Lenovo Legion 5 Pro 16ACH6H Water Damage

[Andreasbest]

Hello!
Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
Is this normal?
Thanks in advance!

I've been tinkering on Acer A715-43g that had boot issues. Voltage rails are present and keyboard LED lights turns on when power is pressed, but black screen and will not continue to BIOS, I also tried connecting to external diaplay and no activity either. I need to do power cycle at least 10 times to boot the laptop and OS will load. I already changed RAM, CMOS battery and SSD. Can you suggest something I need to look or test next?

Hello, I hope you are doing well,
I have a Dell Optiplex 7010, board number: OGXM1W.
Everything works fine, but there is no processor voltage. After looking it up, I've found that the L115 IC takes 12V, but there is no output on any of its pins. I searched online and couldn't find it either. I have old computer motherboards with the same IC but with different numbers and locations. Can I replace it with any IC or not? If not, is there another solution?

Thank you....

Trying to learn electronics repair as a hobby. I have no formal training in electronics, circuits, etc. Everything I know, which isn't much, has been learned from watching youtube videos, reading books, forums, etc. This means, sometimes I have a hard time understanding and interpreting what's important when I look at datasheets, and such.

My brother has a TV that I'm working on now. He said he was watching it, he heard a loud pop and it went off. I used my DMM to check the fuse, it was blown. From watching lots of hours of electronics repairs on youtube, I figured that was just a...

Hi everyone,

I have an IdeaPad 1 14ALC7 Laptop -

Type 82R3

There is an EXE file and I cannot seem to spot the raw bin file anywhere within it. Is there anywhere I can get the raw in file or what is the next step I should take?

That's now the second time in my repair career that a through hole resistor go short!
it was a Vishay CPF124K900FHB14 1W resistor measuring new 24.9kohm. <- notice the KILO ohm. Well now it measures 28.1 Ohm! See picture and PDF attached. This is something very rare happening, but apparently it does happen!...
