Troubleshooting a Laptop Power Issue
I own an ASUS laptop with detailed System Specs.
Recently, an issue has emerged whenever the power adapter is connected. An alternating message of "Plugged In" and "On Battery" continuously appears on the screen, disrupting other activities. At times, this cycling stops after a few minutes, but often persists until I disconnect the power adapter. I've noticed that moving the laptop while plugged in can trigger this behavior.
Even when the laptop is turned off with the power adapter attached, I observe the charge light flashing on and off continuously. Typically, the charge light should remain steady when the battery is being charged and turned off when it's not. Despite conducting online searches and attempting suggested fixes, nothing has resolved the issue. I came across a few individuals facing the same problem, with one person trying to remedy it by replacing both the power adapter and battery, without success.
Consequently, I suspect there might be an internal fault within the laptop, possibly related to a faulty power connector or charge circuit. As my warranty expires on October 10, I'm contemplating my next steps. As a precaution, I've replaced the 1TB Samsung SSDs with the original 512GB Intel SSD in preparation for the potential need to RMA the device next week.
I'm hoping to avoid this scenario, so any advice on potential solutions before the warranty expires would be highly valued.

I've analyzed the situation you described, and I want to be direct with you: your diagnosis is almost certainly correct. The evidence you've gathered—especially the charge light flashing even when the laptop is powered off and the way movement triggers the issue—points strongly to a hardware fault, not a software problem.
Since you've already swapped the SSDs, you're ahead of the game. Before sending it in, do a final check to remove any personal data and ensure the original hardware (the 512GB Intel SSD) is installed.
Ensure your BIOS, chipset, and power management drivers are up to date from the manufacturer’s website.
Take it to an authorized service center for a hardware inspection, focusing on the power connector and the motherboard's charging circuitry.
