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.

Please help do a video tutorial on audio system in laptops and all components involved. Thanks

You found there was no 3.3vdc on the first board. Why not show how to isolate the problem and fix it?

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?

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?
