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

    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,

      the EC bios is for the I/O chip...

          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 ...

              Acer Aspire 5920G - Requesting Modded BIOS (9600M GT) from .WPH for CH341A Flasher
              by EbrahimSiami
              Hello everyone,
              I need help with my Acer Aspire 5920G laptop. Its original GeForce 8600M GT graphics card failed, so I replaced it with an Nvidia GeForce 9600M GT MXM card.

              **Problem:** The laptop powers on, but there is no display (black screen) on either the internal LCD or external monitor. This indicates a BIOS compatibility issue with the new graphics card.

              **What I have tried so far:**
              1. I have my **original stock BIOS dump (1MB .BIN file)** from my laptop, which works and allows the laptop to power on normally (but no display with 9600M...

              🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
              by macabook
              Hello everyone,

              I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
              🧩 Initial Issue
              • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
              • External display (HDMI) shows
              ...

              Acer Nitro 50-640E Corrupted BIOS Dump
              by James194zt
              Hi,

              My daughter has accidentally managed to kill her Acer gaming desktop it has a blank screen after updating and when you press the power button the fans spin, light comes on and it makes 1 long and 1 short beep and no attempt to boot.

              All basic troubleshooting has been done we replaced CPU, GPU and RAM from a working machine and no joy, I also noticed a post on here with the same issue and it was the BIOS. I am pretty sure also because it was doing a BIOS update that stopped it working, she knocked the keyboard out by accident during the update and the screen just went...
