The Asus ROG GL503V isn't charging or turning on.
Hello, I'm working on fixing my ASUS ROG laptop with the model "GL503V". It won't charge and won't power on either. The charging light stays off, and the indicator doesn’t illuminate. I confirmed the power cable is delivering 20v as expected. I removed the CMOS battery and held the power button, then swapped it out for a new one, but that didn’t resolve the issue. When I turned it on, a faint clicking sound was audible, so I investigated further. After disassembling the device, I found the noise coming from a specific spot. Could this be the source of the problem? Any advice or alternative steps would be appreciated. I’m new to laptop troubleshooting.
I faced an issue with a Lenovo Y580 after attempting to use Lenovo software for battery calibration. It turned out the Lenovo made shortcuts by removing components from the power circuitry during the process, which caused damage. The laptop became vulnerable to any electrical input, requiring replacement of several parts.
If it makes a click there's probably a short somewhere. I once fixed a laptop that had a shorted ceramic cap close to the RAM.
You might be mistaken about Asus keeping prices low for the components in their ROG products...
Testing with a thermal camera can help identify hot spots and eliminate a short circuit.
Couldn't anticipate such a rapid response. Probably switches on and shuts off in microseconds, with the sound of a brief surge in the VRM inductors during the click.
Inspect the capacitors on the board, focusing on the power circuit area.
Attempted it today, and you're correct. Unsure about the next steps.
