I have an ASUS K54C laptop, recently updated without issue to Windows 10.

I noticed recently - since the update but don't know if there is a connection - that the power button wasn't responding when I tried to use it to shut down. Instead, I relied on manual shutdown/restarts through the system menu, with no problem.

Last night, a program made the laptop extremely laggy and after several minutes during which I tried (unsuccessfully) to pull up the task manager to close programs, I tried the power button. When it did not work, I removed the charger cord and the battery (I was pretty frustrated). I then put the battery and cord back in but guess what, the power button isn't doing any more now than it was when the laptop was powered up.

I've tried all the tricks I've come across - removing both the cord and battery and pressing the power button for 45-60 seconds, left both unconnected overnight and tried again. Nothing.

Everything was working fine with this laptop up until I took those measures to shut it down to clear out the lagginess. Now I'm stuck with it in dead mode.

When the power cord and battery are in, the green battery light is on, both on the laptop unit and the power cord. When I remove the battery but not the cord, only a faint green light is on the laptop unit, though the green light on the power source is still bright.

It's obviously out of warranty and I feel like if I could just finagle a way to get the power button jiggered to work just once, I'd be back in business. Anyone have any suggestions?

Thanks in advance.
 

Oh sure. In fact, I'd wager the vast majority of motherboard failures are unrelated to misuse or accidental damage. They tend to arise from general electrical malfunction or possibly excessive heat over a given time. Sometimes the boards are fairly inexpensive to replace outright, but finding one and doing the work yourself (if you so choose) can be a pain. Still, replacing the board is often easier on the pocketbook than buying a new model.

But this is just a prognosis of mine from being in the industry. I do recommend you take it to a competent technician; they may be able to give you a better assessment.
 
I hate to say it, but you could be facing a damaged motherboard, given the circumstances. I'm dubious that there's any easy fix or "finagling" you could apply to get it started again. It's very possible there's hardware that needs replaced (or reworked, if possible).

Well as Jay Sherman would say, "That stinks." I've hardly moved the laptop in ages, so it hasn't been jostled around. Travelled with it in mid-summer but since then it has remained almost stationary on the same table. Is that common for a motherboard to get damaged even without a precipitating drop or other mistreatment?

Check the cable from power button to motherboard. You need to lift out the keyboard for access very small tape cable to motherboard connection has given me these problems. Remove cable and clean, very fiddly to replace, the connector has a small locking bar.

Best Regards
