Question about ASUS Computers & Internet
My son set the bios password and forgot it
Restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer
As the computer is booting repeatadly press the F8 key as the computer is booting
If done properly the user should get to a screen similar to the below screen.
Select the option for Safe mode command prompt only
Windows Advanced Options Menu
Please select an option:
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Start Windows Normally
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
select safe mode with command prompt
Then type at the C:\> prompt: type
and hit Enter. You'll see a dash (-) at the DEBUG prompt. Now type:
o 70 2e
which will show as -o 70 2e at the DEBUG prompt. Hit Enter. Then type:
o 71 ff
and hit Enter.
and hit Enter one last time to quit DEBUG back to the C:\> prompt.
Now you're ready to reboot your PC, and press the appropriate key or key
combo (look it up in your motherboard manual if you don't know it) to access
your BIOS Setup.
Youll notice the password is gone.
If this fails try typing
At command prompt type debug
you will get a - prompt where you can type the following (<enter> means press enter, not type enter*)
MOV AX,0 <ENTER>
MOV AX,CX <ENTER>
OUT 70,AL <ENTER>
MOV AX,0 <ENTER>
OUT 71,AL <ENTER>
INC CX <ENTER>
CMP CX,100 <ENTER>
JB 103 <ENTER>
INT 20 <ENTER>
<ENTER> just hit enter on this line
Basic BIOS password- works 9.9 times out of ten
If this fails you will need to
Select safe mode with networking to download
you could download all of these or just one save them to a usb drive for later use if one fails to remove the password
At some stage you might need to press Ctrl+Enter rather than just Enter if on a Dell Latitude E5410

Since you forgot the password best thing to do is make the cmos forget it. The way to do this is remove the cmos battery. Take it out for several hours then put it back in. This will reset the cmos and you should gain access.

In the model 280 Optiplex, remove the jumper, they have two pins only, turn on the computer, wait for 1 minute. The jumper is located close to the power plug, in the right side, you read PWD, theres is it, i did it and working fine...

Tips for a great answer:
The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps
