zenbook flip 14 (UX461F) -- not powering on + charger lights up power light instead of charger light

[cosmicblade]

It had been charging just fine previously. I could plug it in, juice up, and then use it unplugged for hours.

 

Then last week I was using it unplugged and the battery died -- not unusual and has never caused a long term issue before. I fetched the adapter and when I plugged it in the current problem began.

 

On the UX461F, there's an indicator light for when you charge it. This has always functioned properly in the past. There's also an indicator light for when you turn power on; this light stays on as long as the device is powered on. 

 

The new behavior is as follows:

• While unplugged, no lights or power at all
• While plugged in, power light turns on inside of battery light. I am also extremely confident it's not powering on. Not only is the display dead, but the UX461F is both loud and hot when it runs (this laptop has notoriety for getting hot)

 

The behavior SHOULD be:

• plugging it in causes the battery light to light up
• power light only turns on if you power it on (it should not be triggered by the charger afaik)

 

The following DID NOT WORK:

• Holding down power for 10, 20, 60, 90 or however the hell many seconds different troubleshooting guides say
• leaving it plugged in for multiple days and "waiting it out"
• popping the battery
• combinations of battery pop/power hold down that are supposed to "reset power management"

 

Is there anything else I can try? I have a hard time believing it just bricked; it was running perfectly fine seconds before this started happening. No slowdowns or anything. It wasn't even hot like it often is. It was having a good day if anything. I also struggle to believe it could be the battery when it still had had high survival recently.
