    In BIOS (Acer emachines e730 specific one) I found that it asks for password as I knew it I decided to remove it. There was option to change password so I did that, but instead of filling new password I left empty fields... Now it asks for password and if I don't enter nothing it's not right...

    Old password does not work too. How can I overcome this situation?

    1: There are some backdoor passwords which the manufacturing company had set that will be accepted by the BIOS. You will just need to know the make of your BIOS. Try out the passwords from these lists.

    List of Award BIOS backdoor passwords:BIOSTAR, AWARD_SW, AWARD SW, AWARD PW, CONDO, LKWPETER, J262, 01322222

    List of AMI BIOS backdoor passwords: AMI, AAAMMMIII, BIOS, PASSWORD, A.M.I., CONDO

    List of PHOENIX BIOS backdoor passwords: phoenix, PHOENIX, CMOS, BIOS

    2: To open your laptop please follow these videos dedicated to CMSO clearing or this video to disassemble your model http://www.youtube.com/watch?feature=player_embedded&v=ghSf6ALBUV4

    3:Try to locate the CMOS jumper on board. Set the jumper from pin 1-2 to 2-3 and return it back to 1-2.. This will restart your PC to default settings and erase the password. If you find battery rather than jumpers, try to disconnect it for 2-3 seconds. In some case it is required to give a power cycle to machine without jumper/battery.

    You will need to remove the CMOS battery and put it back in. This will have the effect of clearing the BIOS' "memory" and will reset the password. (I'm pretty sure this also resets the BIOS clock. You can set that in the BIOS settings).

    I want to change my BIOS setting but when I press F2 it asks for a password and I've forgotten it.

    However, if I press enter it just enters the BIOS but most options are greyed out.

    Is there any way to reset the BIOS password?

    My BIOS is Intel BX97520J and I can start the system which has Windows Server 2008 installed.

    See pages 12-13 of the user manual for your D975XBX2 motherboard. The battery is listed as item V in Table 2 on page 12, and the CMOS reset jumper is listed as item S. The diagram on page 12 should help you locate these on your motherboard.

    Pages 52-53 specifically give instructions on clearing your password. As you may have already noticed, the procedure for clearing your motherboard's password is different from most consumer-grade motherboards. Here is the summary, but it would be helpful for you to see the diagrams in the user manual:

    Clearing Passwords

    This procedure assumes that the board is installed in the computer and the configuration jumper block is set to normal mode.

    1. Observe the precautions in "Before You Begin" on page 25.
    2. Turn off all peripheral devices connected to the computer. Turn off the computer. Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).
    3. Remove the computer cover.
    4. Find the configuration jumper block (see Figure 30).
    5. Place the jumper on pins 2-3.
    6. Replace the cover, plug in the computer, turn on the computer, and allow it to boot.
    7. The computer starts the Setup program. Setup displays the Maintenance menu.
    8. Use the arrow keys to select Clear Passwords. Press and Setup displays pop-up screen requesting that you confirm clearing the password. Select Yes and press . Setup displays the maintenance menu again.
    9. Press to save the current values and exit Setup.
    10. Turn off the computer. Disconnect the computer’s power cord from the AC powe source.
    11. Remove the computer cover.
    12. To restore normal operation, place the jumper on pins 1-2.
    13. Replace the cover, plug in the computer, and turn it on.

    Have fun! :)

    There will be a BIOS reset jumper or PWD reser jumper on your motherboard, consult the vendor if you can't find it. This also probably belongs on SU.

    According to your edits that is a desktop motherboard, and it certainly does have a battery on it. It is located between the southbridge heatsink and the 90-degree IDE header. The BIOS reset jumper should be in that location as well. Intel has the manual available on their website too.

    Once again though, this belongs on superuser.com

    does the motherboard have a battery on it that can be removed? try that!

    That used to work back in the day. Remove the motherboard battery, wait a few days to make sure anything storing a charge dis-charges & put the battery back on. The password is gone & the time needs to be reset.
