HP 14-cf0014dx Boot Loop

[RussOnCrack]

I got a weird one in my opinions

Believe the laptop was shut off during a Bios Update. I've been trying to reset the Bios via Recovery USB

At first the laptop would show no sign of life other than 3 white flashes while unplugged. when plugged in it was solid yellow and a white flash every 5 ish seconds. took out the batter and turned it on with just the charger the fan started spinning and is boot looping every 5 seconds, with the battery in with charger it does the 3 white flashes and fans spin.
when I hold Windows + V the fans stop but it keeps boot looping. 
No display.

Hello @RussOnCrack 

The most important technical document for you:

Maintenance and Service Guide

General Information about your BIOS:

HP 14-ch0000, 14-cf0000, 15-da0000, 17-by0000 Laptop PCs - BIOS Simulator

In your case: Service is required !
- The computer should be disassembled and checked.
- Thermal paste for CPU GPU and bridges should be renewed
- The function of the fan(s) must be checked

- Short circuit test

- Bios chip reflash ( chip desoldering, chip programming, chip soldering )

- General cleaning ...

My recommendation

If you have no technical skill to do that, you should have it serviced by a professional notebook (chip level) repair store.

best regards
