Lenovo IdeaPad 320s Burning Smell When Plugged In -  

I was shouting at you to check that capacitor first. It didn’t look ok from first sight! 😂 Great video Graham! 👍

Hehe, happens to us all from time to time. We were all shouting at the screen. Love how straight up you are showing mistakes. Great content as always.

I was totally yelling at the monitor "That Cap is cracked" arrgh! But you got it! Yay!

Congratulations on 400 videos.

Nice video. The coil concerned is to filter the ripple created by the buck regulator getting out rather than filtering noise coming in.

Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE due to the rotten & outdated standards of education here in the Philippines. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.

In this case just check with an oscilloscope in and out of the inductor of the 3.3v working regulator .. just to see if there is some "stabilization of voltage involved"

Thanks for sharing your thought process it really helps us newbies.

That music while you works always makes me think of some cheesy romance scene from an 80's teen flick! Hahaha!

Great video again thnx.

Great work

Manufacturers use these inductors as cheap fuses. Replace them with 0.1mm (not just blob) wire and don't think too much about them.

love the kersploded phrase Graham LOL

Kersploaded- my new word of the day, love it

Always. Check. Your. Assumptions. Applies to me when debugging software and, apparently, also applies to electronics 😜 Good job!

i get things wrong at first and fill the thrashbin later. U made a mistake and got everything fixed in the end. Congrats! 🎉

loving the haircut

Great explanation as always, im going to say, i think i see that iffy cap but im not 100%. Nice Vid, keeep them coming!

Hi and nice video ! Other option was inyect 1 or 2 volts and look who burn.-

hello good sir love the vids

earlier on you can see in the microscope that the cap have a crack on it.

Happy Haircut too by the way lol.

what u mean welcome to Adamant? where did #LFC go xD

I was wondering to be honest why did you not check that bad looking cap first !

It actually worked🤭 BTW your brain is just normal. I was expecting those burns becomes carbon resistor.😁

Been there, done that 😅

Ha! I saw the cracks in the capacitor right away.... do I get a prize? 😁

Are computers similar to automotive where one part fails causing other daisy chain parts over work leading to a future of failing?

Hi! Where do you get the schematics for any board?

Not enough cider?

Exelkent😊

L7500 Graham, I'm sure it said L4500

Maybe consider to buy a new multimeter instead of the slow reacting Vici . Thanks for the Nice video’s !

you need a proper microscope (with depth info) . great work

👍👍😎✌️🤟

Tip for the tip - use fine diamond file (cheap - commonly sold for fingernails) to sharpen the probe tips, gives them the o-scope probe tip "bite". In my experience most "gold" probe tips are plain brass all the way through, no need to care for an outer coating being damaged. (can't tell about expensive probes that might actually be gold plated)

it's allways false capacitor

Please please please don't start using "go ahead" over and over ----- 8 mins 37 seconds
