Hp 360 xpectre doesn’t turn on. Cap lock blinks

[mishellechayeb]

I was watching movies in my computer and my battery died. It doesn’t turn on anymore. The screen is black and the cap lock blinks with a white light 5 times slow and 3 times fast.

What should I do?

Thank you for posting on the HP Support Community.

I have a few troubleshooting steps we could try to fix the issue:  
Let's try these steps -

Hard Reset -

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery. ( not for Built-in Battery computer ) 

4) Press and hold down the power button for 15 to 20 seconds.  

5) Plug-in the Adapter and put the Battery back into the computer if it's a (removable battery)

6) Try to turn on the computer and check, If the issue persists continue next step

Set BIOS default and restart:

1. Restart your notebook.
2. During startup, press F10 repeatedly until the BIOS menu is displayed.
3. Once the BIOS menu is displayed, press F9 to restore factory defaults.
4. Select Yes to confirm.
5. Press F10 to save changes and exit.
6. Select Yes to confirm.
7. The computer restarts using the default settings.

Hope this helps! Keep me posted for further assistance.

Hi Echo,

Your suggestions have not worked. I also tried to update the BIOS through a USB stick but the computer´s caps lock has the same behaviour 5 slow/3 fast blinks + black screen, no beeps.

What should I do?
