💥 My best wishes to ARNAB Dhar

Good morning ,ustaad n my friends

Vo 12 din jindagi k aise beet gaye

Jaise hath se rait fisalti hai.....

Ustaad ka apnapan .........


Naye dosto ka bhai jaisa pyar


Ustaad aur ustaad ki lab.......

Vo pyaar bhari maar aur ustaad ka dular(pyar)

Kuchhh naya sikhana.......

Aur raato ko jagana......

Milkar khana aur milakar kaam sambhalana..........

Subah der se jagana........

Ustaad ka maa ki tarah care karna......

Repairing ka new knowledge.....

Ye sab jinadagi mai nahi bhool paunga......
Wapas college aur study ke din aa gaye the.......

Har din har raat har pal.....
Ustaad ke sath bahut kuchh sikha ............

Na keval laptop repairing ....
Sath mai jindagi ko naye tarike se
Jina sikha.......

Shayad ye meri jindagi ka turning point hai........

Ustaad k sikhaye knowledge aur hunar se pakka ab kuchh badal raha hai aisa lag raha hai......

Sabhi dosto ko aur mere loving ustaad ko shukriya.....Vo sab kuchh jo 12 din mai diya uske liye ,ek baar phir se shukriya.........
Miss u all😍😍😍😍
Didi n ammi ka bhi bahut bahut shukriya

Case study#01
HP Pavilion G4(R23)
>Open the laptop and removed dust and corrosion.
>Checked all coils and bios impedence, all are good..
>Now connected the DC Jack, ampere goes to 0.071..
> I found S.B IC is heating...
>But i didn't removed the IC, checked the impedence at all of it's pin..
>Got impendece value.
>Now I move on to checking the voltage requirements..
> Firstly I checked the VIN supply to the IC, but i didn't got VIN on respective pin of the IC..
>Now I opened the schematics, found that at one end of resistor 19v present but on other end only 2.5v there, so i replaced the resistor from scrap board..
>After replacing resistor, again I connected a DC jack, now SB IC is not heating and ampere is showing 0.025 ..
>Now I triggered the board, ampere rised to 0.650,..but no display😭
> Now I done the Bios, changed the ram, cleaned the ram slot, washed the board and put in owen etc... But again no results 😔.
> Now randomly found one IC PU12 just below the ram slot..
>That IC is getting all inputs and enable, but not releasing output, that should be around 2.5v as per schematics,..
>Now I changed the IC from scrap board with correct number, luckily I got the same IC..
Now again I connected DC jack, triggered the board now ampere rised the 1.300 and came back to 0.956, ..
>😀got the Display....
