Is there any danger in leaving a laptop on 24 hours a day?

As long as it's in a well ventilated area, there's no danger. At least, no more danger than there would be if you left your desktop computer on all day. The danger to laptops is overheating. Because all the hardware is in such cramped quarters, it tends to get very hot. The bottom gets hot, so be careful where you put it. You may even want to put it on something raised so the air can get to the bottom. If you leave a laptop on blankets or a bed, it will often overheat because the insulation of the material is keeping the heat in. A tip that may help you when you're transporting your laptop is to take out the battery to ensure that you don't accidentally leave the laptop on.

Important note : Beware of refurbished Li-ion laptop batteries for bargain prices, due to the volatile nature of the Lithium Ion compounds, batteries must have matching cells and correctly calibrated control & safety electronics. All our new laptop batteries are made to the highest standards by quality manufacturers that also make original laptop batteries for many of the big brand names. Refurbished Li-ion laptop batteries are usually sold at highly discounted prices and thus are normally produced for the lowest possible price, often with little regard for thier long term stability, this can lead to them overheating or in extreme cases catching fire or exploding, this one area where quality should not be sacrificed for cheapness
