I wrote about the battery life of laptops about two years ago. Another reason to rewrite it is that laptops have changed in appearance and processor upgrades. It is not yet possible to get rid of laptops when it comes to carrying mobile phones and tablets with you wherever you like and carrying them around. Laptop replacement has not yet appeared, but it is now known as a convertible laptop. People are addicted to tablets and can use them as tablets. And computers that can be used as laptops. Its advantage is that you can remove the keyboard and use it lightly. Touch screen On some computers, you can write using a stylus. Better battery life than regular laptops. So what is the weakness? Laptops, however, have lost the power to connect to home lighting.
