사용자에게 답변하기: Why won't my battery last as long as it is supposed to?Laptop batteries typically need to be replaced every couple of years because the ability for the charge to be held diminishes the more you use it. I recommend looking for a replacement battery online and follow this guide to replace it. It looks pretty easy as it's only a little spring loaded slider that has to be pushed before the battery pops out. It looks like they also have troubleshooting information for this laptop here if you come across any other problems. Good luck!
