Case study
Cedar-13269
Prb- battery 🔋 mode on
Adaptor mode off
1 cheq cheq CLR
Vin not pass
Then go to first MOSFET gate 20v(this is p ch MOSFET) Remove and cheq MOSFET is ok
Cheq gate back trace
Voltage divider not working
But register are ok
Next go PQ4205 this is  not 🚫 working so just remove and
Cheq gate it's 3.2v put the MOSFET
💥 Boom vin pass
Board on with adapter charging ok 🙏 thanks guruji for sochne ka tarika shikane ke liye

Case Study-47
La-6562p
Problem -Dead
Dc Reading 0.004
Open laptop and Check someone already worked on bios and charging section
First i check all coil impadance all are ok
Then check charging section
Pq4 was Short its p channel MOSFET replace it
Now Dc Reading is 0.012-40 fluctuating and PQ4 MOSFET gate is High Low High not Stable
Backtrace SOFT_START_GC its come from PU14 CD3301 not available in my collection
So i bypass this ic Using AFS Rehber Data
When i By-pass ic Now Gate voltage is Stable and Dc Reading is 0.011
Trigger the board Board is Working and Give the Display but
Problem No 2
Battery 🔋 not Charging Adaptor shows Unknown
Check PSID found
PQ2 and PQ3 was Burn so I Replace it but same then i found PR9 was Open Replace it Done adaptor showing 90W and Now battery also Charging
Thanks to Md. Rafi Sir For this confidence and and your Motivational Teaching
Thanks AFS Solution ❤️
