Measure the voltage on the DC power jack's pins. You should read approximately 19V when the laptop is plugged in.

You're looking for a proper guide on the ASL50 LAC921P Rev 10 schematic. Here are some steps to help you:

If you’re repairing a device containing this board—perhaps an LG TV that won’t power on, has no backlight, or shows intermittent behavior—a schematic diagram is invaluable. It shows voltage rails, component values, test points, and signal paths. asl50 lac921p rev 10 schematic free

Ensure the SPI Flash chip has 3.3V on Pin 8 and data activity on Pin 1.

Once the power button is pressed, the EC sends wake signals to turn on the rest of the operational power supplies: +1.35V (DDR3L) or +1.2V (DDR4). Measure the voltage on the DC power jack's pins

Use the search function ( Ctrl + F ) in your PDF reader to look up specific component designators printed on the motherboard silkscreen (e.g., searching "PU301" will instantly jump to the power management IC schematic section). 5. Step-by-Step Troubleshooting Checklist

According to technical overviews, this revision typically includes: : Intel Skylake-H (SKL-H). Here are some steps to help you: If

: If you need the matching BIOS file to go with your hardware repair, sites like WitComputers list the specific Rev 1.0 BIN files for the ASL50 LA-C921P.

Using the boardview file to understand component locations, visually scan the board for any signs of physical damage, burnt areas, or corrosion.

Before the laptop can boot, it must generate the standby voltages. The 3.3V_ALW and 5V_ALW rails power the Super I/O controller and the power button circuit.

Once you obtain the schematic, here are some general steps to help you understand it:
