There is a known, albeit unofficial, master code generator for older AMI BIOS versions (pre-2021). To use it:
If you can still log into the local Windows environment, you can force the hardware to boot from an external device using internal OS controls:
If default passwords fail, resolving a locked BIOS on the Unowhy Y13 requires moving into technical hardware or software troubleshooting. Because the Y13 uses modern flash storage architectures, traditional methods do not always yield results. 1. The CMOS Battery Drain (Limited Success)
For safety, locate the connector linking the large internal battery to the motherboard and carefully unplug it. Unowhy Y13 Bios Password
Do this twice and compare the MD5 hashes to ensure a good read.
If you own the device legally (you bought it second hand or your school gave it to you), do not resort to soldering.
If you are unable to obtain the password through official channels, there are technical methods often used by professionals to bypass the restriction. There is a known, albeit unofficial, master code
The Unowhy Y13 stores its BIOS password hash on an SPI EEPROM chip, typically from GigaDevice. Unlike older laptops where removing the CMOS battery might clear the password, the Unowhy Y13 implements more persistent security measures. As noted in technical discussions, the password hash is stored on the EEPROM SPI, meaning that simply removing the CMOS battery will not reset the password. This design choice makes physical removal or reprogramming of the EEPROM one of the only effective methods for password removal on newer models. Furthermore, the password stored in the firmware is hashed, meaning it cannot be reversed to obtain the original plain‑text password. As one forum participant explained, “avec le firmware il est impossible de retrouver le mot de passe en clair, il doit être haché donc unidirectionnel” (with the firmware it is impossible to retrieve the password in plain text, it must be hashed, therefore one‑way).
A more permanent solution involves using a CH341A programmer to manually rewrite the BIOS chip's firmware with an unlocked version.
To use these passwords or settings, you must first access the BIOS utility: the laptop. If you own the device legally (you bought
These passwords are primarily effective on older Unowhy Y13 units, particularly those manufactured before 2022. On newer models, these default passwords may no longer work, and more advanced bypass techniques are required. As one forum member noted, “si votre version de BIOS est postérieure à 2021, vous n’avez pas de solution (a moins d’obtenir le MDP par d’autres moyens)” (if your BIOS version is later than 2021, you have no solution unless you obtain the password through other means).
in the available internal slot, which sometimes allows for a clean Windows installation. Summary of Performance & Build : Typically features an Intel Celeron N4100/N4120 Pentium N6000 , 4GB to 8GB of RAM, and 64GB to 128GB of storage.
Do you see an on screen after entering a wrong password? What operating system is currently running on the laptop? Do you own a CH341A programmer tool ?
The BIOS settings menu (usually accessed via or Delete ) is separate from the Quick Boot Menu. Turn off the laptop completely.
