Need to bypass/clear the Compaq Presario 1200 bios password

My friend just gave me a Compaq Presario 1200 notebook and when I tried to boot it, it asked me for the bios password. No matter what I do, so I can't neither boot in windows nor get into the bios. My friend doesn't know it too. What should I do to bypass or clear it, please?

    Well, this model series is old. The battery (if it has, i can't seem to find it) is a goner (doesn't charge, always empty) and the case's screws are TORX type. I also tried phoenix bios backdoor passwords. They didn't help :(

  • grech_kevin Jul 31, 2009

    Sorry but i can't open the case. It has torx screws :S

  • grech_kevin Aug 01, 2009

    Hmm, thanks for the help guys. I managed to reset the password :D

Try removing the main battery, then open the case. Under the keyboard and close to the CMOS chip, you may find a reset buttom or jumper. Alternativelly, you may remove its small round-shape battery for half an hour or so. This would return CMOS features to default. Fix power supply again and restart, normally the BIOS should stop asking for a password

    The cmos battery is under the keyboard on the motherboard.There is also a jumper that will have the same effect

    You can buy a set of torx tools for a couple of dollars.

I have recently fixed my Compaq presario 1215 laptop by replacing the CMOS battery (CR1220 in my case). Before that, it kept asking me a password on boot after showing many BIOS related errors. After three password attempts it gave me the 65535 hash code. Removing the battery for 5min did not help. Putting a new battery did.
For my laptop I have to remove the 3 bottom screws on the front. Then open the laptop and carefully pry out the speaker-touchpad cover (it has a cable, so do not pull to much). Then you can flip over the keyboard (it also has a flat cable, do not pull too much). At this point I place masking tape to hold them in place.
Where the keyboard was, you can see a metal plate with 3 screws. Remove the screws and pry out the plate (it is a bit tough, for it has a sort sticky surface that makes contact with processor.
Now you see the internals. Towards the rear there is a small print board that has two connectors. A small one on the left that can stay in place. A big one that connects it to the main print board. Use a small plastic stick or equivalent to pry it up on the right side. Then flip it to the side.
The CMOS battery is completely at the rear, under the attachment of the screen. Use flashlight to locate it. Pry it out (it has a plastic U-cover that will come off as well).
To place the new battery, I placed two small masking tape portions on its side so that my fine tweezers can have a good grip to place it in its lodging. Then use small plastic stick to push it in place. The same with the plastic U-cover. Put everything back. If you have accidentlally removed the 2 flat cables from keyboard and touchpad, then push them back in before placing back the metal plate.
Presto, your 20 year old laptop should work again and let you go into BIOS settings without password.

How do i unlock my laptop without knowing my password


If it is a bios password before windows loads, you need to remove the cmos battery on the motherboard for a few minutes and then it should have cleared.
A windows password is much harder.
You will find lots of help online if you type into google "windows password bypass"
Windows xp is alot easier than vista or 7 tho

Password


Some BIOS manufacturers implement a backdoor password.
The backdoor password is a BIOS password that works,
no matter what the user sets the BIOS password to.
These passwords are typically used for testing and maintenance.
Manufacturers typically change the backdoor BIOS passwords from time to time.

Compaq presario 2500 trying to clear power on password


If you have forgotten your password and it is stored in the BIOS, then you can reset the BIOS to the factory default state by removing the BIOS battery, wait for over 1/2 hour for the BIOS to discharge and wipe its contents, then reconnect the battery. You will need to reconfigure the BIOS before Windows opens.

I do not know this model, but if the password is stored in an EEPROM chip then it is near impossble to reset it without knowing the actual password. It would be difficult to remove, if you know a friendly hacker with a piece of hardware that can read the contents of the EEPROM chip and then identify the password, so he can tell you what it is.
Best of luck.

If there is a cancel button with the password prompt, hit cancel without entering a password, or hit enter without entering a password. Sometimes if there was a password, even though there may not be a password currently, the system will still prompt for one, if you enter a password then it locks. The other things you can try is: At start up, hit the F8 key and go into safe mode, log on under the administrator and clear any user passwords in the user accounts. You can also try, at start up, entering the bios or utility set up and check to see if the bios password setting is enabled, then disable it. Rarely, but on occasion, a hard drive will fail and cause the password prompt. If this is the case, then the hard drive will need to be replaced.

Frogot password


It would help if you will clear the BIOS or the CMOS of the laptop. It can be cleared by pulling out the cmos battery of the laptop for a long period of time or by locating the jumper/dipswitch on the motherboard that would clear the BIOS. You may go to these links on ways on how to clear an unknown BIOS password.
