T61 power-on password corrupt

Hi folks,
I have a T61 in the office and I needed to restore it to defaults for use by another user. The computer had a power-on and hard disk password that was the same, set by the previous user. I went into the BIOS with this password and was able to clear the hard disk password. However when I tried to clear the power-on password it said it could not while the supervisor password was set. This was strange to me since all the passwords were the same and it never requested a supervisor password before.
I then proceeded to try to clear the power-on password with the instructions in the ThinkPad T61,
R61, and R61i (14.1-inch widescreen) Hardware Maintenance Manual. This involved disconnecting the main and backup batteries. After this it started up showing two messages, one that the date and time was not set and the second that the BIOS settings were in error and that it was using the default values. I then still got the power-on password prompt however. This time none of the previous passwords I set works! I'm locked out of the machine.
Can anyone help?
Thanks

T61 Power On Password ... can`t reset it

I used to have 2 passwords, one on the hard drive and one for the Power On. But I was never asked about them, every time using the fingerprint. Yesteday I have just re-installed the Windows. I shutted down the laptop and when I need it opened I found that I need to put my passwords. I couldn`t remember the Power On Password.
I searched on the net and found this link
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-59377
Turn off the computer.
Remove the battery pack.
Remove the backup battery.
Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed.
Reinstall the backup battery and the battery pack.
I did exactly what they say for reseting the Power On Password. Or maybe I might missunderstand the POST meaning. I thought this means the Icon where I am asked about the Power On Password. Am I right? If not, what does "POST ends" means? Because I am sure that this message for the password won`t dissapear.
Please let me know what should I do in this case.

I'm really sorry, but we are dealing with the supervisor password, the most secure password on a ThinkPad. The pictures on the site you linked to are unfortunately a little outdated.
You will need to remember this password and delete it in BIOS. The forum rules forbid discussion on this subject. Discussion of the POP, (Power On Password), is permitted as this is openly published for all to see. e.g. the site you linked to.
You may be able to get some assistance from support if you call them.
Unfortunately, in accordance with the rules, I am locking this thread.
I wish you luck and hope you can resolve this.
Regards

T61 power on password

I tried to remove my poweron password but it had a supervisor password that I did not know so I removed the backup battery and upon putting it back, the power on password button still comes on and when I put my password it does not recognize the old password anymore
please can somebody help me

eafambu, welcome to the forum,
removing the backup battery is the correct proceedure to remove a power on password, as stated in the Hardware Maintainance Manuals and the Lost or forgotten password - ThinkPad General site, you will also see that it is not possible to delete the supervisor passord without knowing it.
You options are to remember the password, find it out if you purchased the system from a previous owner or contact support who will more than likely suggest you replace the mainboard.
It states in the forum rules;
No posts shall include instructions or directions intended to subvert security measures, including passwords, locking mechanisms, fingerprint scans, etc, nor shall any posts provide descriptions to the location of, nor direct links to content related to these topics.
Sorry, thread locked.

Does the power-on password fully protect user data?

Hi,
I am a T61 user.
First question
Does the power-on password fully protect user data, or could someone just boot from the optical drive or another source?
Second question
If I were to use full disc encryption, could I easily unecrypt it in the future?
Thanks in advance!

As mostly with everything in life, there are pros and cons related to all sort of data protection schemes. At least in therory, everything that can be encripted may also be decripted in some way, be it via reverse engineering or some other technique. - But of course some sort of protection is always better than no protection at all, especially if you deal with lets say sensible data.
The power-on password is not a full data protection at all, to get an idea of the different password protection schemes take a look at the following short descriptions here...
--> http://www.tech-faq.com/ibm-thinkpad-bios-password.shtml
...there are some ways to reset a power-on password and informations how to do so can be found on the net. Further it doesn't help much if somebody takes out the whole harddrive of your Thinkpad.
Performing a full HDD encription, via an embedded ATM hardware chip inside the Thinkpad, or even using some OS related encription mechanism would be more secure for sensible data, as long as you don't get hardware or software trouble with those parts, which are responsible for the build-in encription/decription scheme. So it's always also a good idea to also perform additional periodically backups of your sensible data, so if some worst case scenario might appear, that you are still be able to restore your valuable data.
Hope this gives you at least a little idea about the pros and cons of both of these security schemes.

Help Please - X200 will not boot after Bios Upgrade - keeps asking for power on password

Hi there,
I am new to this forum and please let me say a big Thank You for your help in advance.
I am using a lenovo thinkpad x200 running windows vista with service pack 1.
The laptop has always been running fine and has never given me any issues. Unfortunately, all this came to an end yesterday when I ran the system assistant which did a round of updates and it prompted me to reflash my bios.
I did what was instructed and closed all open applications and after the laptop restarted, there was a noise from the harddisk (the sound was basically like what happens if the harddisk suddenly loses power). Then, all i got was a black screen, no harddisk acitvity with only the power cable LED and another LED (with the shape of a N tiled at 20 degrees) on.
I searched the forum and did what was suggested in this entry: http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Blank-screen-after-Bios-Upgrade-on-X200/ta-p/29...
This is what I did so far"
I turned off the power, took out the backup battery and waited for about 30 minutes (repeated this step several times, also removing the harddisk) but to no avail.
I removed the RAM and tried booting and there was that characteristic beeping sound.
I replaced the RAM, redid the CMOS clearing, and now there is the Lenovo startup screen. However, there would be an error code 0271 (no date time) and 0251 (something about default configuration). Then, these disappear and all I am left with is the Bios Power On password prompt. Somehow no matter what I type nothing can be input into the field (and I did not create any password as far as I can remember).
I redid the clearing for the power on password by removing the backup battery as suggested at the bottom of this page http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-59377 but it is no use. Each time I restart, even if I press the blue Think Vantage button or F1 or F11, I still get the same 0271 and 0251 error messages and am left with the power on password prompt.
I am really desperate as I really like my lenovo x200 and there is important data on the laptop. I would appreciate any suggestions on how I can solve this. Its amazing how a simple update can turn into such a disaster. Now i know i should never upgrade or update my Bios (or at least proceed with extreme caution).
Anyone can provide some help to get my laptop workin again?
Thank you very much,
Mark

