I have somewhat of a complex problem with my Asus laptop (roughly 1 year old). It started when I required a screen replacement for my laptop, which I ordered and installed, and only after failed attempts to boot realized that I was sent the incorrect screen, even though it fit my connector, and long story short I have the correct one now. Ever since this, my battery has displayed as "Plugged in, charging," when in fact it remains at the same per cent. When I unplug the AC cord and try to put it back in, the "Plugged in, charging" goes away and it fails to recognize the external power source at all, running exclusively off battery power. After many attempts to unplug and re-plug, often upward of 20, it will eventually return to the "Plugged in, charging" state, and sustain the battery at 27%. However, I don't think it's a problem with the cord or AC jack, because if I shut down, remove the battery, and boot simply from the external power, it works every time with no detection issue. I've tried reinstalling the Microsoft ACPI software, leaving the battery unplugged and holding the power button down for 30 seconds, all the basic/obvious stuff. I'd just like a second opinion before investing in a new battery.

If I recall correctly, ASUS does cover batteries but you will have more knowledge on that than me. Try calling ASUS and see what they can do for you. It's most likely that they will replace it if you are under warranty still.

Get the battery. I every case where it's plugged in charging, but isn't, a new battery has always fixed it for me. It's likely the battery lost it's cell memory or has simply aged to the point where it's done. They only have a specific number of life cycle charges in them and running them on AC power when possible is the best way to ensure they have a long life. That and not letting them go fully dead, especially for extended periods.

You might have a bad battery. What I would do to make sure that it is a bad battery is to take out the battery, plug it in again. If your laptop powers on, you have a bad battery and I would most certainly advise you to invest in a new battery.

Yes, if I unplug the battery, I can boot off external power from my AC cord just fine. Just strange that it would crap out after only a year, since I run off AC power about 98% of the time. Probably more, actually.
Is it most likely just a coincidence that it started doing this after attempting to boot with an incompatible part, or could that possibly have something to do with it? Just wondering if I could get the battery under warranty or not.

That was just a way to verify the integrity of the battery.

Only reason why I told them to try that was because that was how my cousin found out that his laptop battery was a bum. Thanks! :)

Yes, yes, of course, that was meant for the both of you. Didn't mean to come across as picking favourites, hehe.



Thanks also for the reminder. No way I'm doing that.

Mine just started doing the same thing
I have a ASUS G75V that's a couple years old. Rarely run on my battery, mostly always wired in.
One day I left it on unplugged. Next day it won't boot up at all on battery

When plugged in, it says "plugged in charging, 45%", but it's stuck at 45%....and if I disconnect the power cord, it just dies (clearly the battery isn't holding charge at all)
Can this really happen over one fully drained charge?? Am I left with trying to ebay a battery replacement?

Laptop batteries just fail sometimes. That particular model might have a battery issue. I'd replace it with a quality Anker replacement. They're more expensive but they have outstanding quality and generally have replacements with higher mAh values than the original available in addition to ones with similar capacity to the original but better quality.

Alright, I have somewhat of a disappointing update. I purchased a new battery and received it this morning. Plugged it in, rebooted my laptop, and it immediately recognized the AC power input without any need for fiddling, which was an improvement. However, I'm still stuck with the same issue beyond that. "61% available, plugged in, charging," yet the percentage never goes up.

Like I mentioned earlier, when I had connected the incompatible screen and attempted to boot with it installed, the laptop received no power whatsoever, the battery LED indicator didn't even turn on, which makes me think some emergency power shutoff precaution was activated. Would that perhaps have messed something up on the motherboard, and if so would it be fixable?

Don't you need to re-calibrate the new battery?

Remove the battery (Operate on AC only)
Delete the ACPI Compliant batteries in Windows Device Manager
Turn off the computer
Remove AC for 30 seconds
Replace battery
Replace AC and leave til charged to max (indicates stopped charging or just leave for 12 hours).
Turn on computer, ACPI battery devices will reinstall.
Remove AC
Turn off any low-power/power saving shutdowns/hibernate etc
Leave computer on until battery dies
Plug in AC til fully charged (device can be on)

Battery should be calibrated.

That's true... Silly mistake on my part. Anyhow, it miraculously fixed itself and started working last night, so all is good.

if I may chime in .. I have an ASUS laptop (less then a year old) it wont hold any charge and it only runs on ac power if I unplug the ac cord it will shut down and when its on I check the battery indicator and it say " 0% available plugged in charging" and 2 hours later still at 0% ive tried putting it to sleep and restarting it and nothing seems to work. I did just update to windows 10 could that be a factor? please help its kinda frustrating if I do say so myself (edited) my asus computer the battery doesn't come out its like built in

I'm having same problem with ASUS TP300LA. Searched entire web (somewhat common problem) and tried every solution incl those mentioned here) and NO LUCK what so ever. I tried upgrading from 8.1 to 10 same problem. Here are the things I tried:


1) Power cycle system by holding down power switch 10 seconds (reset by no go as expected).

2) Delete ACPI drivers in device manager and restarting (no go)

3) Recalibrate battery - remove back cover/unplug battery/charge for at least 1 hr/turn on and delete ACPI Driver/Reboot (no-go)

4) Tried installing 4 various Windows 10 Asus bios/drivers from website (no go).

5) Tried turning off ACPI driver and let charge (no go).

I have been on ASUS phone support for more than 10 minutes now (after thee hung up on me on 15 minute wait).

Good luck but as a VERY experienced and technical user who owns/owned numerous laptops (4 laptops in last 60 days - Lenovo Thinkpad/Sony/ASUS TP500 (so far no problems)/ASUS TP300L, this is becoming one that goes on my do not buy list!
