No one can teach like Sorin. the best of the best
If you put water on the board to remove sugar you then need to get a paper towel or something to soak it up. If you just apply heat to evaporate it you WILL NOT have removed the sugar. At best you might have spread it around more thinly.
Only Sorin can fix a water damaged laptop with water, come on, if this is not true, what is...!
"you will get brain damage from schematic " 😂
So thing to remember from this episode: 1. Always check if cleaned connectors are really clean and dry, 2. Don't loose removed elements in case it's not a fault - You don't want to modify schematics :)
I noticed that you "cleaned" the board by adding water and then you scrubbed the area with a toothbrush, then dried the area with hot air. You really need to wet the area and then wipe/blot the water off, or flush the area well with water. Otherwise you are not removing the sugar/salt that was dissolved in the water. You are just spreading it around. I have spent many hours watching your videos and find them extremely informative and interesting. I have a pile of older laptops that I hope to restore with your the help of your videos just to see if I can do it. Thanks for sharing your troubleshooting methods.
So sad to see that for all your experience you chose the "carpaci" approach. True quality is when you restore it to factory design, not increase the current 10 times (at least, since pull-up resistors are usually 10Kohms but for mobile applications could start from 20Kohms to not consume current for nothing) on a clearly faulty circuit that leaks current somewhere. That leaking current will cause failures in the future and will break something. But it's good for business to have recurring clients I guess...
It is actually a very good idea to remove sugar(sweet) liquid damage with water! But THEN... instead of drying the water with the hot air (which still may contain sugar that doesn't evaporate), remove water with... alcohol :-}. Alcohol has almost indefinite ability to absorb water (with or without sugar) and still being an alcohol. And it evaporates very quickly - much quicker than water...
At the end I dont understand well the problem. You replaced the resistor near by the super io and you took out the one on the same line near to the power on Button. So the problem was this 2 resistors?
i heard from some else to always remember if you are disconecting the display make sure the battery is disconected first because those pins have voltage whether you push the power button or not. to avoid shorted display when removing take it out.
When I was young, I did work on an Intel Motherboard and Motorola boards making factory. After the boards are made, they put it in a conveyor that looks like a big washer machine and they use Cascade to clean the boards. After the dry cycle, it looks perfect. From that experience, if I really need to clean a board, I just put in my dishwasher with Cascade soap. Be sure to have the hot dry selected.
Thank you Sorin, being an IT guy with his own shop from 14 years and 30 years worth of software and hardware knowledge, but not electronic. Getting enough courage will broad my shop services, in times like this makes the difference. As you said in another video we have to surrender to electronics fault as a repair shop, but i'm trying hard to make an inversion and dive into this world.
Sorin's proper calibrated resistor !!
I cannot believe how much this man have knowledge this is absolutely amazing!!! I'm so far away but I wish I could meet you in real life! I will be happy to have 10% of he's knowledge! Man hat to the ground!
that was a great vis. thank you :) From beginning to end unbroken video it was all the trials and tribulations and fault finding in real-time. Thank you :)
Master Sorin I love the way you fix things, you are a Hacker!!!Thank you again for sharing your knowledge with us!
Thank Sorin
Hello Sorin, as always magnificent work, you are a crack and I admire you, thank you for showing us your work and learning from them.
Wow, real electronic lesson. I enjoy a lot looking at your videos.
We know what we are doing 😊😊.
