Acer Aspire A514-54 losing 20% battery overnight while Idle. Any fix?

Hello everyone,

I’m having an issue where my Acer Aspire 5 (model A514-54) battery drops about 20% overnight, even when the laptop is completely idle.

Here’s what I’ve tried:
• Disabled sleep mode and set screen to turn off after 1 minute• Checked Task Manager for background apps—nothing unusual• Updated BIOS and power drivers via Acer Care Center• Unplugged all peripherals overnight—but still see the drain

Has anyone else experienced this? Any tips on what else I should check, or settings to tweak to prevent this overnight drain?

Thanks in advance for any help!
