Motherboard Repair Lesson! Dell Inspiron 7720 motherboard repair

[@lesleymunro4964]

You get good feedback not because you do dodgy repairs, you do cost effective ones with what you have got, and teach us about the circuits in the process. You simplify some very complex circuits. It is that reason why you get good feedback. Its the stuff you teach. :-) I hope you have a happy birthday, and enjoy your time off.

Make a video on my Asus a58c

[@MrOTcomputer]

@@unforgotenpromises I hate those motherboards. Small, thin, with a small D/C jack power supply port and built-in (can't remove) RAM memory and CPU. The built-in CPU always gets hot. If I remember correctly, there was something on a few asus modles like this that you can try. I'm assuming the problem is no power (won't turn on) or no display. You can try grounding the screw holes to the top chassis better. Around the screw holes is some light metal and if you notice where the TOP keyboard cover chassis touches the screw holes, it's suppose to provide some grounding for the whole unit. I used some tin foil pieces around each screw hole and then put it back together (applying some pressure) and I was surprised to see it come on. These boards are so cheap and sensitive to faults.

electronics free online course. I\'m not sure but ,if anyone else is searching for understanding electronics pdf try Letza Easy Electronics Lessons (should be on google have a look ) ? Ive heard some awesome things about it and my buddy got excellent success with it.

[@jkaryskycoo]

But he glues when he should epoxy. He hot glues broken hinges. He doesn't have very common parts on hand and does repairs that won't last 6 months.

[@stipe9609]

Please can anyone tell me where I can buy few broken laptops like this, I really want to repair something and learn.

[@acopoli2400]

Excelent!!!!!! this is people genius ..... i don't understand and speak english (google translator now work) ... but as far as practical moves he shows, this man literally doesn't even need to say anything .... what he does is magic. ... each honorable friend!

[@NicholasDaniel11]

Sorin you have grown me sooo much as a technician. I will continue to support u Sir!!

[@computersrepaircotesaint-l7407]

Thats great video sorin. We learned the 19 and 3.3, great lesson for the 5 volts rail.

[@YugoZex]

Hi people, let me try to explain how this repairman works. This is old (Russian, Romanian, Serbian,Polish, Slovak....) repair school method. In my country repairing like this was wide spread. It's easy to troubleshoot card faults and swap cards and there you go. In poor countries like Yugoslavia back in the days this was only method for repairing electronics, mostly repairman did not had schematics, they had to improvise and do some tricks to repair, 99% success. Back in the days there were not laptops but most electronics was imported and schematics was hard to find. So anyone that have bad opinion I challenge you to do what he is doing without schematics and also he is teaching how to find other way to repair. Swapping elements is easy try to be innovative like him. GOOD WORK...

[@pooterist]

Positive feedback - well earned, I say. I enjoy your videos and the relaxed yet very practical and correct approach to solving real world problems. Have a nice, relaxing day off for your birthday and keep it up the good work.

[@rokrjock33]

You sir are doing a great job talking your precious time to teach people what you can for free. I can understand the guys who post negative comments as they are the engineers the stiff upper lip kind who get offended if everything is not porn and proper. They dont understand that you can't spend time in doing research when on a job as it is not priority. In fact there could be businesses who would not let someone do what you are doing, teaching for free. The priority here is to get it up and running and ensure it doesn't come back after a short time as then it'll be another repair and for free. You stiffs will be surprised to know that people are doing these repairs without even knowing what these parts are or do. In these videos our instructor does have knowledge but not the time to go into the kitty gritties and he never claims this is is how it is supposed to be done. He clearly says it is how he does it because it works for him and you can follow proper procedure and do it in an hour, I can't afford to do that. Anyone who wants to follow him is doing it by his or her own free will, why do you guys have issues here. The op never claimed to be making people engineers he shows them how to repair stuff the ones who want to learn it all can go to a different channel or to college for a Graduate's Degree in Engineering.

Hi, I am watching your videos for some time now. I wanted to learn about fixing laptop motherboards. Thank you very much for all your videos, powerful, simple and straight to the point. It has been an honor to learn from you. All the best.

[@abebeashenafi7943]

I am very impressed by your different maintenance activities to enable others motivated .Good job sir .keep it up

[@lastawake2822]

Sir, thank you for inspiring and for teaching me. From Poland, you recieve great thanks! :D

[@ErditCironaku]

Thanks, Sorin. I follow you on every repair video you do. Big fan on how you resolve things and the mastermind behind it. I returned to this particular video because I have the same situation with an HP laptop, replaced the SIO and a chip shorted. Now I have all the voltages but no lights at all and no power. Your method following the 5v maybe will help me. Thanks for all you do :)

[@lookoutleo]

you are genius , i had no idea those dead motherboards were fixable outside of a lab, you have 500dec blow lamp , linier power supply , a multimeter and a way of magnifying the job. i'm amazed

[@nontasanastasios7612]

"The power button is ok but its not powering on, maybe its upset.....could be..." Thanks for the great laugh

[@mrdovie47]

Happy Birthday! I was able to find a shorted capacitor on the motherboard using your ideas. I put together a PWM power supply and turned up the amps where the short was and the capacitor got warm, so I unsoldered it now 3.3 volts, 10 volts, and 5 volts work. It is an eMachine M6810 now to remember how to put everything back! Thanks. Here in USA they would tell you the motherboard is bad, buy a new PC.

[@mrdovie47]

The laptop is working, Windows 7

Clean chip area, pre-tin your pads, use quality flux before soldering new chip and it will solder like butter. I appreciate your time and knowledge you share with us, but you should consider using a fumes extractor take care of your health! Thanks for sharing.

[@pgsss6354]

Great video Sorin! But I have a question. At 20:04 you 're testing 19V at a point on the PCB. Which is the exact point? (also and the rest of the test points are not clear, it would be very good if you could show them clearly. And also the logic of spotting them without the schematic!!!)

[@anselmosahlin3057]

Hello sir, I just Learn new ways of fixing the io chip which demands using a flat tip soldering iron it's very easy and assuring I'll make a video, and send you on how it's done. By the way, that 5v injection was so great, an amazing discovery for me. Million thanks again

[@bonbonpony]

41:07 What pins do you short to power it on without the button? I have a separate board with a button, which is connected to the motherboard with a ribbon. There's a whole bunch of wires in it, because there are also some LEDs on the panel with the button. So I'm not sure which ones should I short, and unfortunately I can't simply test it with my multimeter because the probes are too thick for the wires on the ribbon :q
