Hi, To access or enter motherboard BIOS settings, on powerup either F2 or Del. If you just want to remove the password in your Dell Optiplex > The BIOS password may be cleared by removing the password jumper (PSWD) on the motherboard. This will also clear all CMOS settings: Open your casing, on your motherboard. find the CMOS password reset jumper (3-pin) on the motherboard; Remove the jumper from pins 1 and 2 and put it on pins 2 and 3 for about 5 seconds. Replace back the jumper on pins 1 and 2. Hope this be of help/idea. Good luck and kind regards.

Type password and I have replaced the battery in my computer.The message I am receiving on the screen is Diskette drive 0 seek failure.

For the diskette drive 0 seek failure, does the computer skip past this error without difficulty ? If it does, then you may ignore it. It is caused probably by your replacing the battery having reset the BIOS which is thinking now it should find a floppy disk to boot from. If you haven't a floppy disk, or have floppy disk drive you will get this message. I do, but I ignore it. When you power up, you could try entering the BIOS setup, by pressing for example, the esc, F1, F2 or F8 keys - for your model I don't know which, you may find out from the internet, your manuals, or the Dell website/help or support - repetitively before the computer starts,
( from Dell support - "You can enter the system BIOS or Setup on a Dell PC by pressing F2 at the Dell loading screen").and somewhere the BIOS setup there should be the boot order change this to CD first (no CD inserted unless it is bootable), then USB if available (no media USB inserted, some USB devices are ok), the HDD. You should not set HDD first because this will give you big problems if it goes wrong and you need to boot from somewhere else. Put floppy disk after HDD and the message will disappear.

I don't know about the password issue. I suggest you contact Dell support on this topic.

Dell dimension 3100 win xp home will not logon or go to setup/boot screen, only goes staight to black screen saying TYPE SYSTEM PASSWORD AND PRESS [ENTER] but it doesn't let you type anything. Also will...

The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

you may try to bring up your bios screen to see the boot order and then change it if you can....that would be while booting to tap the f2 or f1 key to get that screen ... then check the boot order, if it says position one is diskette, then try to change it...if you can't change it, get the bios updated then flash the bios....that should do it for you. post back your results

Recently acquired a Dell Inspiron 530s, having 2 problems. First, it won't boot right into Windows (Vista), asks to hit an F key (after hitting F1, it goes right into Windows). I went into Setup and a

It's a 'failsafe' - You will need to go back into the BIOS - double check the boot settings - and verify the HDD is set to Auto - make sure the RAM installed is the RAM shown on the boot screen.
Ok, once that is done reboot 2x - hit no keys - if it request F1 to continue, CTRL/ALT/DEL reboot. - go into BIOS, go to boot options find the part that states "stop on error" and disable that... reboot.
If that doesn't help Contact me here. I've other solutions to try as it is a DELL and I've dealt with them for years.

Someone has put a password on the BIOS - you must input it before entering the BIOS and the normal boot procedure. Because of the way IBM are build you can't reset the password by removing the battery, but only by performing a low level BIOS upgrade - which only a dealer can do. You will have to take it to one.
If you aren't the one that put that password and noone had access to it then the motherboard is dying - replace it before it's too late and all your data is lost.

Keep getting checkpoint errors, and have changed Sys Battery , reset Bios and when i boot it ,it goes to Dell logo and keeps trying to reboot. Windows will not load.

Try going to the BIOS and see if it reboots from there. If it does, then it is most probably a hardware problem. You can try re-seating the memory modules and If you have multiple modules, try them one at a time.
If it does not reboot while you are in the BIOS, then the problem lies on Windows. Get your DELL Restore CD or your Operating System CD and insert it to the CD-ROM drive. Reboot the computer and press F12 while seeing the Dell logo, that should give you the options to boot to CD-ROM. It will give you a quick prompt of "press any key to boot to cd..". Make sure you press the space bar during this time to initiate the boot from CD-ROM.
Once the Windows Setup loads, Choose "Recovery Console" to repair your computer. Just choose the installation you would like to repair (normally it's number 1) then it will ask you for the administrator password. By default, the password is blank, but if you set a password for admin then use that password.
Once you get to the prompt, Type this command. "CHKDSK /R" (without the quotes). It will initiate the repair for your OS. This might take an hour or so. Just wait for it to finish and it will automatically reboot your computer. Let the computer computer reboot normally. You should be able to get to your normal windows screen back.
Good Luck.

Blank screen on desktop (dell inspiron 530s); requesting a password.

Someone has turned on the BIOS password on you and therefore the PC will not let you boot up unless you enter the correct password. The problem is you cannot turn off the password option unless you know the password. I would start by asking other people who had access to you computer what they set the password to. If nobody comes clean, then you will have to call Dell Tech Support to get them to reset the password for you. They will give you a master BIOS password to override the one set and turn off the option.

Bios default password

The BIOS default password is just blank, and it is not asked.

When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.

To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.
