@electronicsrepairbasics_erb I still can't believe in a three day dedication on your channel I can now understand the whole system schematic. Something I couldn't do after pursuing BIT for 4 yrs!!!

Hello. From Mar del Plata, Argentina. I want to tell you that this is actually a true Masterclass. Never so well explained in detail and with a great will to teach. I have seen many videos on various channels that have taught me a lot, but here I find everything in the process from when the signal is generated, where it passes and who receives it and why they receive it. A very, very good tutorial for beginners and some advanced users. Greetings.

[@electronicsrepairbasics_erb]

Thanks God, and Thank you very much. I'm 52 years old, for my lifetime I didn't come across a teacher like you. I pray for you and your prosperity. Sir I'm very sorry that not being a paid member of your channel. Sir I have problems in two old dell laptops. Battery is dead already. One of is, when power adapter connected the adapter goes off. No power seems to come to the laptop. Then I have to unplug the adapter from mains and put it again. And when again connected to the laptop power gets off on the adapter. Why The second is also a Dell Fan starts blue light on then Fan stops light is on, but nothing seems to be working. No display. Please give me a Clue how to solve these problems. May Allah almighty make your affairs easier.@@electronicsrepairbasics_erb

​@@electronicsrepairbasics_erb Sir the power supply without charging or how it works through 12 volts came from the baterry..? New subscriber sir .thanks...

[@electronicsrepairbasics_erb]

Thank you for subscribing and for your question. Laptops are designed to work with a range of voltages, and the internal power management system converts the 12V from the battery to the required voltages for different components. This ensures that even without direct charging, the laptop can function properly using the battery's power. If you have more questions, feel free to ask

[@celulartj]

The best I've seen ...... One question, how can the laptop work on 19v as well as 12v from battery being 7v of difference ? or in other words, why we have a 19v charger instead of a 12v charger if 12v is coming from the battery ?

[@electronicsrepairbasics_erb]

Very good question. Laptops often have built-in voltage regulators that can accept a range of input voltages. This means they can efficiently convert different input voltages, like 12V or 19V, to the necessary operating voltage required by the internal components. The power management system within the laptop ensures that it operates safely and effectively regardless of slight variations in input voltage. If you have more questions or need further clarification, feel free to ask. Thank you

[@DrSlouka]

Laptops typically use a 19V charger instead of a 12V charger due to the need for adequate voltage to charge lithium-ion batteries effectively. A standard lithium-ion cell has a nominal voltage of about 3.7V, so three in series (3S configuration) yield approximately 11.1V to 12.6V when fully charged. A 12V supply is insufficient for charging, as it doesn't account for voltage drops in the charging circuitry 1 .Using a 19V charger provides a necessary margin for the charging electronics, ensuring efficient operation and compatibility with various battery configurations
