    AC adapter and Battery removed, you have to completely disassemble the laptop. Start from the top down, (LED/Power On Cover removed, Keyboard removed, Static shield removed, all peripheral devices removed, {CD drive, and add-in cards}, Palm Rest removed, hex nuts on back removed, Display assembly removed, and so on), Haven't taken one apart in years, so I'm going from memory.

Dell d340. need to enter admin password in bios to reorder boot sequence to accept usb first - its locked and i cant remember password. tried removing cmos battery and replacing but no good. help!


Try the backdoor password Dell

With a PSWD Reset Jumper Step 1Open the access panel to the password reset jumper if your Dell laptop has one. Consult your manual for the access panel's location. Some access panels have a tab you slide, while others are held in place with a screw.
Step 2Pry the plastic cover off the reset jumper with your fingernail. The reset jumper is a small pin port labeled "PSWD" with three pins. Put the plastic back onto the jumper over pin 1 and 2 instead of 2 and 3. Wait 90 seconds.
Step 3Pry the plastic off the reset jumper again and place it back onto the number 2 and 3 pins. Turn the laptop on. Repeat step 2 if the password is still present. Leave the plastic clip on pins 1 and 2 for a longer duration than last time.

Without a PSWD Reset Jumper Step 1Locate the reserve battery, also known as the CMOS battery, if your Dell laptop is not equipped with a password reset jumper. The CMOS battery's location varies among Dell laptop models. Consult your manual for the battery's location on your specific Dell laptop model. Many Dell reserve batteries are located underneath the main laptop battery. Remove the main battery and look for a sticker under it with instructions on removing the secondary CMOS battery.
Step 2Remove your Dell's reserve battery per the instruction manual or sticker located under the main battery. Removing the reserve battery resets the laptop's BIOS password. Wait 90 seconds, then replace the reserve battery. Reconnect the main battery.
Step 3Press the "Power" button to turn the laptop on.

Resetting BIOS password


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 usually looks like a couple of coin batteries wrapped in plastic and connected to motherboard by a two wires connector.

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

Several Dell Laptop 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

Hi, I hew problem with sony vaio pcg4g7p. Bios is protected with password and I cant reset it. password is unknown. thank you


You are going to have to contact Sony at: https://forum.sel.sony.com/viewtopic.php?f=15&t=6356&p=19414&hilit=BIOS+Password#p19414

and deal with them as they probably have a backdoor password that they will give to the owners. If you had access to your BIOS coin battery, then you could remove that battey for about ten minutes and the BIOS would forget the password. it is difficult getting into a lap top as the back has to be removed often to get access to that small battery.

Reset the bios password Toshiba A105-S2131 i cant do nothing, no dos, no windows when i just turned it on tha screenn of logo toshiba apears and then the password, if some can helpme ai really apreciate...


Sounds like you have a bootup password set in the bios. Press the key for getting into the bios and if it does not ask for a password then you can change the setting for bootup password.

If not then you will have to have the bios reset. In a desktop it involves unplugging the computer and either removing the battery or using the jumper to clear cmos.

On the laptop it would be unplugging it, removing the battery, accessing the internal area to remove the cmos battery to clear the cmos.

Can anyone help me on how to reset the Bios password to default on an HP Compaq 6710b Laptop? I have an HP Compaq 6710b Laptop. It is booting but it cant go beyond bios boot and i cant enter setup as it is...


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.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Bios


If you have lost your bios password, only way out of this is accessing the motherboard and resetting the cmos.
If you access the mothernboard you can reset the bios removing the little coin battery from motherboard for one minute.
There is also a 3 pins bridged contact, near to bios chip, if you move the contact on the other two pins it will do same as removing battery.
