Hi everyone,
I am in the middle of repairing my Chuwi laptop motherboard that went dead after a power issue via the Type-C port.
After inspecting the board, I found a burnt DC-DC Buck Regulator IC on the back of the PCB. Unfortunately, the top marking on the chip is partially destroyed by the burn.
Motherboard Specs:
-
OEM/Board Code: Morshow J4125 (Intel Celeron J4125 / Gemini Lake Refresh)
-
PCB Markings:
2308 QL-M 94V-0 E328832/7NG089 J4125
Burnt Component Details:
-
Package Type: QFN-20 ($4\times4\text{ mm}$)
-
Visible Silk-screen Marking:
-
Line 1:
x715 -
Line 2:
D081(orD 081) -
Line 3:
AQ0L
-
Does anyone have the boardview/schematics for this Morshow J4125 board, or happen to know the exact Part Number (MPN) for this QFN-20 IC? Any equivalent replacement suggestions would be greatly appreciated!
(Attached are photos of the motherboard sticker and the burnt IC area)
Thanks in advance for any help!
