Is my HP Probook 450G8 losing too much power when I turn it off?
My laptop is an HP Probook 450G8 running Windows 10. It was made back in September of 2021, but I bought it last November. Recently, the battery drained way too fast after I turned it off and put it into sleep mode (S5). When I charged the battery to full power and then just let it sit in that sleep state for two weeks, when I turned it back on, the battery only held 57% instead of being at 100%. From what I know, there is no real need for electricity from the battery while it's asleep. The only thing that needs to happen is a tiny bit of power for the button. So I believe this extra drain is just the battery losing its own charge naturally over time, and that speed is too fast to be normal. Is 43% left after two weeks without using it okay? Or does my computer have a broken part inside? What if I take the laptop apart and leave the battery sitting alone by itself? Will the drain still happen at exactly the same rate every two weeks? Also, I noticed this happens right when I buy the laptop. But I forgot how fast the drain was back then, just that it went way faster than 10% each week.
Welcome to the forums, and happy New Year! You are too new to this forum yet you are already very old with your computer. It is beyond the return window... You could try some steps as a fix for this power drain. One way is to see if your laptop needs any BIOS updates. I'd try to find out which version of the BIOS it has and work toward getting that latest one, rather than jumping straight there if you have older versions waiting behind you. Another thing to check is if your operating system is pending an update. Often times the system comes with a computer full of bugs that mess up how much power the battery shows. You could also try seeing what happens when your laptop is turned off completely and left unplugged until you charge it again. A good way to care for your laptop's battery is to charge it all the way to 100% then let it get down to 10% while using it, and keep doing that over a few times. Don't plug in just to charge it and forget about it.
