Help with Acer E5-521 (Z5WAE LA-B232P)

[Slim_Boss]

Hey guys,
I come here to ask for your precious help.
I have an Acer E5-521 22P notebook (Z5WAE LA-232P motherboard).
He was stopped for 2 years, but now my wife needed him and I went to call, but when calling, I accessed everything, but there was no image on the LCD or on the external monitor. Through some forums I saw that they advised to update the bios.
So far so good, I took apart the PC and with the CH341A programmer I was able to read the BIOS and write a new one (I got the files from this post: https://www.badcaps.net/forum/showthread.php?t=71724)
However I noticed that there are 2 files, the BIOS and the EC.
After programming the BIOS, the notebook now only connects via the battery, but it still does not display an image (fan connection), in other words, the charger does not work.
Was it because I didn't program the EC? What chip are you going to have that file on?

I thank you in advance for any help that can be given. I send the backup of the bios.

Compliments,

Hi,
Thanks for the quick response.
So does it mean that even if you reprogram the BIOS (something I've already done), I don't have to mess with the EC?
This is because tonight I was trying to solve the whole night, I can program the BIOS through the CH341A (everything works fine), but after connecting the MB, it doesn't turn on (before it turned on but didn't give a picture), only if you put the battery in pc turns on, but also without image.

I would really like to retrieve this pc, because my wife needs it for work (although old for what she wants is enough).

Soory my bad English ...
