HP 15-ef won't turn on

[Carlosarturoz]

I was using my laptop as usual and turn it off. The next day it won't turn on. The charger light is on and power led turns on for a half of a second but it does not do anything, the fans does not spin and it don't turn on the screen.

So far I have tried this:

Use another hp charger

Remove the battery, drain the system for a minute

Remove the m2 ssd

Change the position of the ram

Tried to turn it on without battery 

Tried to turn it on pressing windows + b 

With no success, this laptop has less than a year of use and I don't what more to try.

Hi@Carlosarturoz,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing issues with the HP Notebook not turning on and booting to windows just goes to a black screen. 

The BIOS can be corrupted during normal operation from a failed BIOS upgrade, or damage from a virus.   

Recover the BIOS using a key press combination.

Turn off the computer. Press and hold the Windows + b keys, and continue to press those keys while you press and hold the power button for 2 to 3 seconds. Release the power button, but continue pressing the Windows + b keys.

The power light remains on, and the screen remains blank for about 40 seconds before anything is displayed. You might hear a series of beeps (usually 8 beeps). Eventually, an HP BIOS Update screen is displayed and the BIOS update begins automatically.   

NOTE: If the HP BIOS Update screen is not displayed, press and release the power button, and then immediately press the Windows + b keys at the same time, repeatedly, until the computer beeps or opens the HP BIOS Update screen.

After the BIOS is recovered, a Continue Startup button is displayed and a timer counts down. Click the Continue Startup button to restart the computer immediately, or wait for the computer to restart automatically when the timer reaches zero.

If issue still persist then it could be a hardware issue on the PC.
