My Asus ux31 ultrabook suddenly decided to stop charging this afternoon. The charger has a steady green light, and the windows status is "Plugged in, not charging". I've restarted, tried different sockets, etc. No change. Any suggestions?

"Plugged in, not charging"

Not necessarily a fault or error. When the battery is fully charged (100%) the charging circuit is automatically disconnected until the battery falls below 100% again. This prevents the battery being overcharged.

That's the same message I see on my laptop when the battery is fully charged when I mouse-over the battery icon.

Sorry, should have specified. The laptop was draining while giving the message. As in, under 20%. However, it seems to have solved itself after a few restarts anyways.

Hi - hoping people find my solution useful. I have an ASUS UX32A, but am guessing that this problem is common to their Zenbooks. When the laptop is fully charged, it will say "plugged in, fully charged", unfortunately, some laptops just stop charging the battery and the light on the plug blinks red and green meaning a fault, and will never charge again. I have read in other threads that this can be fixed by uninstalling drivers and unplugging the battery, but this has to be done constantly. On my UX32A the battery went down to 4% and refused to charge at all, even when shut off. But I figured out what the problem was: it is in the BIOS settings, for USB charging when off, and allow laptop to go into low power mode when off. These settings were ENABLED on mine the day the problems started, and the problems stopped when I disabled them. So it must be a bug in the BIOS. If you have the same problem, try changing these settings in the BIOS.

Yes - if you have the problem that the laptop is obviously plugged in but it says it is not charging, shut down the machine, and then hold F2 and start the laptop and it will go into the blue screen BIOS. Look in the different tabs or sections (depending upon the BIOS) until you find something like "USB Charging When Off" or "USB Charger +", and if this is enabled, disable it. Also disable the setting for "low power mode when off". Then save the settings and reboot. These were the problem on mine; being on they caused the laptop to always say "plugged in, not charging" until the laptop batteries went dead. Probably Windows 8.1 is asking the BIOS for the state of the battery and the charging system and these settings are interfering and causing it to report an error, so Windows tells the charging system to shut down...

Just to confirm this - I have a Zenbook UX32VD which one morning last week refused to charge - the charger simply blinking orange and green at me. Have just disabled the USB Charger + option in the UEFI bios, and everything is working again. No idea why it stopped working (the battery has done 416 cycles, with 16% wear according to HWINFO - http://www.hwinfo.com/). Annoyingly I've already ordered a replacement for it - but I guess the spare will be useful.

So what do I do if my laptop is already dead flat and won't charge?

It's possible your battery is just dead for some reason, but probably not. Try changing the settings in the BIOS as described here, to disable all power features. Then reboot, and it should hopefully start charging again.

Wow, not sure. It should boot up with the powerpack plugged in even if the battery is dead. If the powerpack light is not on, then the powerpack is faulty. If the powerpack light is on but you cannot get it to boot, I would suggest open the back of the laptop and unplugging the battery pack, and then try to reboot the machine from the powerpack. If that succeeds, you could plug the battery back in and it should charge. If that fails, you must have either a bad powerpack or motherboard...

Thanks for the advice, unfortunately it was unsuccessful, all I know is there's no problem with the power cord, and the computer stopped charging as soon as the windows 8.1 update downloaded itself...

Yes, this happened to mine, too, it has to do with the power drivers that were updated by Windows 8. If you cannot boot the laptop at all, if it will not turn on, you probably have to open the laptop and remove the battery, boot up, reinstall the battery. If you can boot the battery will not charge, there are a lot of solutions on the web for this problem under Windows 8, most involve uninstalling the BATTERY driver through Control Panel. Will the machine go into BIOS at all?

Hi! My problems started as I upgraded to Win10. Just send my Zenbook ux32ln second time to service...

I think it has something to do with sleep mode. Both times I left my device alone to get some coffee. When I got back it was completely dead. It did not start up and did not start to charge. Even the led indicators wont turn on.

When using win8.1 I didnt have any problems. When I get my device back from service I will prevent it from going to sleep mode or switch back to win8.

PLEASE TAKE NOTE;

My problem arose when I converted to the freebie of Win 10....
.
Did not have to go into Bios; all I had to do was go into "Advance" on power settings;
and then I did change the status of to "disable"...
.
Instantaneously (upon hitting approve of the setting change) - status changed to
"Plugged in - charging".

Thanks MUCH - for putting me on the correct pathway!

Z here again,
Read how I solved the 97% Plugged in not charging" one or two posts ago. You can also call ASUS Customer Support, give them your serial number, they check it. then you get their help as LONG as you want it, even after a year!
Windows 10 horror stories??? I've read and heard a lot of them. Even with computers that have lots of RAM. Three negative remarks on this page including myself. Chuck win 10 in the trash as fast as you can. It's loaded with bloatware. Just wait until it automatically forces updates on you that you can't control! Windows 10 messed up one of my laptops, thankfully I got Geek Squad to fix it with my 3 computer Tech Support that I have with them. You have 30 days to uninstall windows 10. microsoft has done away with you being able to choose update options. They are now Forced on you. Some of the so called "security updates" do not have anything to do with security, instead they do things like Kill microsoft office starter if you had it. Best Buy had it in the computers they sold and when I updated, POW, no more office. That was the last straw for me, I bought Office Starter, included with my computer at Best Buy, then microsoft's updates killed it with a sneaky "security update". I thought it was mine because I paid for it. I realize they did it so it wouldn't be free anymore, but the way I see it, that's stealing! So instead, I just use OpenOffice and LibreOffice now. They're free, and as far as I'm concerned, just as good as microsoft Office. They'll also open up all of microsoft's old office files! I bought a new ASUS Transformer that came with microsoft office for a year free and uninstalled it. Soon perhaps, I'll get rid of everything microsoft and get a Macintosh. Of course, Linux, Ubuntu or some other free operating system would be a good idea installed in a computer that has had windows uninstalled out of it. (For those of you who still like microsoft, that's great, they're just not getting my money anymore) I think if enough people would say "we've had enough of microsoft doing these things" the company would start to tailor their software to suit the consumer (us) instead of them, or at least let the consumer modify windows 10, deleting completely, the things we don't want, like cortana, and other bloatware. Then let us control updates like before. My updates stay turned off until I go through each individual one, find out what they are, not trusting them just because microsoft says they are "Important" or "Security"
Some other microsoft sneaky "security updates" are:
KB3035583, KB2952664, and KB3021917 for windows 7
AND:
KB3035583 and KB2976978 for windows 8
THESE KB's are the windows 10 files they load on your computer disguised as "security updates" that put the little windows 10 icon on your taskbar. Some people want it some don't. I don't.
There is a "GWX Control Panel" you can download that gets rid of the Windows 10 "KB's". It's safe, I did it. Once you get rid of the pesky icon, and want to keep it off, do manual updating and check each individual one and find out what it is first before installing it. Next time I manually update, it's going to be interesting to see how many more of those so called "Important" "security updates" don't have anything to do with making our computers happy!
