Hello again,
got an MacBook Pro from 2015, model A1502 and motherboard version 820-3476-A.
Device died over night on charger.
Currently I did the follow things:
1. Checked visuell the board, test with another MagSafe-Charger and with another DC-IN-board too
2. Measured 16,5V on PP18V5_DCIN_FUSE but 0V on ADAPTER_SENSE and 0V on PP_3V42_G3H and 0V on PPBUS_G3H but 16,5V goes to U7090
3. Because of corrosion and bad resistor values I changed these components: U7090 / C7094 / C7095 / R7095 / R7096 / L7095 / C7099 -> But further... -

Hello there. I've got an issue with my Macbook Pro A1425 820-3462 with no green/orange light when plug in. Also I was unable to boot with the battery plugged in. When I change the DC-in board to another spare one I had, it show orange light and boot up with fan spinning, without the battery plug in. But it will randomly just not showing the magsafe light and the system become slow and the fans just when erratic all of sudden
Here's the voltage I've measured based on the guide I've read :
Original DC-in board (no green/orange light, no fan spin) :

Hello Everyone!
I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died....06-28-2025, 02:57 PM
