[cristiannec]

try. on first boot be patient. reset security setting to defaults.

Hello
This bios reacts the same way as bios patched by me. Nothing happens when i press power button, not even the charger switch to 20v.

Bios patched by @minhdigital starts, charger switch to 20volts, then sistem shuts down and restarts loop.

Checked everything again,wrote each bin again and :

- original bios everything works fine, just has bios password so board is fine.

- Bios from minhdigital stays on ~10 sec , then boot loop 1 sec on 1 sec off .

- Bios from rex98 nothing happens, when i press power button i get amber light as long as the hold the button pressed. Charger does not switch from to 5 to 20.

write again bios file provided by rex98, check soldering, at 1st start wait for 2 minutes, it will restart several times with no image.

Replaced flash memory today, tried again, and :

- Bios from rex98 starts , no image , and led flashes 3 amber 6 white.

- Bios from minhdigital starts,after 2min display starts and dell logo appears for half a second, then system restarts continiously without an ending. (flashed it few times same result)

Maybe there`s a hardware problem .The laptop is still under warranty = ProSupport Flex ⦁ Expires 18 NOV 2025

Don't think it's hardware issue, works fine with original dump, but has password.
