    Did you contact technical support, or find another solution?  I am having the exact same issue (at 60%)!  and of course out of warranty by a couple of months. 

     

    Thanks,

    I have the same problem, bought a new battery, it charged for a minute and now it won't charge! Did you get an answer?

    CAM, can you post your model number?

    It might not actually be at 60%. Because I don't know your model number I'll give you the failsafe method. What you want to do is first go into the device manager. If you don't know how hit the windows key and the letter R on your keyboard. It will open the run command, now type DEVMGMT.MSC and it will open the device manager. Look for battery and in the drop down look for Microsoft ACPI something or other. Right click it and select uninstall. As soon as it finishes restart the computer. We will now go into your BIOS. To do this tap F2 repeatedly after you turn on the computer and before you see the Acer logo. Keep hitting it until you see a blue screen. Once you're in the BIOS unplug the device and leave it sitting until the battery dies completely. Once it shuts down plug the device back in and power the unit on. Let it load into windows and it will reinstall the battery driver. Now the battery level is at 0% and the system will read the same. Let the unit sit for 6 hours and the battery should be reconfigured.

     

    Hope this helps and take care,

    Hi,

     

    I also have a battery charging problem with an Aspire 5738Z. The laptop's original battery was pretty shot after 3 years use and I purchased a new one 2 months ago. Initally it charged to 100% but it then started to drop down a couple of percent after every charge and it is now down to 71%. It then stops charging and says 71% available (plugged in, not charging). I have done as is suggested in this thread with no luck. I have also checked other advice columns for different computer models with the same battery problems and all suggest basically the same procedure with some people claiming it fixes their problems and others not. So experts out there - is this a battery driver problem - microsoft won't take any blame for it or a computer hardware problem with the charging circuits. The battery manufacturer acknowledges there might be an "incompatible software with the battery" but only suggest either ignoring the battery meters values or alternately running with the meter. Come on Acer step up to the mark and tell us what is going on here, you only have to search the web to see that there are a lot of people with the same problem and there must be a fix!

    I meant of course " alternately run without the battery meter"

    You also only have to do a quick Google search to see that this doesn't just happen to Acer products. As a matter of fact there isn't a single mark that's excluded from this issue. That being said you need only ask what do these systems all have in common. Same ram? Maybe. Same HDD? Also possible. Same OS / Microsoft AHCI driver? Almost every time...

    JohnMoran, this probably won't work, but it's free. Turn off your rig, unplug it, and remove the battery. Hold the Power On button down for one minute. Put everything back and restart. This wil SOMETIMES clear up a BIOS problem or a battery settings problem.

    Hi again,

     

    tried uninstalling the driver and draining the battery in BIOS mode and then recharging for 6 hours BEFORE booting up windows (no driver involved). After booting up windows the battery meter showing now 69% available (plugged in, not charging). To make sure the battery meter wasn't  just showing the wrong values I then ran the laptop on the computer and only got 1.5 hours when I got 2.5 when the battery was new. So doesn't this tell us that it has nothing to do with the ACPI driver? Any ideas out there?

    This could also be caused by a voltage drop in the adapter. If you have another one laying around I would say try it out, and I know it seems unlikely but it happens more frequently than you would think.

    Tried Vince53's idea with no change. Tried another adapter from my son's Acer computer after letting the battery level go down to 65% and it charged up to 69% and then stopped at 69% available(plugged in, not charging). Now it seems to me (and I'm no expert) that most things have been excluded except Acer' hardware charger circuitry and battery sensors, ... and the new battery. Any ideas?

    Update. Battery meter now showing 59% available(plugged in, not charging). Thinking it must be the new battery so I am trying to get a refund and get another one. Thanks for all the help!
