Hello, everyone. I hope you are all well.
I needed some help on some battery issues with a Gateway KAV60. It used to have a battery life of about 3 hours but now it had reduced to just one. I need it for taking notes and, therefore, need a better battery life. So, what can I do to increase the battery life (apart from the general tweaks like reducing brightness)? I am mainly focused on hardware solutions but if you know any useful things to do with the settings (like the brightness) you may as well tell those. Since it used to have a better battery life, is the problem the battery? If I buy a new one, will that solve the problem? Or, is it because the computer itself has "aged"?
Any help is appreciated.
