Resetting a Surface Pro 4 BIOS Password For the Microsoft Surface Pro 4, a BIOS (UEFI) password is a high-level security feature. Unlike standard desktop PCs, you cannot reset it by simply removing a battery or moving a jumper. Official Microsoft Stance
Microsoft officially states that it cannot retrieve or reset a forgotten UEFI password for the Surface Pro 4. There is no software tool or "master password" provided by the manufacturer for this purpose. If you lose this password and need to change BIOS-level settings (like boot order), Microsoft typically recommends a full hardware replacement. Technical Workarounds (Advanced Users Only)
Because there is no standard software reset, the only known "high quality" way to remove the password involves advanced hardware modification. This should only be attempted by professional technicians as it carries a high risk of permanently damaging the device. Reflashing the BIOS Chip:
The Process: This requires opening the device—which is difficult as the screen is glued down—and desoldering the BIOS chip (model 1724) from the motherboard.
Programming: The chip is placed on an external programmer, the firmware is reflashed to a "clean" version without a password, and the chip is soldered back onto the board. Known Risks: surface pro 4 bios password reset high quality
Loss of Touch Functionality: Reflashing with an incorrect or non-original BIOS region can lead to the touchscreen failing. In these cases, the BIOS may show a touch firmware version of "000000".

Resetting a forgotten UEFI (BIOS) password on a Surface Pro 4 is significantly more difficult than on a standard laptop. Microsoft does not provide a software-based tool for users to reset this password, and typical methods like removing the CMOS battery generally do not work because the password is stored in non-volatile EEPROM memory. 1. Hardware Modification (Expert Level)
Because Microsoft cannot retrieve or reset the password, the only definitive "high quality" way to remove it is by physically reflashing the BIOS chip. This is a complex task that should only be performed by a professional technician:
Access the BIOS Chip: The Surface Pro 4 must be disassembled, which is high-risk as the screen is glued and prone to cracking.
Desolder the Chip: The BIOS chip (on model 1724) is often desoldered because it is too close to a heat shield for a standard clip.
Reflash Firmware: The chip is placed on a programmer to overwrite the original BIOS region with a "clean" one, effectively removing the password.
Reassembly: The chip is soldered back onto the motherboard and the device is re-glued. 2. Microsoft Configuration Tool (Enterprise Only)
If your device was part of an organization, it might be managed via the Microsoft Surface Enterprise Management Mode (SEMM).

For high-quality technical recovery, you have three primary paths: the official hardware service route, a complex chip-level hardware bypass, or a specific software configuration workaround if you still have Windows access. 1. Hardware Bypass (Chip-Level)
This is the only definitive way to clear the password from the motherboard physically. It requires advanced microsoldering skills and specialized tools. The Process: The UEFI password on a Surface Pro 4 is stored in a non-volatile memory chip on the motherboard
. To reset it, a technician must disassemble the device—which often involves removing the glued-on screen —and desolder the BIOS chip. Reflashing: Once removed, the chip is placed on a programmer (like the RT809F Serial ISP Programmer
) to read the current data, "clean" or reflash the BIOS region, and then solder it back onto the board.
This process is extremely risky; it can break the screen during disassembly or corrupt the touch screen firmware, rendering touch input unusable. 2. Software Workaround (SEMM Method)
If you still have access to the Windows operating system on the device, you may be able to clear the password using the Microsoft Surface Enterprise Management Mode (SEMM) The Concept: Surface Pro 4 BIOS Password Reset: A High-Quality
SEMM allows organizations to manage UEFI settings via software packages. The Steps: Download the Surface UEFI Configurator Microsoft Support
