NZXT N7 Z370 knocked components
Hi there, if anyone could have a quick look I am missing 3 components on bottom side of PCH
Mobo does not post (reset pulled down, no vcore etc).
Thanks in advance

My Sparkle (SPI) PC power supply has broken. Originally, there was totally no power output. The 5V-standby was not there. I have replaced a few bulged capacitors but not helping.
I was trying to do more troubleshooting but burned more components. Some got burned so badly that the markings were gone. And also, the markings of a few transistors were gone because the component surface was worn out somehow.
If you happened to have disassembled the same PSU model, please help to provide the markings of some of these components.
See the attached two pictures of the small...09-18-2024, 08:29 AM -
Hello, just wondering if anyone has the same board to help or have a schematic/boardview so I could restore its VRM circuit, a lot of knocked off components here on bottom side of the board and any mistake would probably burn either CPU or VRM circuit to ashes.
Mobo is Gigabyte B550 Gaming X V2 rev 1.1
Here are the pics and I did mark everything I am missing

Hi, Would appreciate some help.
I have an Apple Late 2013 15" A1398 MacBook Pro with Logic Board 820-3662.
Get charger light but no fan spin or chime. No liquid damage.
Found PPBUS and VCORE both shorted to ground. Other rails were ok.
Removed VCORE MOSFETS U7310, U7320 and U7330. Found U7330 was in fact shorted.
With the 3 MOSFETS removed, get PPBUS and fan spin. VCORE is still hard shorted to ground (0 ohms).
Attempted voltage insertion on VCORE to locate short using bench supply set at 1.0 VDC and 4.95 Amps (max current for my... -
Hi everyone
Here is the case that i'm trying to solve.
(short intro to explain what happened)
I bought second hand Surface Pro 4 and when I tried to reinstall the Windows it appeared there was the password on UEFI. Seller don't reply anymore. I decided to reflash the UEFI chip to remove the password. So I need to remove the chip from the motherboard first.
I have basic experience of repair tablets and phones, like battery or display change. So i opened the Surface Pro 4 and removed the motherboard successfully.

Hi, have a HP workstation Z2 Mini 4G for repair with CPU vcore missing.
The resistance at the output of CPU vcore coils, is less than one ohm so I think CPU could be damaged, but no mosfet are damaged.
It mounts an i7 8th gen, and have only i5 7th gen for test, but I think it is not compatible.
Without CPU in the socket there is no short, but there is no vcore voltag, and it emits a beep like no detecting ram.
The controller chip for cpu vcore is a MP2949A, and has no enable voltage at pin 37.
I wonder which circuit generates this enable...
