Brother, the charger of my Asus Tough gaming laptop is not generating voltage at the output
Resp Sir! Very నైస్ క్లాస్ Sir. -- ChinnaRao Paderu Andhrapradesh
i am getting 18v output which should be 19v acer laptop charger.indicator light on charger is ok..but laptop is not taking power..after long rest again charger works.. there is small burnt in circuirt board below main capacitor but not in any green part of PCB and any other components.
any solution?
Remove the capacitor and check if its weak due to short.. resolder all the points again..
Still I can't tell exactly what happened to your charger...
When I check my laptop adapter output is good but when I connect with my laptop that time charger is not accept lode
First check voltage on main filter capacitor if its okay.. voltage shouldn't be fluctuating a lot ...then see output caps, double diode rectifier etc..
Sarkat
ThankU. You are making this repair video correct.
1. Which component by appearance
2. It's name
3. Way to check their if damaged or faulty.
People are making so much cluttered video on this that my god... that not repairing the component seems better option.
Thanks man 👍
Amplifier se connect krte hi humming araha ha, baki sab thik ha, problem kaha ha batao, laptop ka adapter ha...!😊
Ground ka issue ho skta hai..... ground wire direct main capacitor k negative pe solder krdo.
@@Electricquantism402 ha ground ka issue tha thank u... Mere extension bord me earthing nehi tha, earthing ka connection krtehi humming zero.....
@@soumikmondal658 good.
Laptop charger ko plough me dalte hi house ki mcb trip ho rahi hai or house ki light off ho rahi hai kya fault hai ?
Reply ?
Power cable totally short hone ki wja se ho skta hai ye... Main cable change kr k check kro.
Cable ki shorting check kro multimeter se .
kash ap ka problem end tak huta hum aur b sekh lite sir
sir mera same yhi charger hi wo capicoter tak dc voltage btaa hai likin age auto coupler sb 0 voltage
sir ye full video bnain keh yhn kitne voltage ain ge capicitor se age mosfet auto coupler lines ic sab sir thnx
Thanks I enjoyed let me subscribe it was amazing ❤❤
Many Thanks 👍
I like your video.
How can I buy the transformer for the laptop adaptor? I want the name of the ferrite core, I mean the name and dimension .
I have searched online but I was unable to buy the ferrite core 19v transformer for laptop probably because I don't know the exact name to search in EBay or Aliexpress.
It's basically EMI section inductor you will get from old powersupply circuits.. while the transformer is not sold separately you have to replace from some other laptop adapter circuit.
@@Electricquantism402
Okay thank you.
I believe, it is possible to buy it somehow, maybe without the coil windings.
170w lenova adopter voltae 19.5 or 20 shows immediately drop 1.
Check the output caps... Check optocoupler also
Main capacitor may be faulty, 350v capacitor
If supply is ok but not charging what should I do ??
If its dell charger and output supply is ok but still not charging then maybe it's due to dallas 2501 transistor like memory chip which is connected on output terminals having three pins .
The power supply come from both neutral and positive of charger output when I check using Tester..how to repair it..Could you help me to fix this
Is it giving a shock or not from output?..
This happens when circuit is not grounded..
Check for it... otherwise it's fine.
@@Electricquantism402 @Electricquantism402 When I touch output pin It didn't give me a shock..When I used Tester it shows red indicator on both supplies (Both red and black wire)..But laptop didn't getting charge..how to check it is grounded or not..
@@Electricquantism402 Same condition but it giving shock what should I can do
@@sureshbalajijayakumar3814 check the output voltage..
@@rohitshinde6914 check the output voltage first..if its matches to the value mentioned on adapter so its fine..
For shocking problem, take a piece of wire and solder it between your input ground (3rd terminal in 220v plug) and output -ve wire..
Thank
sir I have a 19-volt 3amp laptop adopter my problem is when I give load on adopter voltage, it automatically gets 0 volts
There's should be some shortage
Does ac dc adapters contains mercury in it pls reply
Yes..in circuit boards and transformers etc.. they also contain lead and cadmium they all are heavy metals.
Is it danger
Ac adapter is teardown but it's working even though I am very tensed about the mercury
8 pin ic is dead, what can I do
Replace it. Find the number and order online.
Green indicator is on but not charging...
Output pin maybe faulty...check voltage on it and also on circuit output
My fuse was like... Go play. Don't bother me in talking. I am dead. I won't beep. Shoo shoo...go fatch. 😂
Hahh
My fuse is not working but when i direct ac current without fuse my wire gets broken so what to do next i hope u understand my English 😅
Urdu bol lo...
Konsi wire khraab ho rhi jb connect krte ho?..fuse wli jo direct ki hai?..
@@Electricquantism402 yes
@@singleplayer77 to iska mtlb koi aur chiz short hai... check mosfet or main capacitor
@@Electricquantism402 main capicator ko agar desolder kar deta hun to multimeter usse sahi dikhata Hain agar dobar connect kar ke check karta hun to continuously beep sound deta hai. Or MOSFET ka pta nahi ye kya hota hai
When I try to plug in my charger my inverter show short circuit and turn off itself
