This is OK: a shorted mosfet. The problem is when the 2 mosfets are fine. You must suspect about the IC charging pump, which manages the mosfets' gate.

IF you did not have a donor mosfet, in this case since they are the same and only the 1st mosfet is broken, you could have switched the 1st MOSFET with the 2nd MOSFET and THEN jumped the 2nd mosfet with a wire. Then the charging chip should be safe. Of course, replacing the mosfet with a new one is always better but if you are in an emergency, this could have worked too.

I've been working on Toshiba l850 boards recently. One I jumped eventually failed. There was hole in charge ic. I think you are right. Best not jump. Another can't get powering. Seems like signalling from EC to charge ic bad. Anyway I'll play until it's fixed or I die.

I just tested some power banks, how to make them stronger, and what to do to reach their max output power. The solution is simple, connecting a 4.5V soldering iron to the USB port and use it for testing bad boards. Some get stronger in 2 minutes, some need 10 minutes to reach max power (older devices).

Hi great video, can you do a video on how to replace a mosfet by reading the lettering on the mosfet, as I agree with replacing it but how you read the letters on the mosfet and if you can't get how too find the one you can use, your very good at what you do👍😁

Pls sir… what are criterias for changing the first mosfet? Must it be from the same type of laptop/motherboard? Or any mosfet with same number? Or just change from anywhere? Or can u replace N channel with any N channel and P channel mosfet with any P channel mosfet even if is not the same number? 🙏 pls help me

I understand but I used to bypass two mosfets and it charges , can you explain please ? I know in newer laptop the BQ chip won't allow that but how about older laptops ? I tried it myself in hp pro book board which first two mosfets was burned and welded to the board and I bypassed them with jumber wire and laptop was working and charging

If a mosfets number ends in an even number its an n channel and if it ends with an odd number its a p channel mosfet thats what i learned to do
@hardkore360
@hardkore360 2 года назад
that's not always the case, I have a 18537 mosfet from Texas Instruments and it's an N-channel mosfet, so always check the datasheet or test the chip.

I often wonder how a screen gets scratched when repairing the circuit board and now I know, people like you sliding the board on it like it's a work bench and when they ask you how come it's scratched you tell them it wasn't you you were working on the circuit board, really bad abuse of a customers property, very very unprofessional.
