Good luck

Ok sir , nicely explained. I have a question . Which pins out of 8 should we short in order to reset the BIOS. I know that CMOS jumper can do this but in my case that jumper is useless as well as the button battery. I need an alternative way to reset the BIOS. I can't boot the PC as the internal GPU is disabled in BIOS setting. Motherboard is zebronics h61.

[@electronicsrepairbasics_erb]

Depanding on type of the computer you have. you can use Use the multimeter to check between the jumper and the bios and you will find the right pins. the multimeter should be on the continuity option.
Good luck

[@busybusiness9121]

@@electronicsrepairbasics_erb , sir , the my CMOS jumper section is having 1 capacitor and 3 resistors.
The central ( 2nd pin) CMOS pin supply is going to the capacitor and then to the 20 kilo ohms resistor and then I'm unable to trace it.
The last CMOS pin ( 3rd pin ) is going to the 4.7 kilo ohms resistor and then going to 4th pin of BIOS chip ( i.e ground).
The first pin of CMOS is going to the 20 kilo ohms resistor and then I'm unable to trace it.
Please help me sir.

Greetings ! please make a tutorial video about what is "main power rail " on the laptop mainboard. thnx

[@electronicsrepairbasics_erb]

Noted, Ok I will

[@Martin-ot7xj]

Hi, i have a question at 09:05 , you explained that pin number 4 is connected to the ground, and we must set the multimeter into continuity mode, my question is continuity mode means they are connected to which other? right ? thnx

[@electronicsrepairbasics_erb]

Right Martin

[@user-de8oj7vk3f]

Excuse me sir, I have a device (All in One) that does not work despite the presence of power in the motherboard, as if the device was dead. What's the solution?

[@fazlhaq4477]

Hi can u make you web more professional for example 30mint videos gave use trailer 1mint then we think we can pay it’s worth

[@blackimp4987]

I like the care you have in assuring that your viewers have really understood what you are teaching. thank you. one request: it would be interesting a similar explanation of the chip that allows the first mos after power plug to stay open and let che current flow to the second mos in the power stage.

[@electronicsrepairbasics_erb]

Thank you so much
