Remove or disconnect the RTC/CMOS (coin-cell) battery from the motherboard. This will reset the BIOS to defaults and the password will be gone. Here is the Coin-cell information

Let me know if any further clarification/ assistance is required.

Good Luck!

My notebook needs administrators or system password

If the password is right when the computers starts, you'd need to remove the CMOS battery.
The CMOS battery is a battery that lets the computer store the time, bios settings, and the bios passwords. If you remove that battery, it will clear them all, and reset it back to defaults.

If the password you're referring to is the one for the windows, take a look at Ophcrack. They have a file you can burn to a CD, available here: , which will crack the password for Windows XP or Windows Vista computers.

Pls i want to unkock my dell latitude d620 Administrator password

you forgot to tell us what password.
Is it a bios password or windows password?

For Windows Password, As far as I know , there are two main methods to solve the windows password problem as follows:

1st Method:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from \Control Panel - User Accounts\.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

2th Method:
Windows password Recovery software:
for example: Any Windows Password Reset 7 . It is easy and convenient to use.

For Bios Password, also two methods.

1st method . Open you computer box and Discharge to the Board manually

2st method . use BIOS/CMOS Password Recovery Tool

Hope it help to you.

How to remove password on most of Dell laptops

The only way is to reset the bios. This is very easy on desktops because you can get inside of them easily to either remove the CMOS battery, or flip the reset jumper.

You will have to remove the laptops casings, find the CMOS battery, Its about the size of a quarter. Remove it and let it sit for 10 minutes, then replace it and reassemble the laptop. There may be a jumper to reset it as well. it is usually JP1. this is a standard for CMOS reset jumpers.

Forgot my password on my laptop it is in the bios and I can't remember how to get into the bios to change it

If you forgot your BIOS password, then you can reset it by clearing the CMOS settings. Do to that, you have to remove a small battery present onto the motherboard in your laptop. Remove the back panel of your laptop and locate your motherboard carefully. There you can find a small coin sized battery which provides power to the CMOS to remember your system date, password and other settings. Remove that battery from your motherboard and replace it back after 15 mins. Then fix the panel back and restart your system. It will prompt you for setting up BIOS or to restore default settings. Now your password should also be cleared. I hope this solves your problem.

Dell latitude d620 power on password can't remove

No need to short out any pins, shorting out pins allow you to reset the BIOS quickly. When you leave the BIOS/CMOS battery out overnight, this will reset the BIOS (you only need to leave the battery out for 1/2 + hour to do the same thing).

Forgot my bootup logon password

The only way to reset your boot logon password is to take out the battery for about 5 minutes and that will clear the password in CMOS. The battery is located on your motherboard. I know it is tough cause its a laptop but just go slow and remember to put the battery back in the same way you took it out, it is easy to put in back in reversed.
