It's these new covid notebooks - they are fucking plagued. Normally you say battery - but there is a rash of these incidents on HP and Dell books. They all describe the same thing. So make and model number - the book/battery could be factory defective - search first for identical troubles with this specific model - maybe it's been solved already. At six months old, it is probably still under the factory warranty. Meanwhile - take the battery out - rub one side of the battery back and forth with the palm of your hand - not too hard, but hard enough to physically warm the battery a little. Rub from one end to the other. Big strokes:) 10 to 20 seconds of this. Then flip the battery and the same thing on the other side. Put the battery back in, and see if the battery works again. Make sure it is properly seated when you reinstall it. Don't forget to say nice words to the laptop in a soothing tone. You think I'm kidding? I'm not kidding. I've seen it work before at least a dozen times. Do not underestimate your own power level. Think like the electrons. Look how happy they are. Meanwhile, all computers come with an electrical hazard power safety feature. The power has to be good for them to stay on. We actually call this power good. The voltage must be clean and in the accepted range or the computer automatically shuts down. It's a fire prevention feature. The book is shutting down because the power is not good. If the electrons are not flowing, it is because they are somehow stuck, or there is a blocked or missing connection somewhere in the circuit. Some kind of bottleneck maybe, reducing the flow to lower than the acceptable range. That could be the circuit in the battery itself (a possibly defective cell, most likely,) or a hardware problem inside the notebook, (bad capacitor or something, rare but it happens.) ...or, maybe the electrons have gotten themselves clogged up somewhere inside the battery. Truth is, humanity does not yet know all that there is to know about the world of electrons. Your hand has an electromagnetic field of it's own. It's proximity can adjust how the electrons are parked inside the battery. Especially if it is a poorly insulated cheap Chinese battery from the mainland. Heat also causes metal to expand, and that affects the electrons as well. Heat excites them at the atomic level. Go real easy with the heat thing. Give it a shot - you have nothing to lose, and sometimes it works. Happy thoughts...
