"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.

I need to reset the CMOS Password for my acer extisia 4230


for that you need to open back cover of laptop .
Then find motherbord there.
Pull CMOS cell from motherbord for 10 minutes then refix it .
Also you can clear cmos with jumper find jumper near cmos cell named "clear CMOS " it has 3 pin
Set jumper i 2-3 position then power up 1 time then again set jumper in 1-2 position then it not ask for password.
Let me know if you need more assistance.
Thanks.

Not only the chip inside the motherboard can do it. All you have to do to DISABLE Jumper Setting near by Lithium CR2032 Battery or else in the motherboard by removing in a second (10 secs.) Then put back again and the BIOS were back into default setting.
Good luck!

On most acers it is two pads or a small jumper hidding under the ram.
With the laptop OFF remove the ram and check for J3 its is usually a bit more distinctive than the normal green pcb
You need to short that jumper out for a second or so
re-install the ram and boot up
You should now be able to get into the bios

Reset Cmos Settings for Acer Computers


There might be a jumper on your motherboard that's labelled CMOS, or reset... you just have to move the jumper to the other pin combination, power up your PC, then turn it back off and replace the jumper.
If you can't find a CMOS jumper, try unplugging your computer and removing the battery on your motherboard for a few minutes. When you turn it back on, your CMOS should reset to factory defaults.

Reset bios password


You need to locate the Cmos battery, not the jumpers, this is not a desktop.

Locate the Cmos battery, disconnect the battery for ten seconds, and Bios will reset to factory default.

Jumper settings


There is no jumper settings, it is just a small bridge aside the bios Chip. you bridge the two pins and power to reset cmos.

A much easier way is removing the Cmos coin shaped battery from motherboar for few seconds, and put it back, this will reset Cmos the same .
