I rather turned off my pc than letting it on for the whole day or a week, or on sleep mode, or hibernate. Why? because I've done all of this and the result was my motherboard got busted due to overheating. the worst thing here is if your laptop motherboard got busted is like you've purchase a brand new laptop because of the price of your motherboard is much higher than other hardware in your system. Buy a high end system that boots in seconds, that solves your problem in causing delays in starting up your pc. Thats all thanks.
