    I am having the same problem with a Inspiron 9300 and on these newer laptops removing the cell battery is not resetting the BIOS.
    I have found out that on my system I have to flash the eeprom-chip and to do that I need to take apart the computer and reassemble it to the extent that I can get to the chip on the back-side of the MB at the same time.
    Can anyone give me a link to a guide or otherwise....need pictures of eeprom

All you need to do is to make your way in through the keyboard area where a button cell is located... removing that will reset the bios of your laptop to manufacturers default, no passwords you also have to set everything right the date and time settings, and a new password.

At the sides of the keyboard are simple locks... use a flat screw driver... just be careful in working with it so as not to cause scratches or damage to keys.

I want to remove a ASUS Eeepc 4g bios password which i forgot please guide me thanks. can calculate a bios master password for your ASUS notebook for $20 and they guarantee it to work. The bios master password will clear the currently set bios password, giving you full access to bios setup. I repair laptops and I use them when I get a laptop with an unknown bios password or unknown hard drive password and they have always worked for me.

B110 Desktop...the bios password has me locked out. How can I reset to the factory bios password. How do I set a new bios password when I don't know the current one????


You have to open up your laptop notebook by removing all the screws at the back of your computer but make sure you remove the battery and then remove the CMOS battery at the motherboard and return again to reset the BIOS setting and will remove the password.

I hope it helps you.

To reset the BIOS password read the information from this link.

If you don't want to open the case, the easiest method would be using software from Hiren's Boot CD to reset the password or clear the CMOS all together.

HP laptop Pavilion DV 4000 Password

Now, tell me how one sets a bios password, then just forgets it?
If you can prove ownership on a laptop as new as a DV4000, there are plenty of posts out there describing the proceedure for recovering the system. Occasionally even HP will helpout legitimate owners in situations such as this.
I'm sorry, but this isn't the forum for this particular problem.
Good luck
