HP Notebook PCs - Advanced startup troubleshooting (Windows 10)

Complete these avant-garde troubleshooting procedures to try to resolve startup issues with your notebook PC.

Troubleshoot specific startup issues

Notice a symptom that matches your calculator's condition.

LED lights blink merely the computer does not start

HP and Compaq notebook computers use blinking LEDs to identify startup errors. If the LEDs blink (usually 1 to 8 blinks in a series) near the caps lock or num lock keys, get to HP Desktop PCs - Computer Does Non Get-go and Emits an LED or Beep Lawmaking.

Note:

If a white Ac adapter calorie-free blinks when a new notebook computer is used for the first time, the battery is notwithstanding in Shipping Mode. To resolve this issue, turn off the notebook, connect the notebook to AC ability, allow the battery to charge for at least 30 minutes, and so commencement the computer.

The reckoner starts, but the screen is blank or unresponsive

When pressing the power push, LED lights glimmer or turn on, a fan spinning sound is heard, just the screen remains black, and the notebook does not first.

If the computer is on, merely the screen remains blank, go to HP Notebook PCs - Computer Starts but Screen Remains Bare (Windows x, viii).

The computer does not accept power (no dissonance or lights)

If in that location is no dissonance from the computer instance or fans, the lights on the computer do non turn on (including keyboard LEDs), and the screen is not receiving a video betoken, your computer might not exist receiving power. Test the AC adapter.

1. Confirm that the Air conditioning power adapter is a genuine HP part. Practice non utilise a 3rd-political party Ac power adapter with an HP computer.

   

2. Determine the adapter wattage past looking about the bottom of the adapter.

   Note:

   Using an AC adapter with a lower wattage than the figurer requires can cause bug. For instance, the CPU clock rate might be reduced to save power, which might cause programs to run slower or the Air-conditioning adapter to get warm to the affect.

   

   

3. Check the Air conditioning power adapter for damage. Damaged components, like the AC adapter housing or the pin in the ability connector, might require an HP-certified repair. Check the box, cord, pins, and plugs for damage.

4. Confirm that the wall outlet is operation properly. Plug a lamp or device that you know to be working into the same wall outlet you plan to use for the AC adapter.

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

   • If the lamp or device does not work, keep testing wall outlets until you notice one that works, and and then continue with these steps. Practise not use a power strip, surge protector, or secondary power source.

5. Plug your AC adapter into the performance wall outlet and starting time your reckoner. If the figurer does not get-go, continue using these steps.

6. If y'all have access to a different Ac adapter or power pack that is designed for the figurer, connect it to the computer and attempt to showtime the computer. If yous take access to more than one calculator, confirm that you are using the correct Ac adapter.

   CAUTION:

   Use an AC adapter that meets the power requirements and has the correct type of connector to avoid damaging the computer. On newer notebook models, connecting the wrong adapter to the notebook might cause the power LED lights to glimmer only non power on the computer.

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

7. Start the calculator. If the computer does not plow on, go along using these steps.

8. Remove the ability cord from the Air conditioning adapter for approximately five to 10 seconds, and so reconnect the power cord to the AC adapter. Brand sure that the power cable fits tightly into the Ac adapter inlet.
