Laptop losing energy while gaming

I'm not sure how common it is, but I know all my recent laptops have had a manual switch above the battery for toggling a bypass to it. As implied by others recommending battery removal, toggling that switch can theoretically be useful for optimizing efficiency when using the laptop while it's plugged in, and it's also useful for testing or working around certain battery issues. I believe it also continues to attempt to charge the battery when using this method, so you don't end up having to pop the battery back in on its own to charge it, after you complete your un-batteried usage. [I'd test that on my laptop, but I'm currently already bypassing the battery 'cause it's dead. :P]

That said, I believe there's a general assumption that any laptop with a non-removal battery is rather low-end, which makes it a bit surprising if such a laptop is able to run anything meaningful on it to begin with. Which is to say, are you confident the battery can't be removed, or did you just make an assumption based on not finding any release lever? I'm only asking 'cause I've seen some laptops hide the lever in tricky ways, or even make it so you simply have to pull hard on the battery to release it.

If you can't remove it then, well- it seems like it'd definitely stress the battery, but as noted by others, the process itself is perfectly normal (rather, the drain-and-recharge happens any time you have the laptop plugged in with the battery active, it's just that the recharge typically exceeds the drain). As long as you're not draining it to the bottom and crashing your game midway in, it's the same decision anyone with a lower-spec computer has to make: What trade-off am I willing to make between hardware wear and my approach to usage?

For example, I try not to exceed 40C hardware temperatures too much while gaming, wherever possible, while others totally don't hesitate to hit 80C (Generally, 90-110C is where your computer forces an auto-shut-off [though I believe some do it as low as 70C] while 60C is considered a reasonable maximum temperature by most, so both 40 and 80 are pushing expectations in different directions, with keeping below 50C being considered to be best for maintaining hardware longevity). Computers are designed to keep risks to hardware in mind, so most of the time your considerations are based less in "omigosh, am I gonna break it now" and more in "how soon will be an okay time for me to replace my computer".

:D I am not sure, if you were trolling or something. I know that PCs are better at gaming but back in the day (Feb 2018) I just wanted a better gaming unit and the local store happened to have a good enough upgrade for me in form of this laptop. I had a pc with some AMD FX with GTX 760 and 8gb ddr3 I guess. And that CPU was annoing as hell, because of it I had to get an other fan to keep it cool. It has such an issue, that if it hits 65°C, it does half the performance and it cools down to 60°C and it works normally again. And then the cycle keeps going and going. And then some day I built in a fan into the case and then the issue stopped. It was loud af but it worked :P Sorry for the story time
