How do you remove BIOS password from dell inspiron 1300?

Answer 1

This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

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.:

Answer 2

I just reset the BIOS password for an Acer Aspire 3620 by shorting the jumper switch on the motherboard. It was such a pain in the butt to find the stupid switch in the first place. Then it was hard to figure out how to short the thing, but this is how to do it:

1. Follow guides on the internet to remove the keyboard. Once you do that, you have access to the jumper switch. It is labeled "sw1", but you may have a hard time reading the label, since it may be hidden and is very small. It is not a component attached to the circuit board, you just see 8 lead bulbs sticking out, similar to this:

4 3 2 1

. . . .

. . . .

5 6 7 8

You can find it by locating the keyboard connector on the motherboard. It will be directly to the left of it. Turn your laptop off. Take a paperclip and attach one end of it to pin 1 and the other end to pin 8. Keep the two pins attached via the paperclip and start up your laptop. This should take care of the problem. If not, then try the same procedure, just with different variations of connecting the corner pins (i.e. 4-5, 4-8, 1-5, 1-8 according to the diagram above). Seriously, this was a major pain and Acer Support was worthless garbage. I kept pushing them for help and they kept regurgitating the same answers. It is really pathetic. Please use this and don't pay them $100. Good luck!
