              Is VS_ON/RL_ON/M5V_ON signals present? Vcc to controller chip OK?

                      Acer Nitro 5 AN517-52-56A5 - won't charge, shorts the AC adapter
                      by gleniu
                      Hello,

                      I have a problem with Acer Nitro 5 AN517-52-56A5 (motherboard: GH51M LA-K862P Rev: 1A). I was playing TLoU2, which is a rather demanding game, for a few hours, unless the notebook turned off (my guess is that the battery drained to 0%). Now, when I connect the AC adapter, the LEDs are not coming on and the laptop doesn't charge.

                      It also shorts the AC adapter - I've checked two of them from different manufacturers. Though the AC adapter gives 19,5V as expected, the voltage drops to 0V when I connect it and disconnect from laptop - it comes back to 19,5V when I reset...

                      Apple MBP16" A2141 820-01700 PMIC power cycles no boot no shorts
                      by flusher
                      Bought myself a project thing. Apple MBP16" A2141 820-01700
                      No shorts, no visible waterdamage.
                      Dead. no history.
                      All USBC ports do 20V and charging battery.
                      If you plug battery/charger PPBUS is 12.6v and all power rails like RTC, 3v3, 5v etc are present. U7800 PMIC all voltages are present APART from PPVCCPRIMCORE_PRIM_REG (not sure if it has to be present at this stage?! resistance is 40 Ohm). SSD 2.5, 0.9, 1.8 are present on both wings. Charger meter shows 30ma or something like this on charged battery.
                      But what PMIC does is that it power cycles(dropping to...

                      ps5 2 second power on with fan spin, no shorts
                      by Thedan55
                      Hey everyone I'm totally lost!

                      the consoles power was pulled while gaming by customers wife.
                      I have a ps5 that's got blue light fan spin then powers off. About 2 seconds.
                      I have 12v, 3.3v, 1.8v 5v. From the power supply input prongs, that line of caps, I have 12v on the positive side.

                      I read no shorts anywhere on the board at all. I've injected voltage in 2spots following 2 videos from the cod3r and one other, I saw no current draw at all. i not very experienced with voltage injection so i only did what i saw online that was safe. ive attached pics of...

                      Nintendo Switch-No Shorts and not charging
                      by nebulink
                      This is a strange one for me. I have a Nintendo switch that turned on initially. The BQ chip was getting very hot. I unplugged and tried a different battery in case there was a problem with them one that came with it. I was told that the battery had been swapped.

                      After trying a new battery, the unit would not turn on.
                      Ammeter shows 15v 0 amp draw.
                      Tested around BG, P13 and M92. No shorts. Decided to swap out BG. Same result.
                      Checked voltages around BG, M92 and Max 177050.
                      Also checked Max 177621.
                      Getting desperate, I changed M92. Nothing
                      I changed...

                      by ziko07
                      Hi, I have this graphic card no image, when power on fans spin but I measured and has only +12v from PCI and power 12v both connectors. also +5v linear present, 3v3 from PCI present. MCU is cold, then I I tried measure again and on coils, 1.5V,1v0, 1.8v, on mcu 0.8v all present and mcu slictly warmed up. After that I tried to put on motherboard and still no image, but now also all those voiltages missing again , only +12v present and 5v
                      Then I measured (see image in red colour) and all those coisl has dead shorts, 0 ohm. I thing when first measuring voltage (I didnt check resistance) was...
