Question about Dell Latitude E4310 Laptop
1) Remove the AC adapter (Charger), and main Battery.
2) The CMOS Battery is now referred to also, as the RTC Battery.
Real Time Clock
3) Turn the laptop over, bottom side up.
The large rectangular cover in the middle, is the Memory Door.
Loosen the screws, lift on the Memory Door; on the screw side.
The RTC Battery is a coin-cell battery, in a plastic holder ('Bag'), with two wires coming out, that end in a small male plug connector.
Unplug the male connector from the motherboard, remove the RTC Battery.
Past this point cannot tell you exact location of those jumper pads.
Usually under a piece of Mylar plastic.
Often under the Ram Memory modules, or under the Wireless Module. ('Card')
The RTC Battery helps retain that password.
However there is also a capacitor, or capacitors; that hold a trickle charge - INDEFINITELY, after ALL power is removed.
Briefly touching the aforementioned jumper pads, relieves this stored trickle charge.

Hmmm, looking for jumper pad information I ran into this;
Looks like the jumper pad method will not work either,

applebook - 29th June 2008,
"There is no way to reset the Bios on the new Latitudes. Removing the power and PRAM battery does nothing. Everything in the Bios is contained in the EPROM flash chip and keyboard ROM chip. The E series uses a chip that cannot be reset by jumpers either."
Next plan of attack is to take;
1) Drivers license, or some other valid form of identification
2) Proof of purchase
3) Credit Card
,down to nearest Dell authorized repair shop, and have the resident tech obtain the Master Password from Dell.
The Master Password will be used to either;
A) Create a new password
B) Eliminate the password
Tech keeps the Master Password.

First off is there two passwords one for bios one for gaining access to the O/s ?
If its a system startup password basically you need to take the battery out for a minute and replace ( Easier to do on desktops )
or Flash the bios can't promise that would work or be easy on a laptop either. Would have to google that.

Restart your laptop and keep tapping F8 key the moment you see something on the screen. You will get a black screen with some options written in white. Select the option Safe mode and then you can create a new user with admin rights. Or else at the windows login screen press and hold ctrl and alt key and tap delete key twice and then it will take you to a login screen. Dont put any password there just hit enter. And you will be able to login with admin rights.
