Internal Battery Resert required to fix recurring problem

For the 2nd time in a few weeks, my Acer Aspire 515-51G has refused to power on with a nearly fully charged battery. Both times, I had used the system on battery power for an hour or so, hibernated the system, then later, tried to power on - power button has no effect at all. Both times, using a paperclip to do an internal battery reset has solved the  problem. But, what does this mean? Is the battery going bad? Something else failing? The system, 2.5 years old, is plugged in for long periods of time (days) between being used on battery power. I really like it and hate to think of replacing it.

    >>>maybe a recent Windows update(?).>>>maybe the power required in sleep mode is so minimal that it won't make a significant difference.>>>

    Bingo! And Bingo!

    However if the very minimal battery drain difference between hibernate & sleep still bothers you,  you can still go back to the previous Win10 version with ControlPanel's restore point app (assuming SystemProtection was turned on) and temporarily block the errant update till it hopefully gets fixed in a future update using Microsoft's update hide tool.   https://support.microsoft.com/en-us/help/4026726/windows-hide-windows-updates-or-driver-updates

    None of my sleeping laptops lose even 1% charge over a period of several hours unplugged. And even if they started out sleeping in a very low charge state, hibernate will automatically kick in anyway even in sleep mode once the battery reaches a low critical charge state.

    >>>hibernated the system,>>>

    Hibernation is a Win10 system issue on many laptop models, not a hardware issue. Open ControlPanel. Search 'button'. Click 'change what the power buttons do' in left pane. Change all settings on battery and plugged in to sleep, none to hibernation. Jack E/NJ

    Thanks for the reply. The system is 2+ years old, operated in the same fashion the whole time, and 2 weeks ago was the first time this happened. If it is a Windows problem, I wonder why now - maybe a recent Windows update(?). I intentionally use hibernate vs sleep because it's not drawing battery power. When it's plugged in, that's not a problem, but when I grab the system and leave home, it's going to start draining the battery. I guess I could try to be careful to do a full shutdown before taking off for somewhere - or maybe the power required in sleep mode is so minimal that it won't make a significant difference. I'll give it a try.
