How do I remove the keyboard from a Advent 7109B laptop, in particular the ribbon cable.

Most laptops are secured with screws from the bottom of the laptop. These screws maybe marked with a tiny keyboard symbol next to the screw.
When the screws are removed there is a cable on the keyboard that is attached to the motherboard. There maybe a connector on the end the cable, in this case carefully pull the connector by the tab to release the connector.
OR
The ribbon cable maybe locked to a connector on the motherboard, in this case slide the locking bar away from the connector to release the ribbon cable.

I suggest removing the keyboard and using a toothbrush on the contact point of the Ribbon cable where the keyboard's Ribbon cable connects to the motherboard, because sometimes they can oxidize. So, removing the keyboard and cleaning the Ribbon cable contacts has been known to resolve this type of problem, otherwise a new laptop keyboard might be in order.
However, to get the keyboard removed will entail some steps: First, the keyboard's retaining screws are covered up by a bezel. You can remove this bezel with a flat-head screwdriver by gently prying underneath it and lifting up. This bezel is located just above the keyboard and below the laptop's display screen.
Once the keyboard bezel has been removed, there should be two retaining screws that you can now see to remove it.
After removing the retaining screws, carefully lift up the keyboard because it is still attached to the motherboard via its Ribbon cable.
Before you remove the keyboard, you will have to UNLOCK the Ribbon cable connector and then carefully release the Ribbon cable - by moving the black tab up - about 1 to 2 millimeters. You should be able to move the UNLOCK tab with your fingernails. Also do not separate the Tab from the connector because it has to stay attached to the connector.
If you break the keyboard connector, you will have to replace the entire motherboard, so be extra careful and release the cable and remove the keyboard.

Removing the keyboard will give you the freedom to clean it in case there is any build-up or debris underneath its keys. Alternatively, you should now have a pretty good idea of how to replace the entire keyboard should that become necessary.

Hi,

Do it carefully..at your own risk..

HP 496771-001 Keyboard Repair and Replacement
Are you considering laptop keyboard repair? You might think twice if you happen to be the lucky owner of a laptop, because replacing the keyboard rather than repairing it could be a lot less expensive. Laptop keyboard replacement on this particular model is very easy and takes just a few minutes. Here is a quick HP 496771-001 Keyboard repair tutorial with step-by-step instructions.

Once you have purchased the new keyboard, all you need to replace the old with the new is a screwdriver and something plastic, flat and thin like a credit card or guitar pick.

Step one: Remove the two screws from the bottom of the computer that are holding down the HP 496771-001 Keyboard bezel. The bezel is the bar that sits right above all the function keys.

Step two: Turn the computer over, open the cover and insert the credit card or guitar pick between the bezel and the laptop screen. The bezel has pegs that sit in holes, you need to slowly pry up the bezel. It will make a bit of a popping noise as it is removed.

Step three: Now hold on to the laptop keyboard from the end closest to the screen and gently pull it away from the touch-pad end and flip it over. You will see the ribbon attached to the underside of the HP 496771-001 Keyboard. There is a little plastic connector holding the ribbon to the computer. To unlock it, carefully pull up on the two tabs; one located on each corner of the connector. Be very gentle when you do this as this is the one part that gets broken the most often when changing a keyboard. The ribbon cable will now be released.

Step four: Carefully pull the ribbon out of the connector and remove it along with the entire HP laptop keyboard.

Final step: To insert the new HP 496771-001 Keyboard, place the board face down so you have easy access to the ribbon. Make sure the keyboard is lined up so when you flip it back over the keys are in the correct position. Keep the ribbon straight at all times; twisting it could damage it. Place the ribbon in the connector; it only goes in one way. Once in place, push down on the connector tabs to lock it. Now flip the keyboard over and slide it down toward the touch pad and take the bezel and line the pegs up with the holes and push it in place. Then turn the computer over and replace the two screws you removed from the bottom. You can now power on your computer and see if the HP 496771-001 Keyboard works. If it is not working, more than likely the ribbon was not inserted properly.

There is not so much that could be done to repair a keyboard. Disassemble the laptop, check the ribbon cable connecting the keyboard to the motherboard. If the ribbon cable is loose, tighten it. If it is tight, replace the keyboard with a new one.

www.PCworld.co.uk is the support website for advent computers in the UK.

next to the F1 key and the windows key (2nd upper key and second to last key) are two screws, usually under some covering. unscrew and lift top edge of the keyboard towards the trackpad to lay face down. Undo the wire ribbon by lifting the grey or brown tabs and remove ribbon and keyboard. Then install the new keyboard by inserting the ribbon on the place. Lock down with the tabs and put the plastic prongs (close to the space bar) into the laptop body first, and then close keyboard onto the final position. screw back in and thats all. [email protected] for any additional questions.

The keyboard connector come in two types.
A plastic connector and usually has a plastic tab that you pull to lift the connector off, DO NOT PULL on the ribbon cable.
The other type is, a ribbon cable that is inserted into a plastic socket on the motherboard. To release the ribbon cable, lift up the plastic catch on both ends of the to release the ribbon cable. When you want to insert the ribbon cable, make sure the catch is in the up position before you insert the ribbon cable, then insert the ribbon cable and the push the ends of the plastic catch down to lock in the ribbon cable.
