Acer battery won't charge

Hi, my laptop Acer E5-475G (the spec is in my profile) is currently having an issue.
Last night I was organizing my files and document but I didn't realize that the battery indicator was blinking because the battery level was like 50% or 60%. I put the laptop to sleep when I'm done.

The next morning when I try to charge it, the battery didn't increased at all. I did some heavy task the battery didn't decreased as well. This also happened twice before when there is a quick power outage, the battery won't charge until I pushed the battery reset pinhole on the back of the laptop. I did the same thing now with no success. I've tried different charger with no success as well.

Does the battery failing right now? Is there anyway to confirm this? I have this laptop for around a year or two.
Thank you in advance.

If the laptop works without the battery then charger is functioning correctly. Take a cloth with a bit of rubbing alcohol on it (or some on-the-go alcohol swabs), and clean the metal contacts that connect your battery to your laptop.

Make sure to install all Windows important updates.

Install latest versions of your laptop device drivers you can download the latest device drivers from the device manufacturer or from your laptop manufacturer website.

2. Remove the battery.

3. Connect the AC power adapter to your laptop.

6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).



7. Shutdown the laptop.

8. Insert the battery.

Generate a battery report. Amongst other things, this should tell you the design capacity of the battery and its current maximum charge capacity. All batteries loose capacity with use so don't expect the charge capacity to be 100% of the design capacity, but for a useable battery it should be well over 50% design capacity.

I second Freebooter's suggestions for checking other reasons the battery may no be charging, but if it's health has deteriorated it may be time to replace it.

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file

If you can remove battery then follow the advice on Step 1.

I did step 1 to 3 but still no success. That mean the battery is faulty right?

Yes you will need to replace the battery with new one.

Already you have tried the battery reset, so need a new battery.

I tried that without success. The battery is currently unplugged right now, but I'll give it a try again later.

I am having the same problem on E5 576G... Am I right to think it's the new windows update? Or just a coincidence both of us have the same problem?
