    I bought a used 2018 Razer Blade Advanced with the 80wh battery. I have had many laptops and I am aware that batteries get worn out. So, naturally, after a few weeks with the "new" laptop i decided to order a new battery. I got a razer branded battery and installed it. My issue is that unless I charge the computer when it is off or in the bios I only get around 35wh of a charge. Anytime i charge it while the laptop is on and in windows it will show 60% or so wear. I only get about 1 hour of battery life even under light load. It seems to work fine if I charge the battery in the BIOS.

    Is there a way to reset the wear that windows thinks the battery has? I have tried running it down...charging while on. Removing the battery and then uninstalling the drivers and reinstalling once i reinstall the battery. Always ends up the same. I have contacted the company i bought the battery from as maybe it is just a bad battery. However, it does seem odd to me that it will charge fully in the BIOS.

    Any help would be greatly appreciated.

    You can recalibrate the battery by reinstalling ACPI under the Battery tab on Device Manager. Do note that we do not ship out parts for our systems, and the battery you got may not be up to spec. In any case, send me the serial number if the problem persists so I can point you in the right direction.
