I have a G9-793. The battery suddenly quit charging but AC adapter runs the laptop as long as plugged in. I pulled battery, no deformation, reseated DC cable connectors. Looked the main board over, but saw no obvious issues (hotspot discoloration, etc.) Laptop was fine until about 10 days ago.
I ran a powercfg/batteryreport and it showed a design capacity of 90,000 mWh and it showed the max charge capacity as dropping steadily down to the last entry being some 65,595 mWh.
Does this sound like time to get a new battery?
Thanks for the help.

    If the battery charges and discharges quickly/not accepting any charge at all yes you probably need a new battery and its normal when the battery is faulty it wont let you upgrade the bios because if the AC power fails by some reason and you dont have the battery to keep it running until it finishes the bios update and you would brick it thats a security measure have u tried battery pinhole reset and let it sit for a few hours boot into bios reset to defaults probably also uninstlatt the acpi driver and reinstall to see if it gets sorted but as you said the battery had 90,000 mWh and the last battery report read 65,595 mWh theres about 25000 mWh wear there that you lost in that battery i would get a new one just in case

    Bill here, I posted the question I am comment on here (not knowing how to edit to add information to the original). I did try to add a layer of tape as a spacer over what I think is a very small power disconnect switch beside the RAM nest. That does not seem to have helped, the Windows taskbar still says the battery is not charging.
    Add to the confusion, the machine wants to update firmware but will not unless the battery is "above 25% charge." For some reason it does not accept the AC adapter as sufficient. I could sure use some help here. Thanks folks.

    Thank you. I will try your suggestions, they make good engineering sense. My download of the G9-793 manual will not open and when I retry to download, it hangs about halfway downloaded, so, I have not been able to locate the "battery pin hole" to do that reset. Can someone point me to that pinhole? 
    Also, is there a problem with leaving the layers of electrical tape on that power disconnect next to the RAM boards or should I remove that?
    Thanks again.

    Hello again, unfortunately. I tried all the suggestions Xapim offered (very good suggestions in my opinion), but the problem persists. My battery still is not accessible according to  Windows. The orange battery light comes on for a couple of seconds every minute or two but it goes back off and repeats (I guess that would be called a slow blink, very slow). The laptop tries to update bios on startup, cannot due to the battery not being available and makes me restart so it will boot to Windows.
    Does this sound like a battery issue or a main board problem? I do not mind purchasing a battery but would rather not if the problem is a main board repair.
    Thanks again for whatever help is offered.

    Well if you are still under warranty i would contact acer support or you seller/shop and send it in if not if it was me i would try to buy a replacement battery 

    PS: before you send it if still on warranty try to recover/backup any data you might need to another pc/laptop you never know if they would format it or not

    I am off warranty. I think I will give the battery a try. Thanks for all your assistance.
