ASUS X553MA - No power and no lights after hard reset and battery disconnect
I have an ASUS X553M laptop that will not power on and shows no indicator lights (power or charging) when plugged in.
I have already tried the following troubleshooting steps:
- Verified the AC adapter and wall outlet are working.
- Opened the laptop and performed a hard reset by disconnecting the internal battery and holding the power button for 60 seconds.
- Attempted to power on the device with only the AC adapter connected (battery removed), but still no lights or fan activity.
- Inspected and re-seated the keyboard/power button ribbon cable to the motherboard.
- Checked the DC power jack, which appears to be physically intact.
Since there are no signs of life even with the battery bypassed, I suspect a motherboard-level power delivery issue. Are there specific MOSFETs, fuses, or capacitors on this board known to fail that I should check with a multimeter?
Ist dies eine gute Frage?
