Question about Fujitsu Siemens AMILO Pro V2000 Notebook

1 Answer

BIOS PASSWORD I need to remove bios main password, only way it seems is to shortcircuit pins, or reading with paraller port, but i prefer short circuiting. Maybe you know what pins it should be in this laptop. Or where I can get tech scheme for it? On Fujitsu website I can't find it, and so I even can't find bios chip.

The pins you are looking for are usually the same ones they are jumper pins JP1 and JP2 the pins usually have a caption near it CLS CMOS . BUT this is a bios issue , the information will most likely not be reset by doing a CMOS reset i know for this issue with the IBM thinkpads you have to have the chipset replaced , and im sure it will probably be the same for a F-S. you can try the other approach but im not sure what will result from it

"Reset you're cmos/bios jumper to


HI,
No need to worry. There are many known ways to reset / remove / bypass the password:
  • By removing the CMOS battery
  • By using the motherboard jumper
  • By using MS DOS command
  • By using software
  • By using Backdoor BIOS password
Now I'll try to explain each method one by one:
A. By Removing the CMOS Battery:
xrojer_2.jpg
Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.

B. By Using the Motherboard Jumper:
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

C. By Using MS DOS Command:
This method works only if you have access to the system when its turned on because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands one bye one:
debug
o 70 2E
o 71 FF
quit
NOTE: The first character in the above commands is "O" and not the number 0.
After providing the above commands, restart your system and it should reset the CMOS Settings along with the BIOS password.
If you are curious to know how it works? then let me explain the above commands:
In this method we are using the Debug tool of MS DOS. The "O" character present at first in these commands, outputs the values to IO ports. The number 70 and 71 are port numbers which are used to access CMOS memory. By providing FF value we are telling CMOS that there is an invalid checksum and it resets the CMOS settings as well as BIOS password.

Don't know BIOS password


Here's how to reset password

Resetting a Toshiba BIOS Password KeyDisk will reset the BIOS password on Toshiba laptops.
Older Toshiba laptops can be convinced to boot without their power-on BIOS password by attaching a dongle to the parallel port which crosses a number of the pins. The pin out is:
Pins 1-5-10 2-11 3-17 4-12 6-16 7-13 8-14 9-15 Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.

If yous has a BIOS password (password = _) when you turn the laptop on, then the only fix is to buy a parallel port password removal key (they go for as low as $10 on eBay), or you can make your own (schematics are available for free on the Internet), then plug the key into the laptop's parallel port, turn it on, and the CMOS password will be removed. There is no shorting of pins or removal of CMOS battery for this model.

How to Break BIOS Setup Password


there is no way to break that password..the only way to remove it is to reset the bios by short the clear bios pins(jumpers)..or remove the bios battery ..this will erase any settings and when you put the battery back will be on optimal factory defaults..(same if you locate the jumpers for clr Bios) but ..for that you have to open the laptop ...its easier for desktops..but for this will be a little much ..but is the only way ...so ..in short be careful and you have to get to the motherboard and remove the battery ...if you do not have an acces point to the jumpers..

How i can remove Bios password from Toshiba


There is NO way that it can be fixed OTHER than returning it to the manufacturers or agent. They have proprietory Software Challenge Codes and this will do the job. However they cahrge for this usually around $125. Also one must provide proof of purchace and ownership. You can also find places online too, however they also cost.

Steps for Clearing BIOS Password Check

If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:
• Power Off a system, and remove HDD, AC and Battery from the machine.
• Open the back cover of the machine, and find out the HW Gap on M/B as picture.
• Use an electric conductivity tool to short the two points of the HW Gap.
• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.
• Restart system. Press F2 key to enter BIOS Setup menu.
• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.
NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

Have ibm2668 thinkpad has old pass code can't get in it.


I think this is bios pass? There are two ways - shortcircuiting bios pins or parallel method. Anyway you must disasemble your computer. Try to remove bios battery first (its under keyboard) for two hours. It's a very small chance this will help. When removing battery does nothing, you must search on google which bios pins to shortcircuit in your model. Problem is if you don't have manual/tech scheme for your machine. Try to download it from manufacturer website. You can use a parallel method, but it is harder. Shortcircuiting really works, one guy on fixya was fine with bios pass. Wish to help you more, but I cant, I have the same problem with Fujitsu Siemens, and so on, no solutions, no tech scheme :(
Finally you can use a universal and manufacturer password, search for these two, For universal, you must check what kind and version of bios you have. It usually shows when you just starting computer.

I need to clear my Bios Password for My IBM Thinkpad R52


OK, I posted this the other day, so for the benefit of those who missed it. "None" of these techniques will work on the R52, as it has a different chip. The above well intentioned solutions mentioned above will work with older models but not this machine as the bios chip has been changed. FYI
