UNSOLVED
Power sequencing fail
A long time ago, I spilled water on my laptop, later I opened it and tested with a voltimeter, everything seemed fine except the power button board, so I bought a new one. Now the laptop starts and doesnt turn off after some time like it did before, but nothing appears on screen, only the keyboard lits up and the LED shows me the code error, I can also hear the fans working, and thats it.
No results, the screen was just total black, I tried connecting to another monitor but still nothing. However, I remember now that a connector labeled as KB was broken, one of those "black strings" you connect. Since i think KB means "keyboard", I connected the laptop to an external keyboard, but still nothing

Welcome to the Dell Community @CarthusK
Hold down the "D" key, push the power button, release the power button, wait 2-3 seconds and release the "D" key
The laptop should go through an LCD test of solid White, Red, Green, Blue and Black 2 or 3 times.
After completion it should try to automatically boot 2 or 3 times.
Post your results.
Best regards,
