Acer a515 Baterry showing 0% but is working fine

Yesterday my acer a515 suddenly went to hibernation mode without any warning what so ever. To make matters even weirder hibernation mode was off (grayed out). Anyway after turning it back on, the battery started to show 0%. Just like this pic:

Did a bunch of turn laptop off, unistall drivers, removed the battery (had to disassemble the back plate). hard reset holding power or paper clip on the reset little hole. But still is not working. So I had the brilliant idea to unplug the charger with the thing on. And is being on for more then 2 hours already. If the laptop is unplugged from the ac charger I won´t turn on. But if is already on it will not go off by unplugging. So I imagine the battery is charged and working. But windows can't actually detect the battery.

Any tips?

While the battery's energy capacity (watt-hrs) might be OK, it may not be able to provide enough current (amps) or power (watts) fast enough during the initial startup boot process. Sorta like inertia. But once up and running with the help of the charger, it can deliver enough amps to keep the system on when the charger is unplugged.

I suspect that under heavy gaming or program load when the CPU/GPU and storage hardware power demands are high, the battery alone might not be able to handle the current or power demand and immediately shut down.if it isn't plugged in. If it's just sitting in an almost idle low amp low power mode, then I can see that it might not shut down right away. I'd like to see what happens when you stress load the battery,

(1) Shut machine off. Unplug charger

(2) Insert paperclip into battery disconnect pinhole for 30 seconds

(3) Plug charger back in

(4) Wait for battery charge LED to turn steady blue

(5) Unplug charger

(6) Try to turn machine on again without charger

See that the battery wear is at 100%. I would consider changing the battery.

step 4 battery LED indicator is always steady blue.
step 6 doesn't work. I can't turn it ON when the charger is not connected.

I don't think this is a good measurement since is more like the app can't really read how the battery is performing.
That reading feels a lot more like a false positive.
The battery is working when unconnected. I just get no measurements what so ever.
Yesterday I left the pc unconnected for more the 2 hours and it was working fine.
Is like a car that stopped displaying the proper speed. Even if the car is moving the metrics would show 0 speed

Guess I'll test it out for ya.
Don't even have steam on this machine since I dropped from PC gaming after getting married.
Time to look at that steam library

Dude you are the man! Like THE MAN! The bosss! Like a Bauss!
I left the notebook with a game running (grim dawn at 30fps) and about a half a hour later the pc got killed.
All leds off.

When connecting the charger I got a orange led on the battery (charging), already god news.
And when windows booted it was showing that the battery was indeed charging again!
It charged all the way back to 100%!

Thanks so much! I was already looking at replacement batteries online!
You save me some a lot!

Congratulations. Thanks for reporting back. But before you stop looking for replacement batteries, it might be useful to see what your batteryreport looks like now particularly comparing original design capacity with its current 100% capacity
