    ACER A515-48m DA0ZA2MBAD0 request boardview or schematic

    I am looking for a board view and schematic for the Acer A515-48M laptop. The motherboard is DA0ZA2MBAD0 Rev: D.

    The motherboard was damaged by liquid spill, specifically in the area of the 3V power management IC. After cleaning all traces of liquid, I found a low resistance of 8 ohms on the 3V rail.

    I removed the Type-C charging controller due to overheating, and the resistance on the 3V rail increased to 430 ohms. However, this still seems too low.

          Acer TravelMate P214 - N19Q7 main power rail shorted to ground
          by mkdj
          Dear all,

          I have taken out the motherboard of a Acer TravelMate P214. There is a short to ground on the main power rail (19V). I don't have the schematics or boardview for this board (DAZ8IMB1AA0 REVA). But I have found 4 MOSFETS close to the main power rail : 2 N-Channel and 2 P-Channel.

          I have checked resistance across each of the 4 MOSFETS. I have the following readings:
          Both N-Channel Mosfets: nothing odd

          P-Channel MOSFET number 1:
          source - drain : 117 kOhm
          source - gate: 96 Ohm
          gate - drain: 117 kOhm

          P-Channel MOSFET...

          Acer x163w Monitor PSU schematic
          by atunguyd
          Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
          The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this...

          LA-N631P schematic and boardview request
          by reformatt
          This is from a 2024 Acer Aspire 15 N23C3. Unit has liquid damage but CPU seems to have survived. Can't find anything on this board, but have noted the following until a schematic becomes available.

          PUA01 RT6543AGQW (ML=) PCH +1V
          PUZ101 RT3624BE CPU Vcore

          PU301 RT6338BGQUF (RW=) +3.3V
          PU501 RT6310CGQUF (S2=) +5.1V
          PUM1 TPS51488 RAM +1.2V
          PUB1 Intersil 9238 B+

          UVH2 EM5109-A +3V LDO

          UK1 KB9542QG EC

          Main issues for this board are a hole in the PCH power IC PUA01. The hole is right on the L part...

          Lowest possible resistance on laptop motherboard rail - Guide Table request
          by Nagy Daniel
          Hi, I'm Daniel, and I'm new to the world of repairing motherboards.

          I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.

          I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.

          So, I generated a table with AI so I can...

          Acer A514-55-511P liquid damage
          by Kalman27
          Hello guys,

          I have an Acer A514-55-511P liquid damaged, and one component seems to have failed, but I can't figure out what this is.

          Thank you. ...
