Lenovo Legion 5 (Model: 15ITH6H & Type: 82JH) - Schematic Diagrams & BoardViewFiles Needed

UPDATE:
Damn...this is going to take a lot more time than originally thought...
When i started the repair of the device, i hadn't yet bought a stereo microscope...so i just checked the board a second time visually with the microscope...and i have to say: i'm shocked! not only that the test points are already starting to oxidize...most of the components as well as some vias are in a similarly poor condition...
Fun fact: I found an old Robotron personal computer (made in the GDR in the 80s) in our garage and completely restored it... and guess what? Although... -
Yay! Thank you very, very, very mutch!!!
Now that I'm finally done cataloging the defective and corroded components of a Lenovo TP480, I can spend the next few days calmly dealing with the QSC amplifier...
As soon as I've identified the fault there, I'll be happy to let you know...Leave a comment:

Search for: QSC K10.2 Circuit Diagram & Component Layout Overview
Hello everyone! :-)
An acquaintance of mine works as a DJ in his spare time and brought me a defective [U][B]QSC [/B][/U]active loudspeaker ([U][B]Model:[/B] [B]K10.2[/B][/U]) for repair.
Error description: The device could not be switched on (after he lent it to another DJ).
A visual inspection revealed an obviously blown fuse (F41) and a cracked thermistor (R41) on the mains filter board. A closer look at the amplifier board revealed two defective power MOSFETS (Q13, Q14) and other defective components on the +12VLOW rail.

Searched For: Intel DQ77KB - Circuit Diagram (And If Possible Also The Component Layout)
Hello everyone! :-)
A friend of mine asked me if I could repair his parents' defective PC...
Therefore, I need the circuit diagram (and if possible also the component layout) of an Intel DQ77KB mainboard.
Can anyone help me with this, by any chance?
Thanks in advance!

Hello everyone! :-)
I am a sticky something from beautiful Germany.
I ended up here because through my volunteer work, I often have to deal with defective laptops and desktop PCs where the fault is (too) often due to a defective mainboard... :*-(
