Password problem

durkinjt · Nov 3, 2025

When I boot my computer it asks for password, nothing comes up when any password is installed, after the 3rd try I get a logo that contains System Disable 2c96fc790a57e27 , then under Service Tag 6q4vw1

What is the Make and Model # of your computer?

Is this a Windows Password to logon to the computer?
Or is it a Bios Password that will ask you for a password before it will load Windows lock screen.
When did this behavior start? Did it every not ask for a password?

Take a picture with your Smart Phone and attach the picture in your next post.

Hope I'm wrong but that sounds to me like that is a system disabled halt code. Copilot's answer.

A "System Disabled" halt code typically appears after multiple failed BIOS or power-on password attempts and locks access to the system.

Here’s a breakdown of what it means and how to address it:

What is a "System Disabled" Halt Code?

Triggered by incorrect BIOS or power-on password attempts: After three failed tries, many systems (especially HP and Dell) display a "System Disabled" message followed by a unique code.
Security feature: It’s designed to prevent unauthorized access to the system firmware or boot process.
Not a Windows password issue: This occurs before Windows loads, at the firmware level.

How to Fix or Bypass It

1.

HP systems: The code may start with a letter (e.g., A[B3290309]). These can sometimes be reset using online BIOS unlock tools or by contacting HP support.
Dell systems: You may see messages like “System BIOS has halted.” Dell support may offer master password recovery or require clearing NVRAM via jumpers.

2.

Some websites offer BIOS unlock services based on the code displayed. These may work for older HP/Dell models but are unofficial and carry risks.
Example: ToxicNerd provides a guide for HP systems with codes starting with “A”.

3.

HP: May require proof of ownership and could suggest motherboard replacement (often costly).
Dell: May help reset the password remotely or guide you through jumper-based recovery.

you used to be able to bypass/generate them and/or purchase one generated for a specific model/service tag but those days are long since gone

If this is indeed what it is, IMO you will have to contact the OEM. I stay away from using bios passwords myself, just not worth the gamble, so have not ever had to deal with it.

The OP's specs just say 'PC/Desktop'. Desktops often have a password reset jumper on the motherboard. Consult the manual to find out if this is the case here, and how to reset it. Laptops generally don't have a reset jumper these days.

durkinjt has asked the same question on Tom's Hardware: Question - Password Problem
..and back in Feb. 2024 here on Bleeping Computer: Delete password - Windows 11

Good find @Bree Seems this user hopes that the answer to his problem will change. He posted that one back in 2024.
Things might not be on the up and up about this device.

Since this is a used computer, the best and safest thing to do is either reset or clean install Windows 10 so you can set it up fresh.

This is bios password problem. Not windows password. So he cant even go to boot menu or boot from install media.

Your service tag seems to be missing one digit or letter. Are you sure that service tag is 6q4vw1? Could be 6q4vvv1 which is Dell OptiPlex 790 Desktop PC. If thats the case then CLR CMOS JUMPER or removing bios battery should do the trick. just make sure that power cord is disconnected, and pres power button when you remove thw battery. Check service tag again and post here.
