@ernieschatz3783 3 месяца назад

I have seen zener diodes check good with a multimeter, but fail when you apply enough inverse voltage to put them into regulation. Same principle with a MOSFET...no continuity with a multimeter doesn't mean it will switch on when you apply the correct voltage to the gate...so I would't say no continuity while static doesn't mean it's "automatically good"

@Kane2009 3 месяца назад

Great tutorial as usual. One question please, from what I understand that it is normal to find components near the CPU giving positive continuity that goes away when we remove the CPU? Or this means that the CPU is faulty? Thanks.

@electronicsrepairbasics_erb 3 месяца назад

Correct, but the CPU is not faulty, it's inside resistance is low by default.

Thank you for a wonderful tutorial Sir. But sir I hav a dell latitude laptop and It popped a notification that my AC adapter is supplying less power hence will run its operations very slow. Which really happened. I checked voltage on my adapter and PC port it was oky 19.5v. what could be the problem Sir?

Hi, For 3.3 v. On BIOS, the power. Button should ve activated?

@electronicsrepairbasics_erb 3 месяца назад

No without pressing the power button

@ernieschatz3783 3 месяца назад

The MOSFET near the power jack had current flowing from the power jack to its drain then out of its source which is connected to the next MOSFET drain. Does that mean they are P-type MOSFETS?

@electronicsrepairbasics_erb 3 месяца назад

Right

My acer swift 3 laptop died. No power and is out of warranty. Only 2 years old. I rang Acer and it will cost me 210 AUD to replace the motherboard which is cheap . Motherboards on Aliexpress and eBay cost 400 plus.
