Complete these advanced troubleshooting procedures to try to resolve startup issues with your notebook PC.

Troubleshoot specific startup issues

Find a symptom that matches your computer'due south status.

LED lights glimmer but the computer does non first

HP and Compaq notebook computers employ blinking LEDs to place startup errors. If the LEDs blink (usually ane to viii blinks in a serial) virtually the caps lock or num lock keys, get to HP Desktop PCs - Reckoner Does Not Get-go and Emits an LED or Beep Code.

Note:

If a white Ac adapter lite blinks when a new notebook computer is used for the first time, the bombardment is notwithstanding in Aircraft Mode. To resolve this issue, turn off the notebook, connect the notebook to Air-conditioning ability, permit the battery to accuse for at least thirty minutes, and then first the estimator.

The computer starts, only the screen is blank or unresponsive

When pressing the power button, LED lights blink or turn on, a fan spinning sound is heard, merely the screen remains blackness, and the notebook does not start.

If the reckoner is on, but the screen remains blank, go to HP Notebook PCs - Estimator Starts merely Screen Remains Blank (Windows 10, 8).

The computer does not have power (no noise or lights)

If there is no racket from the computer example or fans, the lights on the computer do non plough on (including keyboard LEDs), and the screen is non receiving a video betoken, your computer might non exist receiving power. Test the Ac adapter.

1. Confirm that the AC ability adapter is a genuine HP part. Practise not use a third-party AC ability adapter with an HP estimator.

   

2. Make up one's mind the adapter wattage by looking near the bottom of the adapter.

   Note:

   Using an Air-conditioning adapter with a lower wattage than the computer requires can crusade issues. For example, the CPU clock rate might be reduced to save ability, which might cause programs to run slower or the AC adapter to become warm to the bear upon.

   

   

3. Check the Air-conditioning power adapter for harm. Damaged components, similar the AC adapter housing or the pivot in the power connector, might crave an HP-certified repair. Bank check the box, string, pins, and plugs for harm.

4. Confirm that the wall outlet is functioning properly. Plug a lamp or device that yous know to be working into the same wall outlet y'all plan to use for the AC adapter.

   • If the lamp or other device works, the wall outlet is working correctly. Continue with these steps.

   • If the lamp or device does non piece of work, go along testing wall outlets until you find 1 that works, and then go along with these steps. Do non use a power strip, surge protector, or secondary power source.

5. Plug your Air conditioning adapter into the functioning wall outlet and start your computer. If the computer does not starting time, keep using these steps.

6. If y'all have access to a different AC adapter or power pack that is designed for the computer, connect information technology to the figurer and try to showtime the computer. If you have admission to more than one computer, confirm that y'all are using the right Air conditioning adapter.

   Caution:

   Use an Air-conditioning adapter that meets the power requirements and has the correct type of connector to avoid damaging the estimator. On newer notebook models, connecting the wrong adapter to the notebook might crusade the power LED lights to blink just not power on the calculator.

   If the computer does not start, go on with these steps.

7. Beginning the figurer. If the computer does not turn on, continue using these steps.

8. Remove the ability cord from the AC adapter for approximately 5 to ten seconds, then reconnect the power cord to the AC adapter. Make certain that the power cablevision fits tightly into the Ac adapter inlet.

9. Verify that all cords and connectors are secure between the ability cord, AC adapter, and reckoner. Beginning the estimator.

   If the computer does not turn on, go on with these steps.

10. Test for a discharged or defective bombardment that might prevent the Ac adapter from supplying enough power to start the computer. Remove the notebook battery, connect the AC adapter to the notebook, then turn on the computer.

    Startup problems and possible actions

    Condition	Possible action
    LEDs do not turn on, and the fan or difficult drive does non spin	The Ac adapter might demand to exist replaced
    LEDs turn on and computer starts	The battery might need to be replaced
    LEDs turn on but computer does not showtime	Go to HP Desktop PCs - Computer Does Not Kickoff and Emits an LED or Beep Code

    Note:

    Y'all can also try these steps with an alternate AC adapter that has the right wattage and connector.

    If the figurer does not turn on, continue with these steps.

11. Test for a defective AC adapter that might not charge the battery. This could forestall the computer from starting using just battery ability. Connect the Air-conditioning adapter, allow the reckoner to charge for 30 minutes or more, disconnect the AC adapter, and then try to start the figurer. This tin also exist done with a fully charged battery from some other computer.

    Startup issues and possible actions

    Condition	Possible activeness
