Hello everyone,

Trying to identify the following part J7 FL M1R in the photo which is on one of the power circuits on a Dell 15-3537 motherboard. Went through the SMD code manual but couldn't find it and google doesn't either.

Help please and thank you

Working on a motherboard that starts up (fan turns on) but don't get a POST. It's for a multi-game arcade cocktail setup and would like to identify the motherboard (see picture below). Here's the information I've gleamed so far:
AWARD BIOS PCI/PNP 2018 268436163
Chip Set: SiS 651
Southbridge: Sis 962L
CPU: Intel Pentium 4 2.406hz/512/533 sl6rz (socket: 478)
Dimensions: 190mm x 245mm

I’m trying to fix a Corsair mechanical keyboard but could someone tell me what the circled part is as I think it may be the issue. There is 2 legs with a small square seethrough piece at the top that is separated inside almost like a fuse but it’s labeled d140 which I assume is some type of diode?. I tried searching but couldn’t find any part that looks like this....

Hello,

I received an HP Omen b550 motherboard from prebuit PC that won't boot. It might only support Ryzen 5000 series processors, which I don't want to install until I resolve one issue.

The motherboard draws 350mA at idle and after switching on (using Ryzen 2700) it draws 1.6A without any fluctuations and nothing happens, no POST and no beeps. None of the main power lines indicate a short circuit.
The thermal imaging camera shows a 2R2 resistor getting hot, connected to one of the pins of the chip. I can't find it online to order one or a replacement if necessary....
