Sorin is so addictive. Who can agree with me. The way I just love you.

[@phillipsvanderwesthuizen800]

No peripherals, no circuit diagram, no idea what laptop and still it gets fixed. Magic (or a boat load of experience). 👌

[@markkay8117]

No magic here my friend! only experience and nothing more!

[@daffyduk77]

@@markkay8117... plus a level of skill applying his almost intimate familiarity with his diagnostic tools & in-depth understanding of components & their relationship to board power functionality which resembles magic to many of us mere mortals. Even the soldering seemed ridiculously simple ... to him.

5:41 - "If you are new on this channel..." Because he knows, that we old subs know what we he is doing :D We demand merch "Of course I will replace shorted capacitor" and "If there is no capacitor, there cannot be short" ! :D

I don't watch movies anymore, I watch sorin fixing electronics, you pay a lot of money to learn in a university, with sorin is better

[@user-pe3yi7hn1s]

"We have pictureeeee !" My favorite Sorin response !

[@dontrotter1099]

Elementary my Dear Sorin! The logic you use is fantastic.

[@andrewverran3498]

Probably one of your most informative videos..Bravos!! Also I don't think a DELL motherboard would ever have a HP power jack? Sorin is 🤴 👑

[@carlosgarciaoropeza5480]

(10:47 ‒ 11:55) Brilliant deductive (brain) analysis to find the cause of the failure. Still in disbelief (if I hadn't seen it). A sincere congratulations. Thank you very much for sharing. All the best.

[@andythomas7931]

Motherboard whisperer amazing to watch a consonant professional at work feeling the zen of what he does

[@Hejazi1365]

I enjoyed watching this repair.good job Sorin❤

[@dimitrismaster]

Either invest in a quality hot tweezers station,or just replace the cap with a soldering iron.I never use hot air to remove and replace just a cap.Only soldering iron with the proper tip for each job.Yeah it takes a minute longer but its safer imho.

[@a.wagner9479]

A very pleasant explanation and a good job carried out. Well done!

[@galacticpeace8459]

Great Thanks Sorin

Thank you very much 🎉. All schematics are in your brain 🧠

[@mvlad7402]

Great instructions! Will keep it in mind. I have board to play with

[@AbdulMajeedHamid]

Because of you and northbridgefix I have finally began my repairs journey. So far so good

Nice one 🎉🎉

@Electronics Repair School Can you do a video on all of the repair devices that you use and vivid detail on what your devices is used for?

[@KellySimonsson]

thank you for an awesome video! :)

[@kalmadolang3583]

you are so great sorin,, great than alexander😊😊

[@TheKosssteK]

Sorin, can you explain how you have so many things hooked up to a power supply? Those power adapters + normal multimetr leds.

[@hasankaperera771]

Thanks sir

[@mavesoft3284]

5:43 LOL!!!!!!😆

[@laptopDoctorKZN]

U can check the io schematic and there are usually 2 pads there . U can bridge with a tweezer the button is linked there.

[@laptopDoctorKZN]

Bq24780s. Check regen pin. If no 6v the there a short somewhere

[@Trustsimo07]

thanks. 👍

[@anatolyvilanculos6513]

Sorin always dodge, but I like to watch his videos because I always get a new idea's to fix stuff without dodging 😂 even when sorin dodge 😂😂

[@William51115]

nice one

[@amannetsohmor6943]

Thanks Sorin, this was awesome. I want to ask for some video links or websites that helps beginners in understanding motherboards structures and components. If you plz.

[@eugrafcmg]

Just look through the history of this channel because Sorin has amazing tutorials and courses

[@danytoob]

Sorin, our electronics wizard ... fixing a mystery board with no computer to put it in. Proof there is no substitute for experience (and a big brain ... lol!)

[@jozsiolah1435]

It still needs a good battery to fix the boards, because the battery causes them to operate at first. If the battery is bad, the whole laptop will become locked, if the battery is new or in good condition, all functions will turn back on.

[@Dr.muthanna]

awesome

[@JurdzLights]

My way of testing working motherboard without monitor is using usb keyboard. If the numlock or capslock respond to my command then it should be a working one.

[@andrewverran3498]

Good to know , or buy a HDMI converter cable.

[@frankmormando3917]

You are so funny! I am thoroughly confused about replacing caps, but I think you are doing it on purpose 😂

[@carlosgarciaoropeza5480]

@Frank Mormando: Master Sorin is just joking with us (his subscribers). I'm sure he replaces them either with new ones or from a donor. I was convinced of this with a video from 6 months ago (November 23, 2022) entitled: Do you really love your electronics? All the best.

[@frankmormando3917]

@@carlosgarciaoropeza5480 ok 😂

[@maklogetrich2378]

he desolder the caps after video recording 🤣

[@Trex0Pol]

@@carlosgarciaoropeza5480 There is no need. Trust me, there is enough capacitors removing one won't cause any issues.

[@Mr.Nabil.Belhaj]

I fixed this same laptop before by reverting it to integrated graphics and prevented power from reaching discreet graphics because these laptops overheat and stop working due to the mediocre cooling

[@tonyrgnash]

Hi Sorin

[@PracticalKnow]

The original chip was likely removed & re-soldered (and killed) in search of the short - supported by the fact that that *they never found the shorted capacitor.*

[@bernarddavies4145]

I have the donner type board and went step by step. I found 3 volts at the switch connection and the board fired up lights on and seems to be working with out doing anything lol

[@leerzeichen1910]

perfect!

[@laptopDoctorKZN]

Use hot tweezer to repair or replace capacity

[@burntkorn]

I’m looking for a MOSFET, unable to find it on Google or other websites. The numbers on it are too row 0588, in the middle it’s IR 631K and above each pin is G5,7H, and then DB. Any idea where I can get this part? It’s a TO-220 case

[@user-xy7pj9sc5w]

Nice work done I need your help I don’t know if I will be privileged

[@sebczajna700]

Hi, which type of multimeter have You aktualy? Best regards 👍

[@teslasapple]

Yup!

[@dannechita8577]

How you know witch side is + in a capacitor?

[@ElectronicRepair.Serbia2023]

Sorin This model does not exist unless it is HP Elitebook 850 g3?

[@carlosgarciaoropeza5480]

If, according. With Part Number 6050A2728501-MB-A01 for that mainboard I find that model that you also indicate here in North America. All the best.

[@weerobot]

Cool...

[@bakutools]

which kinds of multimeter do you use?

[@andrewverran3498]

Uni-T

[@khleviejuncaseres3879]

For how many videos i only see once that you replace a capacitor. 🤣🤣🤣 And this the second time. 🤣🤣

It is funny that people send a donor board with a faulty board.

Dont worry he will change the capacitor later :))

Capacitor gone short, laptop stop working, somebody tried to fix it , got BQ chip damaged. Just a guess.

Again a great repair but sadly didn't make a properly calibrated capacitor. ☹😃☺
