The Keyboard Cable STAYS attached to the Keyboard.
It disconnects FROM the motherboard's connector.

The Keyboard Cable has NO connector on the end. It is a FFC.
Flat Flex Cable.
One example of a Flat Flex Cable,

http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg

The flat metal terminal bars MUST be aligned back in the SAME position, as they were originally.
For this reason you may wish to take a Sharpee marker, and make a mark on one side of the cable.
Then make a matching mark on the same side of the motherboard connector, BEFORE you remove the cable.

The motherboard connector is a type of ZIF connector.
Zero Insertion Force.
It is composed of two pieces, but does NOT come completely apart!

The bottom part is larger, rectangular shaped, and is stationary to the motherboard.
It is the BODY.

The upper part is smaller, rectangular shaped, and is movable.
It is the Locking Bar.

ACCORDING to the video the Locking Bar is the Slide/Wedge type.

DO NOT use a metal tool as shown. One slip, and you can damage the motherboard! Geez!

Use your Fingernails, or Thumbnails.

The Locking Bar slides up. Up towards the LCD screen, or away from the Body.
It ONLY moves about 2mm. That is a little larger than 1/16th of an Inch.

IF, the Locking Bar is broken, or the Body, you are looking at
-> MOTHERBOARD REPLACEMENT!!

Hence why I am being so detailed.

More detail on unlocking this type of motherboard ZIF connector,

A) Locked position;

B) Unlocked position;

There is another style of Locking Bar used, however.
The Locking Bar flips up to a 90 degree position, or also can be stated as Straight Up.

Just to make sure I'm going to include info for it too;

U need to be more specific or detailed with ur question

Please try a new keyboard! I had mine go out and did the same thing! I hope this helps!

Hi,

are you using a usb keyboard? A lot of systems require a ps/2 (purple round connector) keyboard to access the bios settings and anything on the startup screen unless you have set usb on boot in the bios settings. I would try connecting a ps/2 keyboard and see if it helps.

when booting hit f11fast and over and over til the setup options starts or f2 for the bios to pop up and route though til ya find the keyboard options ok if locked unlock or enable it, it is in one or the other or upon boot hit R many times til the recovery tool pops up and then do a HD error diagnostic on it to find the problem ok the fixist good luck and have a nice day

locked how?

not working at all?

try turning PC off...disconnect and reconnect your keyboard and boot your PC back up

This fixes issues like this 9 times out of 10

The connections might be loose. Please try to unplug the cable which connects your keyboard to the computer. If that doe snot work try an alternate keyboard and see if that works.

If that still does not work, then most probably it is the keyboard port on the motherboard which is faulty.

You can try updating the BIOS. Click HERE to get drivers, support and user's manual for your boar.

This link is for the owners manual on that board,
http://download.intel.com/support/motherboards/desktop/d850mv/sb/mdmvenglish.pdf

On page 47 it states F2 is used to get into the bios, press repeatedly while booting so you don't miss the window, and of course check you keyboard, it should flash the caps,num, and scroll lock lights on boot.

Hope this helps
