SOURCE: [Ithr]checkpoint failure dell 8400 dimension

What can cause this error?

Well, this is the problem since quite a variety of problems can trigger the error.

1: the bios can be malfunctioning (a bios reset or flash can give a solution)
2: the cpu can be malfunctioning (this requires a new cpu)
3: the cpu socket can be failing (this requires a new mb)
4: the problem can be with bad usb sockets
5: even a bad uplink to a usb hub can cause this error to appear.
Did you change your monitor lately? I would chase down the USB things first...that and the monitor seem to trip the trigger...
Hope this get you started- I think you were right on target with the flash of the BIOS-try it again using the BIOS flash downloaded from the dell site...and to run the chipset just might
Good luck my friend, hope this helps, please leave rating, thank you kindly

Make sure you remove the jumper with the power OFF (not connected)

Disabling a Forgotten Password
NOTICE: This process erases both the system and setup passwords.
1 Open the computer cover.
2 Remove the jumper plug from the PSWD jumper to disable the
password feature.
See "Jumper Settings" to locate the password jumper (labeled
"PSWD") on the system board.
3 Close the computer cover.
4 Reconnect your computer and devices to an electrical outlet, and then
turn them on.
This erases the existing password(s).
5 Enter system setup and verify that the password is disabled.

A solid orblinking Amber power button indicates a voltage problem. This can be caused bya defective power supply or a defective motherboard. Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD drives. Look at the USB ports to see if any are damaged.

How to remove bios password of dell 2120

The software solution is probably easiest, but it requires having access to another computer. You'll need a utility that generates a master password based on your netbook's System Number. You can find such a file at the link, below. To get your System Number, boot the netbook and press F2 until the BIOS settings screen appears then select the Unlock button. You will see the System Number in the format: "XXXXXXXXX-XXXX".

Next, run the Dell.exe file from the link, below and enter the System Number. It will generate the master password. Use that password to access the system.

The hardware option is lengthier and requires disassembling the netbook and removing the CMOS battery. Removing the battery for a minute then reinserting, reassembling and rebooting will also remove the CMOS password. Instructions on how to do that are included, below.

Dell latitude e6500 cmos password

RTM = Read the Manual
Get onlineand got to In the google search box type: "DellSupport" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operatingsystem when requested. Look for Manuals and search them for CMOS or BIOS Password.I searched the manual and saw nothing that would allow you to reset the Bios Password. I even search the net and removing the cmos battery for a couple of minutes did not reset it. You can try taking the laptop apart to get to the cmos battery and removing it for overnight. That might clear it.It seems like Dell is trying to stop theft of the laptop. So they keep on their server who the original owner is based on the Serial Numbers and Service Tag on the laptops. You can call them and if you can prove you are the original owner they will probably help you out for a fee of course.

BIOS passwords for dell laptops require you to contact Dell technical support if you forget the password. they will generate a master password depending on the type of BIOS password. you cannot reset it by removing the CMOS battery.

I forget my Dell Vostro 1400 Admin BIOS password how can reset ..


Bios passwords are very difficult to bypass
you could try to remove the cmos battery and leave it out for an hour before putting it back in
sometimes this may work if you havent got a manual to show where the cmos battery is you can download one from this link go to support/downloads and search for the manual

also i found this link on the net you may find it interesting

if the link don't work then copy it and paste it into your search engine

also found this it makes good reading



IF THIS Did NOT WORK Try This Method

1 . THERE IS ONE JUMPER LOCATED ( near SATA hard disk slots mostly )
2 . jumper slot is of 3 pins , out of which , jumper is put into 2 pins
3 . remove the jumper & put into other 2 slots ( center one & the left or right which was not plugged into previously )
4 . start PC & u should go into bios settings without requiring the password .
5 . And there u can even change the password of bios settings .
6 . now it will ask u to put the jumper in its original position . put it there & restart
I have heard of people trying this a no of times & it seems to work
good luck
please let us know if any of these methods worked
many thanks

Dell Latitude D620 BIOS password help!!! I bought a Dell D620 and I noticed that some BIOS features are password protected. The previous owner said he doesn't know anything about it, so I'm not sure what...

Dell usually sets a default password as password or admin Try those first. If no luck go into the bios setup by continually tapping the exc key while the computer boots. If your licky you may be able to set yourself as administrator and give yourself admin rights. With admin rights you can do anything.
