Laptop vs desktop- Is it ok to use laptop for 12hours straight?

Is the laptop connected to an external power source or are you using the battery? If the battery will last that long, it should be safe enough. If using external power it should be okay as long as it is not getting hot. I used to use my sons laptop for long periods of time and it was alright. I tried to keep it cooler by making sure that air could get around it. I live in the desert and it gets very hot here without any air moving around.

There really isn't any reason why you cannot leave your laptop on 24/7 but as others haver stated already you MUST make sure that it is properly ventilated if this is the case. I use my laptop for periods of up to 48 hrs at a time sometimes. For ventilation I would recommend that you get yourself a laptop cooling pad. They are a most wonderful invention. I keep it on all the time while my laptop is on. http://www.coolerguys.com/noco.html

Just keep it properly ventilated and it will work just fine. Check also that your Window Power Settings is set to portable so that it doesn't consume much and reduces heat by turning devices off during period of inactivity.

Me and my fiance own a laptop,and we never use it for more than a couple hours at a time,to keep it from over heating,because the laptop seems to get very hot,as so does the battery back,so my recommendation would be to no use it for more than like four hours at a time, before letting it cool down.

When you're using your laptop place it on a table or something. Don't use it for 12 long hours on your lap or anywhere near you. The thing is it gets really hot when used for hours, it could affect your health. Heat, radiation, overexposure to these is very dangerous...

Laptops are well worth the extra money for their portability and size. As long as you get a well built one and dont go cheap and buy a bad one, you should have no problem using it for extended periods of time. I use my lenovo for a couple hours each day and have no problem

Hi pau! It's okay to use your laptop for even more than 12 hours straight just make sure that your laptop is elevated (it's not laying flat on the surface) to avoid over heating, make sure air could get circulate. I suggest if you're using it that long, keep your laptop charging. That's what I do with my Mac. I avoid plugging it in and out when I am just at home and I can conveniently plug it in the entire time. My current uptime is at 2days 16hours 6minutes. That's how long my laptop's been on. I didn't put it to sleep nor shut it down for more than 48 hours. It's working perfectly fine. Just don't let it tire out too much.
