Sir..dell inspiron 15 3521..no display with 7 low beeps just like a knock sound..pls advise

[@mandarpatil9434]

Sir, plz tell me what is the cost of this work you took from customer.

[@YamiMTA]

Hello!
I would like to ask you the following.
I have the same problem as the video, after checking and see that I have the same results as you, remove the transistor and instead of 15v I have 10v, I still do not put a new transistor so I do not know the result. I would like to know some recommendations. Thanks and very good work!

[@Laptop_repair_zone]

You can replace a new N-channel mosfet or you can short with jumper wire.thanks.

[@YamiMTA]

@@Laptop_repair_zone I have turned to you again. After changing the UZ1 and effectively, it gives me current in the indicated terminals, which did not happen before. However, instead of giving me +15 volts like at 5:25, it gives me 9-10 Volts, and the error persists. In the + VCC_CORE (6:05) does not give me any voltage, it stays at 0. Do you think you could give me some indication of what else to check or review ?. Greetings and good work.

VERY GOOD. RESPECT

Thanks so much brother.

Every desktop, laptop motherboard has this 8 feet thing that looks like switching mosfet. Even graphics card board has it. Can I just get one from a motherboard and place on my Dell motherboard? Will it work?

[@Laptop_repair_zone]

Just replace a N-channel MOSFET thanks.

[@panjipanji4012]

My laptop, firstly 5 beeps and no screen display. And one day, i cleaned RAM. Than I turn on my laptop give me 7 beeps and no screen display. I try turn on and than off about 5 times.
My laptop was succesfully boot without beeps sound
