[closed] Do you keep your computer on all day and night, or do you shut it down?

One thing to keep in mind is that the battery (on laptops) will degrade if you leave your computer plugged in all the time. I have unplugged one of my laptops maybe 15 times in 2 years, and the battery lasts about 5 minutes. Just keep this in mind, because batteries are expensive. If you use your laptop as a desktop computer, as in you don't take it anywhere, I would remove the battery and then plug it in when you want to take it somewhere. This won't make an impact if its only a few days, I just don't have any powerful desktop computers so I use laptops.

Also, I personally have never had hardware go bad on me. Most hardware is built to withstand the lifecyle of your computer. I guess I could recommend not shaking violently, and avoid spilling stuff on your computer. Also, powering on and off constantly is bad practice, but I don't know anyone that does that.

I always keep my laptop on 24/7, except for updates and if I'm going on vacation without a car charger. Putting the computer in power-saving or sleep mode would prevent it from actually doing much of anything (HDD spinning, fan running, etc.) so it really shouldn't have any impact on the computer's hardware, and of course, software would be out of the question, so leaving it on would be completely fine for the compuuter. (Just make sure it goes into sleep mode so that no hardware is running and the screen doesn't burn in.

I turn my desktop off at night while I leave my macbook pro in sleep mode

It's up all night, I got servers running and I need them to be continuously running so I don't have to restart them and it might cause some troubles.

on all the time, all day all night

I sleep my MacBook Pro whenever I'm not using it, see, I'm making use of its features =D

I will also turn it off every.... like 5 days?

It's fine to keep a desktop PC on 24/7, but it will be constantly draining power so that might be a problem if you have to pay the power bills and you run a high end machine.

Most laptops will run fine 24/7, but their batteries will degrade over time and it will get used to being on mains power. It's recommended by most people that you should drain your laptop battery at least once or twice a week to keep the battery in best condition for as long as possible. It's going to wear out eventually though.

Personally I turn my screens and PC off at night because chances are if i'm watching something on it in bed then i'll have fallen asleep before it finishes so it will be simply sitting there drinking juice and doing nothing, making my power bill bigger for no reason.

However, you can set most PCs and laptops to automatically shut-down or sleep after 30 min to 1h.

If you hate constantly booting your computer then i'd either A) Get a new one with a new hard drive or B) Upgrade the OS drive to an SSD.

If you have a server PC that runs 24/7 then you are going to have to take the power punch.

My MacBook is on a schedule. On at 10am (summer), sleep at 4am (unless I'm still awake). Sleep mode when at work, as well
