Hi Adam,

Run the System Extensive Test
The System Test runs from the Startup menu. It checks the main components of your computer to make sure they are working properly. Use the following steps to run the System Test to check for problems.
  1. Press and hold the Power button until the computer turns off completely.
  2. Turn on the computer. Immediately press the Esc key repeatedly, about once every second, until the Startup Menu is displayed.
  3. Press the F2 key. The System Diagnostics screen is displayed.
  4. Click System Tests.System Tests
    The System Tests page opens.
  5. Click Extensive Test.

    The System Extensive Test window opens.

  6. Click Run Once. The test could take several hours, depending on the configuration of your system.
If a white LED for the AC power connector blinks when a new notebook computer is used for the first time, the battery is still in Shipping Mode. To resolve this, turn off the notebook, connect AC power and allow the battery to charge for at least 30 minutes, then start the computer.
Step 2: Connecting an external monitor to test the display
The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display back light. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

Step 3: Recovering the notebook BIOS using a key press combination 
When you upgrade the BIOS on your notebook, a copy of the previous BIOS version is stored in the HP_TOOLS partition of your hard drive. Many HP notebook computers have an emergency BIOS recovery feature that allows you to recover and install the last known good version of the BIOS from the hard drive, as long as the hard drive remains functional. This emergency recovery feature is separate from the BIOS and is designed to work in the event of a catastrophic BIOS failure.
Use these steps even if you cannot see anything on the monitor:
  1. Turn off the computer.
  2. Connect the notebook to a power source using the power adapter.
  3. Press and hold the Windows key and the B key at the same time while the computer is off.
  4. While still pressing the Windows key and the B key, hold down the Power button on the notebook for one second, and then release the Powerbutton and the keys.

    The power LED light remains on, and the screen remains blank for about 40 seconds. You might hear beeping sounds. Eventually, an HP BIOS Update screen displays, and the BIOS update begins automatically.

I hope this helps.

Regards,
Lokesh