try reflashing your bios?

Don't know power on password for hp touchsmart 520-1020 windows 7 64 bit

My touchsmart 520-1020 was powered off and when it came back on it was asking for a power on password. Can anyone help me with this? Please? when i enter a random password three times it doesn't give me a code. it shows a key each time i press enter after entering a password and after the third time it has an asterik. and then no more options. the date is shown at the bottom right hand corner.

Hello cmeryers76:
Your password should be the same one you use to log into windows. Why you are seeing a date is be yound me. This seems more like a bad virus or malware. If your sign in password still fails. Unplug the computer while this screen is still being displayed. This is what we call fource restart. Ounce the computer is completely off plug it back in and turn on your computer you should start up in safe mode screen option use arrow keys select safe mode with net working. Close out help and support window. Locate the the recovery manger and Click yes in prompt window if displays then select Microsoft System Restore in next two screens click on next You well eventually end up with dates listed choose a date before this event occurred then click next follow all command promts. Ounce recovery point has been completed run your antivirus software. Then do a PC Tune Up. Go to your control pannel and open up Performance Information and Tools select Adjust power settings on the right hand side. Then select Choose when to off the display. Next window switch all boxes to never. You will never have to worry about this ever again. On top of that the issues you face trying to wake up the computer from sleep mode.
If the same screen displays on start up by a chance then unplug the computer hold down power button for five secounds then plug it back in turn on computer tap f-8 key follow above recovery steps. If this fails to open in safe mode. Then full recovery is only option requires recover discs. Power off the computer turn it on and tap f-10 key and insert disc one of recovery disc follow all command prompts. Ouce fullrecover is completed follow the above dirrections for the display settings above switch all thee settings to never. frrw

Fingerprint instead of power on password not working any more

Hi,
my current configuration is T530i model 2392.
I recently updated BIOS to version 2.52 from 12. Feb. 2013 and of course some other software especially solid state drive firmware Version FWSS28 from 14. Feb 2013.
In BIOS Predesktop Authentication is enabled in addition with harddisk password and power on password.
Now to my problem:
before updating I software I could start with only swiping my finger over fingerprint sensor, without providing any kinde of password for harddisk or power on password. I received information about success & windows 7 (64 bit) was booting.
Now I need to provide power on password all the time, seems that fingerprint or BIOS now has a bug ?!
I did several things like:
disabling every password request in BIOS rebooting...
disabling deleting fingerprints on laptop and rebooting...
unchecked all necessary settings in fingerprint security software like SSO, power-on-password, fingerprint sensor should replace power on / hard disk password..... reboooting...
- then enabled everything again which I unchecked before.... rebooting....
Nothing has worked so far, so there it seems to be a bug in predesktop authentication...
Could you please advice or provide a fix ?

Hi,
here short terms how I fixed it:
- opened fingerprint program & disabled everything which is of concern for authenticating with fingerprint
- deleted fingerprint with that software too
- disabled biometric device with windows tools
- deleted TPM with tpm.msc
- removed everything from BIOS regarding fingerprint, password for booting, hdd, etc
- resetted fingerprint with bios too
- loaded bios setup default (cause it was a BIOS update)
- shut down computer
- startup again and set everything in BIOS which is needed and has been disabled before
- did the same in windows (enabled everything again)
- rebootet.... prayed... computer prompts with "fingerprint matched" ==> first YEAH
- provided boot up password once....
- shutdown again....
- started with enrolling fingerprint only.... no prompt for password any more.... second YEAH
DONE

Power on password for compaq 6910p

How do I find out what the power on password is for a Compaq 6910p
This question was solved.
View Solution.

Hi:
Here is the service manual for the 6910p.
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01566975/c01566975.pdf
You will find the information you need to clear the power on password in chapter 4, page 38.
Wait 30 minutes before re-connecting the CMOS battery, not 5. You may even want to leave it unplugged along with the main battery and start the notebook only with the A/C adapter with BOTH batteries disconnected. But at a minimum you must leave the main battery disconnected, and start only with the A/C adapter attached.
If that procedure does not clear the power on password, your predecessor enabled stringent security in the BIOS, and it will be your chance to get a new notebook for your new position, as the one you currently have will need a new motherboard in order to be of use again.

Power on password error

Refer to the link mentioned below which is he manual for this particular model and check under the heading
"1.2 Resetting the Computer" and follow the steps to clear the password.
http://h20565.www2.hp.com/hpsc/doc/public/display?sp4ts.oid=447371&docId=emr_na-c00622160&docLocale=...
Remove the main battery and the RTC battery. and then power the notebook up with AC power. That is supposed to clear the password.
