How to Keep Laptop Battery Alive and Well

I've read the Windows 10 tutorial on battery saver, but it doesn't seem to address what I need to know. Neither do the various threads on same. I need to know if this particular "battery saver" will preserve my battery if I leave it plugged into the wall socket 90% of the time, or will it not?

I have an older HP laptop with Windows 10. On bootup, I'm told that there's a problem with the battery and that it will no longer charge at full percent. That laptop has been primarily used at home and is usually plugged into the wall socket, so . . .

Heretofore, I've been told that the above will happen to a battery when it's left plugged in more than 90% of the time it's in use. Which holds true for this particular laptop.

My new HP laptop with a 4-cell 41WHr-Lithium-ion Battery will be used for both travelling and home use, so I want to protect it as much as possible.

I don't want to continually pull the electrical plug and replace it when the battery runs down. This morning I decided to remove the battery from the laptop and boot using only the wall plug. So, will this hurt the computer? I don't think so, but I'm not an expert in these matters.

Bottom line: What is the best way to preserve my battery?

Thanks, Count. I gave the 17" HP its battery back, since it's brand new. It was definitely complaining about it not being there. However, FWIW, I'm going to unplug it and let it drain just because. :) There will be times when I want to travel and I'll want a battery to be up to par, so to speak. Although I do use the laptop at home mostly for testing purposes, I might want to use it when there are no electrical outlets too.

My 15" laptop has been telling me for sometime that it had a problem with its battery (which is why I asked the original question). When I ran whatever it told me to run, it said I need to replace the battery. Well, since this one is essentially a "stay-at-home" laptop and I hardly ever take it with me when I travel, I have not done anything about it yet. It's my Windows 10 test machine.

I got it out yesterday to see if there is anything on the next Windows 10 build yet, and once I checked, I started the draining process. Even at only a partial charge it took almost all day to discharge. Once when it got to 7% it asked me to plug it back in, but I declined. It shut down and I restarted it! About three hours later, it finally shut down and wouldn't even show a light when I tried to restart it once more. So I left it alone until this morning.

I plugged it in and voila! No more message! So, what I will do is to completely discharge it about once a week for the next couple or three weeks and then use it without the electrical cord more often.

I have something happening with the battery on the 15" laptop running Windows 10 that I don't understand.

As I said above, I let the battery completely discharge and then plugged in to the wall socket. My plans are to occasionally unplug the electricity and let the battery discharge while I'm using it.

However, every time I unplug the electricity, I get a runtime error:



I don't see how just unplugging the computer should give me this error. Any ideas?

Oh, crap. I've already lost one laptop. I don't want to lose another.

A program or part of the driver for battery charging control may be bad.

Would removing and then reinstalling the driver work ?
Or maybe trying to update the driver ?

I've never heard of a driver for the battery charger. Not to say there isn't one.

I can look, though.

I was referring to a driver for the program which controls charging of the battery.
