Sorry, I changed the post, this is the correct one.
Below is the same post:

Thanks HOACA388 for your help.
But the notebook is still working with a black screen.
I've writeen both BIOS. When connecting the power supply or internal battery, the laptop starts, caps lock turns on, blinks twice, after a few seconds it turns off and then restarts the cycle indefinitely.
I waited 30 minutes when turning it on for the first time. The fans is working normally now but the keyboard is inoperative. The power led lights up for a few moments.
I would appreciate any...

Thanks Shiyab, I tried both but they won't work, laptop won't turn on.
In fact this was the initial defect.
With others bios that I tested the laptop turns on and fans at max speed.
I opened both (8MB - original and sent) with ME Analyzer 1.304 and they show errors (attachments).
I still need help!!​...

DELL G3 15 3500 - SELEK 19753-1 Service Tag: 6HMQ0D3
It worked normally, after testing it turns on but no display, fans works at max speed.
I tested others bios without success.
Please help to fix my bios files.​...
