Thanks man

[@electronicsrepairbasics_erb]

You're welcome!

[@johngape12-5]

thank you a lot! but i am confused: in your videos talking about 5V and 3V it seems like they are generated by the single IC, but in this block diagram i saw 2 different IC one for 5v and another for 3v, plz correct me if 5v and 3v are generated by the same IC or if it depends on motherboard.

Hello, how desktop PCs motherboards are different from laptops in terms of power rails/voltages?

[@electronicsrepairbasics_erb]

There are some differences but not much. I will explain the desktop motherboard soon

[@asv5769]

@@electronicsrepairbasics_erb Thank you. That would be very interesting. Desktop motherboards are often neglected when it comes to electronics repair. I would like to learn whether desktop MBs are simpler or more complicated than laptops.

Hey there, I follow your videos daily. I have big issiue that I can't solve for already 5days. My Lenovo t410, is getting 19v. I have tested the IC u41 controlling the 3v and 5v MOSFETs. On the reference pin 22 I am getting 3v but on the pin 29 I am not getting reference voltage 5v. Could you please look on the schematics and maybe you can give me an idea what else to try? Also there are other 2 ics u42 and u 23 and I am not sure which one of those is the kbc chip. I don't necessarily need this laptop, but I don't wanna give up on solving the issue, I am using it to learn. I have idea the u41 is faulty but I am really not sure
Ps. I have tested all capacitors and indicators for short, and there was no short to the ground

Here is the challenge;
Buying a backlit keyboard (with 2 pin extra power flex) for a replacement when there is no backlit power pin on the mobo.
Need suggestions from pros!

[@orfe]

I mean finding correct power (assuming 9/12V DC) to keyboard backlit pins all i need.
(ps. i have and old little analog multimeter)

[@electronicsrepairbasics_erb]

I didn't understand you bro
