man I just discovered your channel like a week or so ago, I have been binge watching your videos. So so good. I was really into electronics when I was younger, like building all types of stuff with 555 timers, jk flip flops, shift registers, caps, etc.. You have lit that fire in me to get back into it. Thank you.

I've spent the past 20+ years performing the same type of repairs as you so I know the amount of experience (plus equipment & tools) it takes to inspect, troubleshoot and repair. Your skills are top notch! Keep up the excellent work.

Outstanding work as always, I love your work. You inspire me to do micro soldering, because I'm a learning technician in Jamaica, quite young to the work and your videos have taught me a lot. Thanks for being such a open and fair guy, most technicians don't share the methods of the work, especially in such detail. Keep being the great person that you are and may God bless you.

Hi Alex, most EC programmers who work through the keyboard port have the feature to test keyboards. You can see if a key is working or not, stuck or not. But for about 30$ you can also find keyboard testers.

@@kdilac8879 No. Keyboards are "analog" (two circuits are switched together on the keyboard matrix when a key is pressed), which the testers can measure. Touchpads have their own controllers and firmware, so this cannot be easy standardised.

I can only guess, but it appears those traces were probably made too thin, the coating peeled off, then the traces oxidized to nothing. Slight defect in manufacturing. Honestly I'd of guessed the keyboard wasn't any good before i thought it had this problem... you made the right call.

@konatadesuka Жыл бұрын

Common issue when you keep your laptop on your lap or inside a backpack in the summer. Sweat and moisture finds it's way into the board. I had several issues with my daily driver laptop unti the keyboard was completely gone and that was the end of it. The keyboard is welded to the case so into the bin it went.

Yes, it happened to me also once for a TV remote. Around 2-3 test pads were totally gone, due to which none of buttons on remote was working. After connecting those, it started working. I thought it could be due to sweat (salty moisture) from hands went inside remote. Not sure how it can happen to a laptop though.

if you use a gaming laptop at your legs, you will sweat there and the coolingfan of the laptop sucks in the moisture , the rest you know.

Probably the corrosion was caused by condensed water which happens when you turn on a very cold laptop in a warm and damp room without waiting some time. A failure of multiple keys is often caused by an issue with only one signal line because the keys are connected in a matrix.

@ImranOO7 2 жыл бұрын

Alex, I hope you read my comment. I'm wondering, what you do in cases like that, when the part you ordered is not necessary for repair. Do you keep it in stock, as it might come handy in the future, or do you send it back? I'm wondering what's more sensible from a business standpoint - having that bit of cash "frozen" until somebody comes with compatible laptop and issue or sending it back so you get cash back (minus shipping probably). Keep on good work! 👍
