Hi,
I have a Razer Blade Base (2020) notebook with 2 missing MOSFET's. The motherboard marking is DA550-MB MP V4.0. There are no schematics or boardviews available.
I have marked the missing components on the attached screenshot. If anybody has a similar or identical motherboard, please do tell me the part numbers.
Thank you very much in advance!
Cheers,

Hi everyone,
I recently acquired this card from a seller who was selling a PowerMac G5 for parts. He mentioned that the video card was probably broken too.
Upon closer inspection, I can tell the reason why it won't work: it's missing a bunch of CAPS! (it's also missing an inductor - 1.0uH).
It's a nice card as it's one of the few AGP cards that will support 2560 x 1600 resolution on a PowerMac G5 using a 30" Cinema Display.
Looking at the card, it appears to be missing the following:
1x 1.0uH inductor - orange square
2x... -
Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and...08-19-2024, 05:22 PM -
Hello. I would need some advice please.
My son's MBP suddenly stopped working and is now only getting the green-then-orange light on Magsafe and no fan spin.
He brought the MBP into the house (22 deg C) from a very cold conservatory (-3 deg C) and turned it on straight away. The Mac suddenly died a few minutes later.
I examined the logic board and couldn't find any signs of water damage, corrosion, blown up components etc. Nothing was ever spilt on it, and the logic board looks immaculate.
I have already replaced the logic board with another... -
I bought a use Intel I9-12900KF CPU and i received it damaged. But it looks like only one component one the backside is missing. But the solder pads looks fine.
I already "googled" it and compare the backside picture of other LGA1700 12th Gen CPU. They look all the same, no matter if its an I9 or an I3, even the Pentium. And at that spot should be a capacitor.
Does anyone have a schematics or assembly diagramm of the alder-lake cpu-backside? Or just know what size and value i need to replace the missing capacitator.08-06-2025, 01:36 AM
