Windows 10: Laptop with HDMI monitor: shuts down without low-battery warning

Hello,

I replaced my laptop battery around two years ago because it was not working well any more. The new battery is not the "official" one, and it has a larger capacity. At the beginning, the battery level that Windows reported was not very accurate, but, honestly, I did not monitor it closely because it was not too important to me.

Anyway, although I hardly take my laptop out of my home, I run it from time to time on battery because they told me to do that for the battery's sake (is it true, by the way?). When the laptop uses its own screen, it behaves as expected as the battery level drops: it eventually warns that the battery level is low, and it then hibernates.

The problem is that I am now running the laptop with an HDMI monitor (and the laptop's screen turned off), and Windows 10 looks incapable of doing a decent monitoring of the battery level in this scenario (with the external monitor). As the battery discharges, Windows gives no low-battery warning at all, and it shuts down abruptly. Then, after plugging in the laptop and turning it on, the start is "fresh": the programmes that I was using are not open, Chrome reports un "improper exit", etc. I even have to reconfigure Windows to use the external screen.

Does anyone have any clue about this? Any way to make Windows realise that the battery is running low and it has to hibernate, when using the external monitor instead of the laptop's screen?

Besides that, I would like to ask two extra questions that are in principle related to this:

1) Given that my laptop is staying at home for many months in a row, should I continue running it on battery from time to time? Would this help the battery compared to running it always plugged in?

2) I am using the energy plan "high performance" by default. Is there any way to make Windows automatically choose the "balanced" plan when running on battery? Also, is there much difference between the two plans? Which one should I use by default?

Thank you very much in advance.

:)

laptop shutting down before battery is low

is there a fix to stop windows 10 creators update from shutting down my laptop when i still have 50% battery left i noticed this happening after the creators update auto installed and at first i thought it might be the power settings which i tried i have
moved the warning level from 10% up to 40% in the power settings but that made no difference as i would normally run on battery down to 20% get my low battery warning popup and then plug in to recharge now i have since noticed that when my battery monitor
gets to 50% my laptop just shuts down ++ not sleep or hibernation ++ and any thing that i was working on is gone????????????????? after having checked the internet there seems to be lots of people having this problem and the fix's suggested don't work for
