I picked up an Asus L402WA for less than $200 for use as a basic home laptop. Watching YouTube, social media, surfing the web. Basic tasks. It's great aside from the battery life. I'm only getting like three hours on a full charge. If that. I did update it from Windows 10 S to Windows 10 Pro. I've usually used Mac's in the past, so PC's are semi-new to me. Question is, would updating the BIOS or anything else fix the issue? I did find the below page on the Asus website. Would downloading any of those updates likely fix my battery issue? I read online that messing with the BIOS can brick the machine, and I don't want to do that. Thanks for any help.
