The primary function of the PC CMOS Cleaner 2.0 is to reset the CMOS settings to their default values. This can solve a variety of issues related to incorrect or corrupted CMOS data.
The following guide explains how to prepare and use the version to regain access to your system. Phase 1: Preparing the Bootable USB
Once the USB is prepared, follow these steps to use the PC CMOS cleaner: 1. Configure BIOS for USB Booting
In computer maintenance and IT asset recovery, a locked BIOS prevents system modifications or re-imaging. While modern systems store passwords in non-volatile memory (EEPROM/NVRAM) which is difficult to clear via software, older systems (and some specific BIOS vendors) retain settings in CMOS RAM, which can be reset via software interrupts. pc cmos cleaner 20 usb boot verified
This extensive support list means that, for a very large number of desktop PCs, servers, and older laptops, PC CMOS Cleaner can successfully recover or remove the BIOS password, regardless of the motherboard brand.
Stop breaking your fingernails on jumper blocks. Stop losing those tiny plastic caps.

Locked out of your BIOS? Whether you’ve forgotten a supervisor password or inherited a machine with restricted settings, PC CMOS Cleaner 2.0
With the verified USB drive prepared, it is time to interface with the locked computer.
But if the BIOS is physically bricked? If you flashed the wrong update and the system is completely dead (no POST, no beeps)? Phase 1: Preparing the Bootable USB Once the
The most universal method for desktop PCs is a physical CMOS reset:
Insert the prepared CMOS cleaner USB drive into a primary motherboard port (preferably a rear USB 2.0 port rather than a front panel port).
: Works on most motherboards (x86 and x86_64) regardless of the installed OS. Step-by-Step: Creating a Verified USB Boot Drive
This comprehensive guide explains how CMOS wiping works, how to create a verified bootable cleaner drive, and how to safely clear your system settings. Understanding CMOS and BIOS Wiping
If PC CMOS Cleaner does not work on your system — or if you are dealing with a very modern motherboard or a locked laptop — consider these alternative methods.
