I forgot my password on my 2010 dell inspiron laptop and I want to reset my cmos battery

It's located just below the RAM modules on the bottom side of the motherboard.

Remove the CMOS battery (CR2032 button battery) and reset the shorting plug to reset pin position.

go to biosremoval.com they can help, works for me every time.
my laptop had bios password hard drive password and windows password. which was unlocked using bios removal services from biosremoval.com

Unplug everything and remove the battery. Open it and remove the CMOS battery and wait 3 minutes. Boot it up without the CMOS, it should say password disabled, now you can put everything back together.

To reset the BIOS read the information from this link.

In case of your Dell laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

if it is a cmos pass word or even the had drive password you need the password or it is not useable. there is a way to reset it but you have to take it all apart and go from there.Laptops have an unbrakable cmos password so if it is stolen it is unusable unless you have the password

Disconnect the battery, unplug it, then open it up. There should be a small round battery called the CMOS battery somewhere in there. Pull that out. Then plug your computer in and boot it up without the CMOS battery. It should say password disabled. Turn it off, disconnect it, put it back together, and you're good to go. This only works if its the bios password that you forgot.

Hi,

If you have loast the password, to reset the BIOS password you need to remove temporarily the CMOS battery , so to reset BIOS settings.

Some model may be using NV Ram, in that case removing the battery is not enough.

The battery is located on the lower side on the motherboard.

On many DELL models the battery can be accessed from the side of DVD slot, battery slot, or RAM slot, without disassemblying the laptop.

On some model you may need complete disassembly (eg. Dell Le series).

The battery looks like a couple of coin batteries wrapped in plastic.

Before disassemblying or removing covers, always unplug adapter and remove battery.

On Dell Inspiron 8500 the battery can be accessed from a side , after removing the primary battery.

I think Dell 8500 can be set to use NV Ram to store the password.
In this case the problem cannot be solved removing primary battery, then accessing and removing CMOS battery for few minutes.

If you still cannot reset you have two way out.

Disassemble completely and access the NVRAM microswitch, or contact Dell and get master password.

You can also try one of this standard Dell factory CMOS password:

ALFAROME
BIOSTAR
biostar
biosstar
CMOS
cmos
LKWPETER
lkwpeter
setup
SETUP
Syxz
Wodj
Dell

if you want to reset itself to a password of your laptop is you can do, but extreme care because it is hard work, the battery of cmos can only see if you remove the keyboard on top of laptop and will lift at the bottom it will see the cmos battery, careful and good luck

you need to open the back cover of your laptop so that you can access the motherbaorad..ther u can see  a CMOS battery ..just remove it and after 20 sec ..put it back..it will reset th BIOS password...
