I have a 820-2915-B board that gets in S0 state, but no image, chime, backlight and CPU activity (checked with USB stick with LED). Fans do spin (first 3 seconds on, then 3 seconds off, then stays on). Heat sink gets warm (not hot). No visible damage on the board. S0 rails like PP5V_S0 and...

This 820-3662-A board has a pulsing PM_SLP_S4_L. S5 rails are stable. Checked around the U6100, but no visible damage. Termination resistors are good. Currently I don't have a donor board for this, so can't replace U6100 to test. Any other things I could measure or try before buying a donor board?

I have trouble finding the short on a 820-2879-B board. Resistance to ground on PPBUS_G3H is 11 ohm. I removed F7040, short is on the side of pin 2. A bit of (sugar-ish) liquid damage on U7500, C6960 and around R7400. Cleaned with IPA, but 11 ohm short remains. Have put 0.8V directly on...

This 820-3332-A board runs fine with the charger connected, but won't run on battery. When it's booted the OS sees the battery (says 17% charged), but won't charge the battery. There was liquid damage around the battery connector. When the system boots there is 12.5V on J6950 (PPVBAT_G3H_CONN...

I have a 820-3787 board that doesn't display any image, also no backlight activation for that matter. Someone unskilled has clearly messed with this before, since one of connectors on the wifi module has been ripped off, some of those pogo-pins for connection to the bottom plate have been...

I have a 820-00923-A board that gets into a S0 state, but no fan spin or image. Since I can't find the correct schematic and brd I'm using the 820-00239 one, seems to work ok with this board. The board takes about 0.77A and CPU is getting hot, so seems to boot. I'm not getting All_SYS_PWRGD...

I have a 820-2936-B board which was completely dead. There was a short on PP3V42_G3H, which was a short internally in the ISL. Replaced the ISL and the system booted. But now it doesn't run on battery, and the system doesn't recognized a battery. The battery that was present was at 0V, so...

I have a 820-2850 board that doesn't display an image (checked with a flashlight from the back). Backlight also doesn't work. There was liquid damage on the LCD connector, replaced connector, but still no image. Currently don't have a mini-displayport convertor, so can't check image externally...
