Repairing a malfunctioning laptop keyboard (Unresponsive keys)

Repairing a malfunctioning laptop keyboard (Unresponsive keys)

Usually repairing a laptop keyboard that has a few keys that are not responding is straight forward. The cause is often that the keyboard ribbon cable has become unseated from the motherboard.
However in this case it seems that it was a slightly different problem, in that the connection had some dirt, or corrosion in it.

A quick brush up with an eraser and a can of air and the issue is resolved!

    This worked really well. My "6YHN" and "7UJM" keyboard columns were not working and this got them to work again! For reference, I have a Lenovo Flex 5 1470 (81C9).

    Thank you very much, I used contact cleaner on the base board connection and now the keyboard works perfectly.

    I spilled Lucky Charms cereal on my Dell Laptop keyboard. Now, the number keys and multiple others won't work. Please, can someone tell me what to do now? ( By the way, I'm typing this on my phone.. )

    It didn't work on my first attempt. But before I snapped the keyboard tabs back it started working. Although I did some extra steps like applying bit of water on the plastic flex connection that looked dirty before wiping it with dry cloth and then your eraser trick. I'm not sure how long this will last before it reappears but for now I'm feeling thankful for your video

    no luck, I tried several idea's and replaced the key board and I am back online, up and running, back in the saddle, thank all of my sister and brother you tubers . I had to make sure that I had the correct keyboard , one has lighted keys and the other is plain jane black . Some companies make it clear and others the item numbers are all the same except the last letter which makes the difference . Good luck!

    It's obvious well dismantling a laptop keyboard to look for lose fitted, dirty/oily, corroded or damaged connectors and, if lucky, ya might just spot a little piece of unidentifiable crap that just doesn't belong there – just as you did!
    Did you identify the key obstructing intruder anomaly??? Sure didn't look like corrosion…!
