I learnt basic knowledge from an institute and from the basic knowledge I try to develop through various sources like books, Schematics, datasheets. I do have watched youtube videos even to get the knowledge. But my foundation is through the institute. If you firmly understand the timing sequence of voltages and signals that controls them, then laptop repair is very easy. I'm preparing a next video to explain the full timing sequence of a laptop came with water damage. Stay tunned !
@@philiptroniksmuch love from Nigeria keep it up man I learnt new ideas from this video you did now basically the ideas behind switching diode which means that whenever negative comes to the negative part of the diode it switches it
@@sendomc6427 Yes that is the basic function of Diode. You can understand the working principle of a diode in a bridge rectifier more clearly, which blocks and allow postive and negative voltages to convert to pure DC.
can you make a video from eg : 13 minutes how do we check the ite chip is the 19 volts charger connected where is the black prob of the multi meter at that time we just see the red one
@@KendraKelly-rp1gm No need to worry always one of the probe should be in the ground (screw hole) black or red doesn't matter in order to check resistance and voltage in SIO (ITE). For continuity check only you need to probe away from ground point to the intended place.
@@ugochukwunwamara4421 You can check with the help of schematics and with SIO pinout details. After ACOK is validated from charger IC either before or after pressing powerbutton S5_ON must be released.
nice work
Nice job brother, keep up up what you are doing 💪, i really like this kind of repairs
keep up good work ❤
Sensacional... excelente trabalho.
Very nice...keep it upp
thank you
Love from india
amazing!
Good job of explaining what you are checking, doing and why. Could I ask, where did you take your training for MB repairs and principles of operation?

Good day sir, please give me name of DC power supply in video.
@@tungnguyen6295 It is a normal regulated power supply YIHUA 3005D

Good day sir.. i want to know about the s5 signal. How can someone detect the s5 signal.
