Remove the cmos battery and ac power cable. Then press and hold the power button for 5 seconds. Then put the battery back in and your cmos will be reset

Testimonial: "i have changed the battery twice i have held the power button and even tried a coin to short out,, every time i have to restart after an update for example, i get cmos battery is bad/low and i have to set the date and time about 5 different times before it accepts it and starts to boot normally . it seems not to reset and be stuck with low battery although the battery is fine"

    Sry, if the battery is fine then i think your motherboard is either broken or needs a bios update. Do you have the latest bios installed? if not i'd recommend trying that before dumping the laptop. ( u should find the latest bios at the laptop manufacturer's website and instructions on how to update it)

Thanks Steel Breeze!! I did exact as you suggested and it was easy. I used a Dremmal tool to cut a squre holes. You can actaully see part of the battery (CR2032) through one of the existing holes.

SOURCE: How to reset bios password

The FSC 1320D's are truely remarkable... We haev had a default BIOS password for our laptops for a while now, but it has recently started to have been guessed or found out. So of course, they needed to be changed. And suprisingly enough, the FSC 1320D will not allow you to reset the BIOS password through ANY user method so far, and we really have tried everything.
Removing the BIOS battery - This does nothing, at the best of times the system will display an error saying it has been removed but other than that the BIOS password remains.
Updating the BIOS - Most people would suspect that if you update the BIOS it compeltely refreshes the set system settings, including the BIOS password. This again, is not the case with this model, as every attempt at updating the BIOS so far has been deemed useless.
BIOS Corruption - This again, does not work. It leaves the system in a dead state, usually the BIOS resets. This has occured once, as during boot we noticed the options to scan memory had changed and it took longer, but the BIOS password remained.
Backdoor Passwords - Again, do not work. We have tried the entire list submitted by Ekse.
Reset VIA Software - There are some hacking programs out there which reset the BIOS through the Operating System. And i think we can all guess what im about to say... They don't work. It may just be for this model, as i've not tried them on others, but the BIOS password for the FSC 1320D does not get reset using this applications.

So, the verdict?
Apparently you can submit your laptop back to Fujitsu Siemens for an 'Out of warranty repair', and they will reset it for you. Assumingly by changing the BIOS chip completely. The only downside to this is that it can cost anything from £50 - £150 depending on service charges and delivery costs. My opinion, wasting time on a laptop that is past its sell-by date like the FSC 1320D is really not something you want to be doing. Buy a new laptop and sell the 1320D for spare parts.

SOURCE: Can anyone help me on how to reset the Bios

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
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.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

How to remove the bios password of Asus eee pc bios password

On the motherboard, near the battery, you will see one of two things.
You may see three posts with a jumper on them. The jumper would be in the normal mode. You should see, next to one of the end pins writing that states CLR or CMR CMOS. Move the jumper to the that position and wait about 20 seconds. Then move the jumper back to the normal position and you should be good to go.
If there is no set of pins with a jumper, there may be two silver squares on the motherboard (very small) that will say something like CLR or RST. Jumping them with a screwdriver when the computer is disconnected from the power will do the same thing as the jumpers.

Reset pasword bios asus z53jc

To reset the BIOS read the information from this link: http://www.fixya.com/support/r7229632-reset_or_remove_bios_password
In case of your laptop the easiest method would be using software from Hiren's Boot CD (Kill CMOS will do the job) as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Forgotten password ASUS P4P800-VM

There is a blue jumper located just below the lithium battery on the motherboard. You need to remove the jumper and move it to the two pins on the right for about 10 seconds to clear the CMOS then move the jumper back to where you found it. That should clear out the password. It will also change all the BIOS settings back to factory so adjustments to the BIOS may need to be made after reset.
