I just replaced the keyboard for my Lenovo 3000 N200 0769 laptop using the part #42T3338, an exact replacement for the original, several of whose keys had quit working after 2 years of heavy daily use. This part # has 2 screws holding it down, one where illustrated & the other above the F1 key. In addition, an official Lenovo 3000 service video shows 2 screws accessible only from the battery compartment that are supposed to be removed before the keyboard is removed. I don’t know what they connect to, but I removed them also.
The key difference was the keyboard’s ribbon cable connector, very different from what is illustrated in Step 2. My keyboard ribbon cable actually was attached from above, not below as illustrated here. There were 2 separate latch pins on either side of the ribbon connector, each about 3 mm high and 1 to 3 mm wide. Each latch pin has to be moved up about 1.5 mm to release the ribbon cable. If not fully moved up, the ribbon cable is still partly clamped in position. It would be easy to damage or destroy the latch mechanism if you are too rough. High magnification and bright lighting are important so you know what you are doing.
To reassemble, put the ribbon cable into the connector’s slot as far as it will go, hold in place while very gently pushing each latch pin back down into locking position.

Thanks Pal,

The 5 and 6 key quit working on the Lenovo three days out of warrenty. The IBM service people gave an estimate of $300.00 to repair. After reviewing your post I pulled the keyboard in 5 minutes, found a new one on Amazon for 22 bucks and ordered it.

Thanks again,

Doug

Great step by step instructions. I removed the keyboard only in my Lenovo 3000 N100. The ribbon connector unlocked just as you illustrated as did everything else.Thank you.

Almost Same for my Lenovo Y410. Except It has 2 keypad holders. Unscrew and install keyboard same as you explained.

Thanks for the post

On a 3000 n100, I noticed it was easier to pry up the launchboard by “popping” the tabs on the sides of the launchpad with a small screwdriver.

My keyboard had 2 screws holding it down. The one that’s circled in the image above and one just above the ESC key.

I also found locking tabs on the white keyboard connector. They were black and on each side of the connector.

Thanks for posting this!

My experience with my 3000 n100 was similar to Mr. Davis’, except that on my keyboard connector, there did not seem to be the locked/unlocked issue. My keyboard connector was white and anchored down with two metal pieces that I could not dislodge and was afraid to try to force. I just pulled — GENTLY — on the ribbon and it easily slid out. I merely paid attention to which side was ‘up’ when I took it out and inserted the replacement in the same direction (stiff piece of extra plastic facing down). I, too, only replaced my keyboard and the only other thing I’ll mention — which admittedly is a bit off topic — is that my keyboard (purchased off ebay from Hong Kong at a cost of $7 + shipping of about that) while it was listed as being for this model 3000, and is identical in most respects, has perversely moved around the function keys so that I’m now sort of confused as to how to reassign them (if that’s even possible). So if you’re a novice do-it-yourselfer make sure you get a good image of the keyboard replacement including the orange function keys (if you use those and they’re important to you). Otherwise, thanks to this site I’m up and running again and have all new keys. Thanks so much!!!

Almost the same for 3000 N100 – launch board cover needs to be removed starting at the right, cover is wider, going up to and including the gray screen hinge covers, and there are 2 screws on the top of the keyboard – I only replaced the keyboard, but the launch board looked almost exactly the same pre-removal. Thanks for the info!
