Hi i have an old laptop Acer Aspire 4540, sometimes when i turn it on, the power light indicator is turned on but the laptop itself won't turned on, like just blank screen, nothing, and i decided to just wait, and suddenly after waiting for 30-more minutes it turned on itself. I've tried fn+f7, replacing the battery, and nothing wrong with shutting it down before (some says that it's stuck between sleep/turn on, like machine is on but screen is sleep), and i'm really curious why this happen? how to fix it so i don't have to wait for unknown time
