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.

Sirs I have not made any password for entering bios setup for compaq presario x1370 us, but when try to enter bios setup by pressing F10, display for administrtor password appears. What password could i...


But there is no need to worry. There are many known ways to reset / remove / bypass the password: Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings. If it fails, then try to remove the battery for at least one hour. B. By Using the Motherboard Jumper: 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.

How do i fixt it. it has crash and now asking for a pass word and i dont have it the screen is black


here are 2 password type first 1 is bios password if tell me about your bios password it prompt when u powerup follow procedure below

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

And if u tell about windows password
Then when you power up the computer press F8 key then enter in safe mode then wait until it prompt for user password

then enter in administrator then if u able to enter then reset your password.
But if u set and forgot default administrator password then u should need win xp recovery disk.

Forgotten the password , without it coputer wont boot


Sounds like you have set a password in the BIOS. If you have forgotten the password then you will need to reset the BIOS settings to their default. This is usually done by setting a jumper on the motherboard. You are going to need to get your motherboard's manual and find the BIOS Reset jumper switch. Once you set this jumper properly, the settings in the BIOS will be reset to their default values.
