Sometimes my laptop doesn't hibernate when its battery got empty

Question

Hi,
First of all:
I might be facing this issue if the battery is old and also if the Power Settings are corrupt.
The details of my problem:
Although the  low battery notification is ON, and Critical battery level is 5%, low battery level is 10%, and critical battery action is 'hibernation', as this screens shot below, but sometimes my laptop does neither notify me with low battery level/ critical battery level  nor does hibernate.
But with the same settings, some other times, it notifies me with the  low battery level/ critical battery level, and then it hibernates if I don't plug it in.
the Power Settings are  OK if we look at these screen shots.
This is strange, I am almost always used to using my laptop on a battery and with plugging in to the main supply power. But sometimes I forget to turn on the socket of the main supply power. And then, when my computer battery exhausts its charge,  my laptop shouts down suddenly (without warning).
As a result, I loss all my data.
When I turn it on again after shutting down due to its exhausted battery, I see an error message that my computer shout down accidentally, and several options ranging from starting in safe mode to start up normally. Then I start it normal.
Sometimes, I've seen this notification while clicking on the icon of battery in the system tray. Although my battery was charging,  in the notification in the screen shot below there's a cross mark on battery indicating to me that the battery needs to be replaced, which means the battery is corrupt.
In fact, I was advised that it is OK if I run my laptop on both battery and plug in. Thus, I have been used to running my laptop on both battery and plug in. However, I really noticed this destroyed my battery over time since it was lasting about three hours. However, it now became lasting an hour after it got full charged. I have a HP laptop (OEM). But the term(OEM) is really a misnomer because OEMs are not the original manufacturers; they are the customizers.
I don't think it is OK to run a laptop on both battery and plug in, do I?.
Thus, I don't know which type of battery I should buy if necessary.

Hi @cooperator ,
Thank you for visiting the HP Support Forums and Welcome. I will do my best to assist you. As there are many models of HP, I would need the model number. How Do I Find My Model Number or Product Number?
