BIOS Password Issue for HP

Hello,
my PC is based on an HP D530 (CMT) motherboard with a Compaq 768B2 BIOS. The problem is in the title: I have a password in the BIOS that I know, but when prompted for the password, nothing is typed. I can only press enter to validate, and after 3 wrong attempts I can enter the BIOS, but I can't change any settings (desktop PC and BIOS version 2.5). I tried to reflash the BIOS with a tool provided by HP but with no result, and I attempted a BIOS reset with the jumper and even removed the CMOS; the BIOS resets but the problem persists T_T

Thanks for any possible help!!
Configuration: Windows XP Internet Explorer 7.0

BIOS PASSWORD

Nothing is more embarrassing than forgetting your password to access the BIOS. No way to make the desired changes. Thanks to Louis, a member

The BIOS is a program embedded in a flash memory on your motherboard.
It is the only means of communication between the hardware and the operating system
installed on your computer. If it is the user password, you can't even boot.
However, there are a few ways to bypass the issue and erase the password. The existence of these methods shows that having a password is essentially just superficial security. Access to the data is indeed possible for anyone with a little knowledge. Only encryption of data storage provides true security.
Let’s move on to the troubleshooting processes in case of password loss. Here are some possibilities.
You can read the password using a specific program from your motherboard manufacturer.
Some old motherboards (rare today) with AWARD BIOS accept the following universal passwords: LKWPETER or AWARD_SW (AWARD?SW on English keyboards).
Accessing the BIOS:
As soon as the computer starts, press a predefined key depending on the type
of the BIOS of your computer or the manufacturer.
There may be a warning message indicating this ( "Press Del to enter Setup").
The Award BIOS can be accessed by the Delete key.
The Phoenix BIOS by the F2 function key.
At Acer (among others!), the prize for originality goes to: pressing Ctrl Alt Esc simultaneously.
All Compaq BIOS activate with the F10 function key (when the cursor is on
the right side of the screen).
Some IBM brand computers’ BIOS can be accessed by the F1 function key.
When in doubt, try all possible combinations

Solution 1
In the absence of specific programs, many motherboards offer a DIP switch or jumper near the battery (often located next to the keyboard connector or the battery) that allows erasing the CMOS RAM. You then need to switch it to position 2-3 if it is set to 1-2 or vice versa. However, you should refer to your motherboard's documentation to see what type of switch or jumper exists and where exactly it is located.
The process is as follows (After turning off and unplugging the power supply from the PC): open (or close) the jumper. Turn on the computer and then turn it off again: then replace the jumper in its original position, and turn the computer back on.
Before putting the battery back in place, check by turning on the PC that the password has indeed been erased. If not, don’t hesitate to repeat the operation while extending the waiting time.
Remember that you are not only erasing the password, but also all the settings, including those concerning the hard drive(s), which will need to be adjusted again.
NOTE: For most BIOS, when the computer no longer restarts, simply hold down the "insert" key while you restart the PC. This will reset the BIOS settings or, more precisely, restore the "factory" settings. They may not be the best for your configuration, but at least they should work.
In the case of old motherboards, the battery can often be difficult to remove. It is frequently integrated into the real-time clock module or soldered directly onto the motherboard.
In this case, the only solution is to create a short circuit on the battery for a few seconds (but it can take up to twenty minutes to allow the memories to discharge), for example, by connecting the two terminals (+ and -) with a paperclip. The power supply to the CMOS module is then interrupted and its content erased. REMINDER: the PC must be off, with the power disconnected.
Don’t panic! Upon the next restart, the BIOS will indicate that something is not right in the CMOS and will revert to the default values. Again, all your possible settings will naturally need to be redone, and you will have to re-declare your disks if necessary. (In newer BIOS, it often suffices to reset the "TYPE" and "MODE" values to "AUTO" in the "STANDARD CMOS SETUP" section) - set the date and time and declare drive A as 1.44M, 3.5 In. Also, check that your processor voltage matches that indicated by the manufacturer (See in the BIOS menu "CPU SOFT MENU"). You can also launch the automatic detection of your HDDs "IDE HARD DISK DETECTION" in the main BIOS menu, or CMOS SETUP UTILITY (This may slightly change depending on the type of BIOS)…

Solution 2
- Remove the password in the BIOS using the DOS command: Debug.
Restart the computer in MS-DOS mode.
If your computer has an AMI or Award BIOS, the commands are as follows (and nothing else):
debug (then press the "enter" key on the keyboard).
O 70 17 (then press the "enter" key on the keyboard).
O 71 17 (then press the "enter" key on the keyboard).
Q (then press the "enter" key on the keyboard – The letter Q allows you to exit the debug procedure).

Warning: It is the letter O in uppercase and not the number 0. The uppercase is very important, do not forget it.
Leave a space between each term: O (space) 70 (space) 17
Restart your PC and enter the BIOS. The password should be gone. Then redo your settings as mentioned above.
For the Phoenix BIOS, do as indicated below:

debug (then press the "enter" key on the keyboard).
O 70 FF (then press the "enter" key on the keyboard).
O 71 17 (then press the "enter" key on the keyboard).
Q (then press the "enter" key on the keyboard

With the default settings restored in your BIOS, the password issue should now be just a bad memory.

Software Solution SoSWindows <http://nanar10.free.fr/> provides you with 3 small programs for download depending on the brand of your BIOS. Note: the BIOS will then revert to its initial settings, and you will also need to adjust some aforementioned settings. There are BIOS AWARD CRACKER - AMI DECOD - etc…
