Here we will give just a few pointers to what kind of troubleshooting has to be done if you suspect a board issue.

Powers on but no display

• Check if it's no backlight, no image or both
  • If no image:
    • Check if external display works, try with internal LCD disconnected as well.
    • Measure voltage on LCD power rail(s)
  • If no backlight but image is present
    • Try to locate the fuse (or resistor or inductor) to backlight rail and check if it's blown
    • Measure voltage on backlight rail, backlight enable signal, brightness adjustment signal
• Check if laptop is POSTing: pressing caps lock key triggers caps lock LED, activity of USB drive blinks when turning on, audio plays, HDD is being read, etc… If it's not POSTing:
  • Check RAM compatibility
  • Reseat RAM and clean RAM slots
  • Measure exact voltage on CPU VCore
  • Check CPU Reset signal
  • Follow power sequence if it exists in the schematics
  • Follow list of power rails if it exists in the schematics

No power

• Check Laptop battery charging circuit
• Check if DC-in jack LED lights up
• Check voltage on all the large inductors
• Follow power sequence if it exists in the schematics
• Follow list of power rails if it exists in the schematics

Note: don't forget to trigger power button when measuring for the rails that only come up when machine is turned on.

When requesting help, please attach a picture of the board with voltage and resistance to ground measurements on all the large inductors after triggering power button.

Powers on, display ok but something is wrong afterwards

• Exclude software issue by booting from another drive with Windows 10/Linux/macOS
