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.
it is my pleasure it is ANDONSTAR AD407 Pro it is fantastic microscope with HDMI output to connect external TV 7 inch screen and FHD video with amazing frame rate selections
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
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?
Another great repair by the PS master! I don't understand why all the silicon - some PSs have it & some don't.

I really like the work you do on the electronic plates with the microscope. I am enraptured.Keep it up.. thank you very much!!
I've learned so much from you please keep on teaching us
Perfect job, from Cambodia🇰🇭
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.
Excellent thanks for sharing this informative video keep sharing❤❤❤
it is my pleasure
Another great video. I learn so much from you.
Thank you Kimbo
What topology use in laptop chargers?
Thank you for the informative videos
Best regards ☕☕
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
it is ANDONSTAR AD407 Pro
it is fantastic microscope with HDMI output to connect external TV
7 inch screen and FHD video with amazing frame rate selections
@@HaseebElectronics thanks my boss
Very informative content. Shukriya Maestro
thanks a lot for your valuable words. have a great weakend
@@HaseebElectronics you do the same !!

Good 👍.Assalaamu alaikkum Please do a video on how to check leadacid battery condition through multimeter & by using hydrometer.
Emeğine sağlık Eşref hocam. Bu adaptör de pfc devresi varmı.Teşekkürler. Allah CC sizden razı olur. İnşallah.
Perfect job.Thank you
thanks a lot

@@HaseebElectronics Excellent reply, I do understand the logic behind it, thank you Haseeb.

Sounds like a short on the motherboard is causing the charger's protection circuitry to trip and shut down power.
Excellent demonstration brother, keep up the hard work.
awesome ! from Bangladesh.
Friend... What did y0u used f0r cleaning after s0ldering?
Please share circuit analysis of ut mig 400 welding machine circuit board
Peace be upon you. How can the resistance of the RGon base be calculated when designing the Geat Driver?
Great repair! Thanks and take care!
best regards
Excellent sir! Thanks for sharing!
it is my pleasure
Thank you very much sir God bless.
hello sir ,i want know where can i buy sucker bouth that you are useing one.
Supper....Danke
