Hello,

I've got a ASUS PRO66IC running Windows 7 64bit with all updates installed and I recently came across a strange problem with it. I rarely use it in battery mode since I'm usually close to a power source, but the other day i had to use it on the go and this is when my problem occured.

When the battery percentage (as indicated by the battery meter in windows) reached 35% it shutdown without warning. I tried to turn it back on several times but it would shutdown during start up (just as it would if there was no power left in the battery). When I got back home i connected the charger and the computer powered up just as usual, and the battery (still reading 35%) started charging just as normal.

I've been able to reproduce the problem several times since this initially happened, and its the same thing every time, it shuts down without any type of warning as soon as it hits 35%. At first I thought it was some form of battery reading failure, and that my battery actually was out of juice, but after further investigation this cant be the case. The laptop is fairly new, and from a full battery to shutdown (at 35%) I only end up getting about 50minutes of battery life (with all battery saving features turned on, lowest screen brightness and CPU speed etc, and usage kept to a minimum).

I've gone thru the event logs in hope of finding some sort of clue to what is causing the problem and noticed 5 "failures" of the ACPI, which i beleive deals with the battery, the event-id of this failure is 13. None of these failures have occured when I've experienced the problem, but I figured they might be related anyways.

The computer works just fine when plugged in to a charger and I havn't been experiencing any other problems, the "critical battery level" (and automated shutdown) is set to 5% and shouldn't have anything to do with the problem.

I havn't installed any strange software (infact, I havnt installed anything at all other than windows updates) or changed any settings since the time it was working fine.

Also, if anyone have a similair laptop, is your battery life as bad as mine? I get around 1min/1% of battery with maximum possible power saving (no wifi, lowest screen brightness, lowest CPU speed etc.)

I would greatly appreciate any help that could lead me to the cause of this problem, thanks!

I've been having the EXACT same issue with my ASUS laptop - so its great to see so many replies here.

I'm glad to hear that replacing the battery worked!! Did anyone else have success with just buying a replacement battery?? I'm most likely going to just do that, but it would be nice to hear that it worked for multiple people :)

Incidentally, when I first bought this laptop the battery worked GREAT and was my favorite feature of the computer (it would last at least 7 hours, sometimes more), so its extra painful to be dealing with this issue (although of course I know that batteries only last for so long!)

I have a similar problem. though not exactly the same, my laptop shuts off immediately after i unplug it from the charger. doesn't matter which end, what power options, whether its opened up or closed, same results. I bought the laptop in March, and have only recently been getting these problems. If replacing the battery works, then i want to try it as i think i'm still under warranty (not exactly sure :/). However, i dont want to go about the hassle of getting a new battery and what not until i am sure it works. I have read of a few examples in which this works, and some where this does not. can anyone tell me under what circumstances thi would or would not work?
Thanks in advance :)

I have a similar problem. The original ASUS battery wore out, so I bought a replacement generic. After a couple days, the power LED starts flashing green and yellow and the battery level displayed and time remaining stops decreasing. I checked the battery and turns out I bought a 10v battery, but the old was a 14.4v, so I exchanged the battery for the correct one and it did exactly the same thing.

I have an ASUS UX21E and I am traveling, so I am inconsistent in how I use the plugged in power. Suddenly it shuts down without warning. Battery power may be as high as 80% or low at ~30% or anywhere in between.
The laptop first had problems 3 months after I bought it, I had it repaired in Istanbul where they replaced the motherboard.
It was good for 6 months, but has happened again. It is currently in for repair in Lisbon. Let's see what they do to it.

I have a similiar problem with my laptop I'll be in a 4 hour lecture and halfway through my laptop dies, even when 35% is remaining.
I have to bring my charger with me everywhere. I'm thinking of buying another battery just to carry around so I don't end up ruining my adapter with all the travelling I put it through to and from school on my bike.

It could be that the battery still has that % of capacity remaining, but the internal resistance of the battery pack is high enough that the voltage drops too much from the load of the laptop. A good test would be if you run prime95 with it on battery power, if it quits at a higher % or even immediately, it may be internal resistance. Or, circuitry in the battery is confused and is cutting power when it 'thinks' there is too much load on the battery.

Just a possibility.

I have my Asus Zenbook UX-21E and I also have this similar problems.

I am using Debian as a replacement of the original OS (Windows 7) and the computer is just shutdown while the battery level is just about 70%.

In Debian itself, the charge level is about 70% with time around 1hr 18 minutes remaining.

After it turned off, I just tried to keep turning on and go into BIOS screen. I leave it there until several minutes without charging the battery and the notebook is keep going on.

It will dead again after about half an hour and I reboot it back to Debian and stay at the login screen. Surprisingly, it can stay about almost an hour at that screen before it turns off again.

And I plug in the charger, reboot to Debian and stay in the home screen and immediately I unplug the charger. The battery runs for almost another 1 hour and now the indicator shows a correct figure (I guess) and it down from 10% all the way down to 1% and do automatic turn off.

Now the battery is completely flat and I put back the charger. It may takes about 3 hour to do full charge and since then my notebook starts to behave normally.

Maybe this can help.

I had a similar issue with my ASUS N550LV where the amber charge light would not quit blinking and I could not charge it to 100%.

TRY THIS:
1. Open your Laptop and remove the battery.
2. Using a clean tooth brush carefully brush off the battery contacts (on the battery and on the laptop)
3. replace the battery.
4. Plug the AC adapter and connect it to your laptop.
5. Leve it until battery is fully charged.
6. Once the battery is 100% charged click Start button, and go to Control Panel.
7. Select Power Options, create a new power plan by clicking Create a power plan.
8. Name the plan something like Battery maintenenace , then click Next.
9. Select Never under battery value for "Turn off the display" and "Put the computer to sleep" then click Create.
(This will prevent your notebook from turning off the display and entering Sleep mode to help drain battery faster).
10. Next unplug AC power adapter.
11. Select a movie to play or a DVD or a MP3 file and loop it continusly.
12. Set yory WMP or VLC player to repeat mode and start the playback.
13. Allow the player to play until the laptop turns off.
14. Plug in the AC power and restart your laptop, and let it charge it to 100%.
15. change the power plan back to your default plan.
Hopefully your issue will be resolved as mine was.
use as normal

I recommend doing this once a month to help ccle the battery fully and calibrate the battery,

CB

I found the solution to this problem. The problem is not with the battery but an Asus bloatware called Power4gear Hybrid. This app messes with the battery notification settings. Just uninstall this POS and you won't face this problem.

I can't believe why Asus support never had an answer to this easy problem.

Update : The problem still persists. What I did for my windows OS was go to command prompt and get the battery report. The report clearly shows that my batteries full charge capacity has reduced . While the design capacity was 57,200 MwH , the battery capacity now has reduced to 24,816 mWh. So the problem is definitely in the battery.
