Acer one 14 Z8-415 BIOS update fail

My Acer One 14 Z8-415 has an annoying shutdown issue. Later, I found on Google that it’s likely a BIOS issue, so I downloaded the BIOS update from the Acer website. I ran the .exe file after unzipping the downloaded file.

During the BIOS update process, I noticed it first erased the old BIOS before loading the new one. After it finished, the command window closed automatically. I ran the .exe file again, but when it tried to erase the BIOS, my laptop shut off and now won’t turn on. It only shows a black screen and a blue power LED. I’ve checked, and the USB ports still have power.

I’ve tried everything to reset the BIOS/CMOS, including removing the main battery and the CMOS battery from the motherboard, then holding the power button for 1 to 2 minutes. But the laptop still won’t turn on—just a black screen.

Can anyone help me fix this?

You may try this… it may not be a useful method for every Acer laptop system or modern ones and/or Phoenix/H2Oinsyde.
Other options… IC SPI programmer or pay to an IT Tech Shop or request Acer India support for recover method details witch i doubt that will even bother with it.

EDIT:

I’ve not found the product download page and i didn’t waste my time looking for it.
You should post the link product support page, machine ID/SN or link to bios file.

We don’t want your private files or your data, whether you share it or not and i didnt ask for any private file with Access Request on GDrive.
As mentioned before, you could simply link the product page support or the original Acer bios update file.

The BIOS is no longer available on the Acer support page, but I had previously downloaded it from there. You can download it using the following link.

Strange…very strange, a not so old model with a 11th Gen 1115G4.

The contents of the package have a CRISIS folder, you should try to use this file on a USB drive.
This is usally the file for recover.
Some bios corruptions/failed updates can lead to a malfunction of any automatic recovery methods or the system EC region.
You need to look for info about the correct procedure on this laptop model to trigger the automatic recover, its not always equal to all vendors or systems generations
Thats all i can help, good luck.

Hi MeatWar,

Thank you for your reply. I’m not even a beginner in this area, so I’m still figuring things out. You suggested trying the CRISIS file, but I’m not sure how to use it, and it’s a .cap file. I’ve watched a lot of YouTube videos, and most of them mention using a .fd file. I extracted the CRISIS file using 7-Zip, but I couldn’t find any .fd file. I also ran the .exe file, which created a WAXD35C.txt file in the temp folder. I tried renaming that file to .fd and checked it in the CH341 programming software—it looks like a BIOS binary, but I’m not sure if it’s useful or not.

I just ordered a CH341 programmer and want to try writing the BIOS using it. Can I go ahead with this file? I can’t get expert help here in Nigeria, and this model is only available in India. I’m really stuck, so I would appreciate any help you can provide.

You’re not? Then you’re familiar with this operations right and it becomes more easy.

CAPsule bios update files are implemented by the OEM with signature/security/Header ID, for update operations.

.fd files are common used by H2OInsyde bios vendor
.wph are common used by Phoenix Technologies bios vendor
Acer use both of them in their implemented system bios/models
Modern bios/Crisis methods can use all 3 extensions, including CAP.

How can you think that this file (560k) is a bios image when you comparing it, to the TN1RV(BLK)209_Acer.rom (16.384Kb)in the linked package? So draw your conclusions…

The best candidate file is the TN1RV(BLK)209_Acer.rom (16.384Kb) inside the ROM folder.

Before any erase/write operation to the SPI IC(s), you should save backups/readigns of them, as they are now. They should contains specific system data, UUID, SN, MAC, MS OA3 etc…
