How to Troubleshoot Problems When a Computer Does Not Start Up or Boot Properly.
Startup Symptom: LEDs glow, but computer fails to startup or boot, and displays a black screen
Use this document if the LEDs glow to indicate that power is available and the sound of a fan or spinning hard drive can be heard, but no colors, images, or text are displayed on the LCD display.
Do not use this document if there are no sounds from the computer when the power is turned on. You should check for a different problem; such as a loose RAM memory chip or disconnected hard drive.
The cause of this problem may be the failure of a hardware component, or an error in the instruction being sent from the BIOS to a hardware component.
Before you begin troubleshooting your computer
Before you begin troubleshooting your computer, perform the following steps:
Step one: Perform a hard reset
If your computer suddenly fails to boot properly, you should perform a hard reset.
  1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds.
  3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Actions to take after performing hard reset
Black Screen with No Error Messages
If the display remains blank (black screen or white screen) after doing a hard reset, temporarily connect an external monitor to test the notebook's display. If an image displays on the external monitor, continue to perform the tests, install drivers, and make adjustments as described in the next section.
Test for hard drive problems
To test for hard drive problems, you can use the HP Hard Drive self test or HP PC Hardware Diagnostics (UEFI).
Test for hard drive problems using HP PC Hardware Diagnostics (UEFI)
There are six hard drive tests. If you think there is a problem with the hard drive, first try the Quick Test (about ten minutes). If the Quick Test does not find a problem, run the Extensive Test (2 hours or more). Follow these steps to run the Quick Test:
  1. Hold the power button for at least five seconds to turn off the computer.
  2. Turn on the computer and immediately press the F2 key repeatedly, about once every second.
  3. The HP PC Hardware Diagnostics (UEFI) home page displays.

     note:
    If your HP PC Hardware Diagnostics (UEFI) is older than the version used here, you can upgrade it to the latest version. For information on UEFI and installation instructions for the latest version, go to About UEFI and the Startup Menu.
  4. Select Component Tests from the list.

    The Hard Drive Quick Test begins. If the computer has more than one hard drive, you are asked to select a hard drive, or to test all the hard drives at once, select Test All Hard Drives.
  7. When test is complete the results are displayed on the screen. Test results can also be found in the Test Logs on the Main Menu.

    If the hard drive passes the Quick Test, but there is still a problem with the hard drive you can run the Extensive Test. This test includes the SMART Check, Short DST, Optimized DST, and Long DST.
     note:
    The Hard Drive Extensive Tests can be run individually by clicking a test in the Hard Drive Tests menu, and then clicking Run once.
    To run the Extensive Test, go to the next steps:
  8. Click Main Menu, select Component Test.
  9. Click Hard Drive, then click Extensive Test.
  10. Click Run Once.
    Figure : Clicking Run Once
    Clicking Run Once
    If the computer has more than one hard drive, you are asked to select a hard drive, or to test all the hard drives at once, select Test All Hard Drives. The Extensive Test runs all the tests listed on the screen for the drive selected. The Estimated Time Remaining is also shown.

  11. When the Extensive Test is complete, the results are displayed on the screen.
    If the hard drive fails one of the tests, write down the information so you have it available when you contact HP Support. The information is also available in the Test Logs on the Diagnostics UEFI Main Menu.
