Where is dell latitude c510 cmos battery located?

It is buried on the motherboard. Really buried. You have to disassemble the whole laptop to get to it.

Dell

The official method is to contact Dell Technical Support. Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Latitude. If the current user is not the original Latitude owner, Dell will transfer the used Latitude's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

• For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:
  • Locate the 3-pin CMOS password reset jumper on the system board.
  • Remove the jumper plug from pins 1 and 2.
  • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
  • Replace the jumper plug on pins 1 and 2.

Try the backdoor password: Dell

The another method is: 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, and remove the battery and power cord
( if it is a laptop ) before you continue.

Here is a picture how it looks like:



The default setting is:pin 1 to 2, to clear cmos: 2 to 3.

Best of luck :-)

Forgot dell admin password? I also met the same trouble with you, but i used Smartkey Windows Password Recovery to help me to reset forgotten windows password, and you can see the detail direction from http://www.recoverlostpassword.com/products/windowspasswordrecovery.html.

If you need to reset the Admin Password, you will have to call Dell. No Jumpers, no user accessible reset.

The password is not on the battery it is in the volatile memory.

The battery supplies the power to the volatile memory to make sure it retains its settings.

If you have removed the Cmos battery and when you put it back the machine still has a password then the password is written into the non-volatile memory and cannot be re-set that way.

Get a hold of someone with ERD Commander and they will drop the password off in a couple of minutes

The BIOS password is stored in CMOS memory which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine.

Hope you find this information usefull.
your feedback is appreciated.

clear the cmos, or remove the battery for a few minutes, that will clear any bios password
