Is really bad to keep a laptop on for more than 10 hours a day?

This is one of those questions where there is no single right answer. In other words, it depends on how you use your computer. \n\nThere are at least three situations that force you to leave your computer on 24 hours a day: \n\nYou are on a network, and the network administrators back up files and/or upgrade software over the network at night. If that is the case, and you want your machine backed up or upgraded, then you need to leave it on all the time. \n\nYou are using your machine as some sort of server. For example, HowStuffWorks has a machine that creates the images for the How Webcams Work article. It needs to be on 24 hours a day. If your machine acts as a file server, print server, Web server, etc., on a LAN (local area network) or the Internet, then you need to leave it on all the time. \n\nIf you are running something like SETI@home and you want to produce as many result sets as possible, you need to leave your machine on all the time. \nIf you do not fall into any of these categories, then you have a choice about whether or not to leave your machine on. \nOne reason why you might want to turn it off is economic. A typical PC consumes something like 300 watts. Let's assume that you use your PC for four hours every day, so the other 20 hours it is on would be wasted energy. If electricity costs 10 cents per kilowatt-hour in your area, then that 20 hours represents 60 cents a day. Sixty cents a day adds up to $219 per year. \n\nIt's possible to use the energy-saving features build into modern machines and cut that figure in half. For example, you can have the monitor and hard disk power down automatically when not in use. You'll still be wasting $100 per year. \n\nThe argument for leaving your computer on all the time is that turning it on and off somehow stresses the computer's components. For example, when the CPU chip is running, it can get quite hot, and when you turn the machine off it cools back down. The expansion and contraction from the heat probably has some effect on the solder joints holding the chip in place, and on the micro-fine details on the chip itself. But here are three ways to look at that: \n\nIf it were a significant problem, then machines would be failing all the time. In fact, hardware is very reliable (software is a whole different story, and there is a lot to be said for rebooting every day). \nI don't know a single person who leaves the TV on 24 hours a day. TVs contain many of the same components that computers do. TVs certainly have no problems being cycled on and off. \nMost vendors will sell you a three-year full-replacement warrantee for about $150. If you are worried about it, spend some of the money you are saving by turning your machine off and buy a service contract. Over three years, you come out way ahead!

Absolutely, but you will want to find a linux that has built in power saving settings.  Windows has features that will detect if the computer it is on is running on battery or on direct power.  When on battery, certain things are done to save energy: CPU is run at slower speed, consuming less power and running cooler.  The CPU fan is run less often.  The screen is run at a lower light level.  And the drives are parked and slept when not in use.  All these extend the life of the battery greatly.  You will want to find a version of linux that can perform these functions or the battery life on the notebooks will be very short.  Even more so since the batteries are very old by now.  If you plan on running the laptops on power all the time, then it will come down to your preference as to what version of Linux you should use.

Yes and no.  Speaking generally, the moving parts and power supply in your computer (fans and hard drive motors) suffer from being run constantly.  The electronic components suffer from voltage spikes when being powered on and off.  Many people argue that leaving the computer on constantly makes more sense; it's easier and cheaper to replace a fan motor than it is to replace a motherboard. \n\nTechnical considerations aside, leaving you computer running 24/7 will not do any serious harm to your system.  Neither will shutting it on and off once or twice a day.  Rebooting several times a day, every day, may have a measurable effect on your computer's lifespan, but it will probably make no practical difference.  It's much more likely that your computer will be obsolete before components actually start wearing out.\n\nThe overheating argument is moot.  You computer should NEVER overheat.  If it does, you need to fix your overheating problem, not ignore it by rebooting constantly.\n\nOne important thing to consider: Windows XP has an inherent memory leak.  It constantly writes to the cache while it's running.  Over time, this sucks up RAM resources, and makes your computer run more slowly.  This problem is less noticeable with high RAM machines, but most computers running XP will have a noticeable loss of system performace if left running for a week or more.  Unless you have special software for configuring your system cache (available on the internet), the only way to clear the cache and reset your memory is to restart the machine.

Yes. Easy. Go to  the energy saver in system preferences and regulate the turn off time there.

honestly, in terms of today's technology, it really doesn't matter at all.  Many times, people are worried that keeping it on will wear out the components, and sometimes that turning it back on will shock the components too much.  If you're buying a new computer every 4-5 years, it really does not matter

Nope - turn off the monitor, though, because that consumes a lot more power than the computer itself. Leaving your computer on is actually even better for it, because most failures happen when you turn it off and back on.

As long as the battery lasts.\nYou recharge and run it again.\nYou cannot run a laptop 24/7.\n\nhttp://360.yahoo.com/jcbroogley

Not unless you make some physical modifications to it. Closing the lid will place it into hybernation everytime and this is a safety feature because if the power stayed on and you placed it into a briefcase/computer bag it would overheat and destroy the laptop. Get a mp3 player/iPod.

its a way for your computer to save energy while its not in use.

In theory, it could damage your computer if it got too hot.  But it's not uncommon for a laptop that is charging to get very warm.   I've owned three Dells that could melt your lap and they've worked just fine.   \n\nUsually there is a fan that will kick in if it gets too hot.

no i dont think so except it is bad for your eyes, I do it all the time, even right now i am in my bed with my laptop sitting on my stomach....meh im on my pms..so its nice when its hot lol...

wear a rainjacket. it's highly doubtful you're getting radiation from your laptop tho.

It shouldn't.  Drives are designed to run for several hours.  Now if it were days straight then I'd worry, but an hour?  It'll be fine.

Yes it is safe. It will not hurt your computer. I hibernate my laptop all the time. It save me a lot of time when I need to turn it on. The only thing is that if you are using a laptop it will drain your battery but if you are using a desktop you will be fine.

I have an HP Pavilion zv5000 laptop, and its been very reliable for almost a year and a half, running it every day for at least 6 hours a day, and never had crashes or any bugs, running WinXP, although I did have to replace the power cord, cause I dragged it around too much (oops)

It's always safe to turn your laptop off. But you should install anti-spyware as soon as possible.\n\nHere are 2 good programs, all free:\n\nAdaware: get this at www.lavasoft.com. You can use it to scan your laptop whenever you suspect you have spyware on it, and it will eliminate alot of pests.\n\nSpyware Blaster: get it at www.javacoolsoftware.com.  It protects your PC from getting alot of spyware loaded onto it. \n\nIt's also good to have a strong antivirus program on your PC. If you don't have one already and want a free one, get AVG from www.grisoft.com.
