Another great repair by the PS master! I don't understand why all the silicon - some PSs have it & some don't.
good to see you've got that little component tester that checks capacitor ESR.
FYI, I've seen vids on YT that modify them with a power switch so the battery doesn't drain so fast when not in use.
I've learned so much from you please keep on teaching us
Excellent demonstration brother, keep up the hard work.
Excellent thanks for sharing this informative video keep sharing❤❤❤
it is my pleasure
Great repair! Thanks and take care!
best regards
Excellent sir! Thanks for sharing!
it is my pleasure
Very informative content. Shukriya Maestro
thanks a lot for your valuable words. have a great weakend
@@HaseebElectronics you do the same !!
I really like the work you do on the electronic plates with the microscope. I am enraptured.Keep it up.. thank you very much!!
Perfect job, from Cambodia🇰🇭
Thank you very much sir God bless.
What topology use in laptop chargers?
Thank you for the informative videos
Best regards ☕☕
Perfect job.Thank you
thanks a lot
Good 👍.Assalaamu alaikkum Please do a video on how to check leadacid battery condition through multimeter & by using hydrometer.
awesome ! from Bangladesh.
Supper....Danke
very important thanks
Most welcome
Well done Sir. Same adapter , the signal wire shows disconnected. If it’s available to purchase from market? I think it’s feed back cable.
Please share circuit analysis of ut mig 400 welding machine circuit board
I have enjoyed it.
Peace be upon you. How can the resistance of the RGon base be calculated when designing the Geat Driver?
Thank you 🌹
Very ironic that I’m dealing with the same power supply at home. My question is I have 19v at the connector when the psu is connected, when I plug it to the AIO HP computer the psu shorts out from possible overcurrent or some type of protection . Once I unplug it and plug it back the voltage comeback. Is it the power supply shutting off from the draw or does the computer have a fault that send a signal to shut down ac coming in?
Sounds like a short on the motherboard is causing the charger's protection circuitry to trip and shut down power.
👍
hello sir ,i want know where can i buy sucker bouth that you are useing one.
Emeğine sağlık Eşref hocam. Bu adaptör de pfc devresi varmı.Teşekkürler. Allah CC sizden razı olur. İnşallah.
WE ARE REALLY ENJOY UR VIDEO, PLS KEEP IT UP.
SIR, WHAT IS THE NAME OF MICROSCOPE CAMERA U ARE USING. THANKS
it is my pleasure

Same charger I repaired 4days before sir. The line filter coil of neutral is damaged In my charger. So I made a jumper and done a job. Because I don't have any scrab pcb.

Haseeb, I am a total novice trying to learn from the best,here is my question: , we have 3 parts that failed, a fuse , capacitor, rectifier, , in your opinion what failed first?. I'm just curious what caused the capacitor to fail ? thank you for sharing your thoughts.
most welcome dear
the first failure root cause is capacitor
when capacitor's di-electric fails, it creats short circuit between its +ve and -ve plates. that creats over current condition in dc rail, thus bridge rectifier and fuse failed
@@HaseebElectronics Excellent reply, I do understand the logic behind it, thank you Haseeb.
