so I have a Acer Aspire E5-574-G laptop, and have several questions about it. Firstly, I would very much like to replace the battery in my laptop with a better one with more capasity. Is one sold? if so, what do i get? secondly, I have the dedicated graphics card, and whenever the battery gets low it swithces to the intigrated graphics, even when plugged in. How can I make it use the dedicated graphics for the programs it usually would, even when the battery is low?
