honestly I do the same steps for three different laptop chargers but I discovered that the volts under 8 volt not stable and can't operate or work any load its like pulses volt useless , not stable > in other side the volts up to 12 volt is good until 30 volt .
the companies of electronics know that tl431 has range up and down 10 volts from the basically its product volt ( 10 v----- < charger volt > ------- 10 v ) . i suggest to try this modification with charger 9 volt 2A it will work successfully 100% . depend me
Amazing. Good work 👌👍

@@ahmedsoffy581 same. My adapter is turning off automatically. And it worked 3.5 to 20 volt. But voltage was very unstable.
Is it 330 ohms resistor or 33 ohms resistor?
330 ohm

Are voltages stable on constant load of motor ?
@@drsajjadashraf...9291 yes
Why you solder third pin of potentiometer?
@@MACYNET323 its like u connected + with - suing resistor for stability maybe
Mers charger me tl431 nahin hai to kya karu
TL431 Nahi hai to us ki jaga kia hai?
Sir please tell me tl431 ki jagah pe our Kya Kiya ho sakte hai
TL 431.
