T23 passwords

Message

Received T23
Told it had HDD password
However, I cannot get into BIOS or BOOT from CD w/o password icon coming up.

There are 3 types of passwords (Supervisor, Power ON, HDD)

Is the following correct?
(1)If the supervisor password is set, then I should be able to boot from CD, HD but not enter bios
(2) if power on password is set, then I should be able to reset it by removing battery and backup battery and letting it post, and then replacing batteries.
(3) HDD password is specific for particular hard drive only

OK ... so I tried to reset the POP, and now I get the message about the time needing to be reset (makes sense), but then the password icon comes right back -- am I doing something wrong?

I think you have cleared the power on password since you are seeing the date change error. Now it is asking for the HDD password, since you do you know this, basically the HDD is trash. You need to get a new HDD to replace it with. Remove the bottom plate and the 4 screws and use it on the replacement.

You can verify that it is the HDD by removing the HDD and booting up with a CD.

To use a new HDD, you will need to get a copy of the operating system or get a set of recovery disks.

The HDD password is saved on the HDD, not in the CMOS area.

So to change the password, you need to know the old one.

Maybe there are tools to 'crack' the password somehow, or the HHD manufracturers set master passwords which you may find somewhere on the net.

But most problaby there's no way around buying a new HDD.

There may be tools to crack passwords on the net, but that's as far as the discussions go here on TP.com. No hacking, cracking of passwords is discussed.

Depends. More on this in a second...

Mostly correct. You need to remove the CMOS (backup) battery for a few seconds, replace it and the main battery, then power up.

clickpoint wrote:(3) HDD password is specific for particular hard drive only

Correct. As pointed out before, the HDD password is stored on the drive.

Depends. Are the icons you are seeing a padlock and a cylinder or a padlock and a square? If you are encountering a HD password, then you will see a cylinder next to the padlock. If either the POP or SVP has been set, you will see a small square icon which is supposed to represent a computer.

If a supervisor password has been set in the system, you will ONLY see that prompt IF you are attempting to access/modify the BIOS settings. This can happen if you press F1 during power up (obviously) but it can also happen if you remove the backup battery. The reason is that the date and time are lost when you do that and the system will ask you to set it the next time it's powered up, which requires access to the BIOS.

By the rules of the forum we cannot discuss any methods or techniques to assist in removing either the SVP or HD passwords.

I understand, I am trying to understand how they work and am only requesting claification of info that is in the HMM. Would that be acceptable?

When I get a chance, I will have to check if its a cylinder or square.
How long would I need to leave the batterys out to reset?

No problem. Only about 5 to 10 seconds should be needed before the power on password is removed. If you have already removed the backup battery for this amount of time, then it should be gone. If you see the square/lock then that's the supervisor password being requested. This is most likely what you are seeing since you said that you got a date/time error when after you pulled the backup battery. I think if there was a HD password and NO SVP, then you would be allowed into the BIOS to reset the date and time, before the HD password would kick in.

This occurred to me earlier... if you were starting the system with the hard drive installed in the system but wanted to boot off of the CDROM, the BIOS boot order may have been set to look at the hard drive first (unless you were pressing the F12 key at boot). If there's a HD password, then this could be the reason that it would prompt you (and not attempt to boot the CD).

edit: I'll have to eat those words... Just tried this on my T23 with both SVP and HD passwords. I re-booted and pressed the F12 key. The HD password prompt came up. I entered the password and then the Boot Menu appeared. So it seems like the BIOS checks for all bootable devices first and then allows you to pick from them.

Finally got to play a little (baby and mom came home from hospital yesterday, so tied up elsewhere

) ...........
I pulled HD from another t23, and added cdrom......
The I get a splash screen, error about time, and then password lock icon (SQUARE) ---- so I assume it's either the PSV or POP....

So the POP should be reset, by removing the battery. (which I did)
So I assume this is the PSV password that it is asking me for....
but why shouldn't I be able to boot from either the HD or CDROM if its not the POP?

Because you removed the CMOS battery, you did remove any POP password, but you also reset the date and time, which needs to be set for the boot cycle to continue. Apparently you have a SPV password set, so without knowing that, you cannot change the date or time. It may be possible to continue to boot, but likely you are going to be stuck at this point until you can clear the SPV password.

Sounds to me like a Power on Password, and battery removal will not reset it in my experience. There are "ways" to retrieve it, but as carefully pointed out, they are not and will not be discussed. I was forwarned a while back in asking for password locked HDD's for "testing".

I wish you good luck.
