is it safe to keep the UPS inside the personnel's office in a data center?From where the UPS gets power towork

It depends on the batteries present in UPS. It there is drycell Batteries then u can keep it inside your room but if there is liquid batteries in UPS i would suggest you put it in a airy place or atleast at a place where a proper ventilation is present. \n\nAs far as Power of UPS is concerned, you have to charge batteries from a wall socket. once batteries are charged you can use UPS with plugging it into wall socket.

It's safe, your hardware only pulls as much power as it needa from the power supply. It wont overload anything, if that's what you're worried about.

Yes it is perfectly safe, The device will only draw the current it requires. So as long as you are providing at least 300mA the device will operate without being damaged.

You would need to refine your question with some kind of definition of 'security' (computer, physical, etc)

There's no truly effective way to prevent loss of data when somebody has physical control over a device.  You can put in BIOS passwords, but they can open the case and reset the BIOS.  Likewise, the drives can be removed.  So the best way to prevent these kinds of problems would be to just maintain positive physical control over your hardware.

Yes, the surge protectors are needed. If you have a spike of energy which A/C power often gets, it needs to be regulated and your home or office power outlet does not provide that feature. It is simply better to have it than not. Belkin is a good provider of surge protectors for home and office use.

I would recommend not.  Two years ago, my Sony Vaio's telephone modem suddenly stopped working during a lightning storm.  The lights hadn't dimmed or anything, so I thought it was just a glitch.  The technician said that just because the power supply was protected by a surge protector, the phone line (which was not plugged into a surge protector) experienced a surge when a telephone box blew a few blocks away (it was a bad storm, but I just had to check my email).  The surge wouldn't have hurt someone on a normal phone, but was just enough to disrupt my delicate computer.  So unless its urgent, or you can work off the power grid (like a laptop), I'd just leave the computer turned off in a storm.

There are quite a few things you can do to keep your PC safe.  Take a look at the paper at the link below in Source(s).\n     Although the paper is intended for business end user devices, the protection principles are the same when deciding how to protect your home PCs.\nIf you'd rather not wade through the paper, you can also visit http://www.adventuresinsecurity.com/podcasts.html to listen to the End User Device Security podcast series.\n\nHope this helps...

because it wont harm your computer if you turn it off when its safe.

Yes because sometimes lighting can get through the electric lines and damage your PC if the building does not have proper "earthing".  Safer still, after turning off the computer, remove the plug from the socket too. Replug only after the storm has gone

I'll try to return the favor of answering your q...\n\nI have a couple of decades of hardware experience, and your problem is one of the more difficult to pin down quickly. It's possible you have power supply problems (your electrical system). If the voltage dips "too far" (how far is too far depends on the electrical device) then your Compaq may shut down. Different computers, even different Compaqs, may shut down more, or less easily as the voltage coming from your wall outlet sags below 120 volts. You may, or may not, notice the lights dimming, but it may still be enough to trip the off circuit in your Compaq. If you don't have one yet, spend $40+ and get a battery backup (UPS). It'll help any system last longer, too. I like the APC UPSs.\n\nSecond possibility is that your Compaqs power supply (internal silver box) may be getting flakey. I haven't worked on a Compaq in a long time, but they used to have "custom" (proprietary) power supplies that required going back to them (Compaq) for a replacement (at a premium price). If it's a standard size/shape, then a new power supply is only around $50 to $60 and available at most local PC stores. Not a lot of expense, and easy to replace for even a novice. (Please uplug the system from the wall first, and try not to touch any electronic components inside the computer during your foray into the inner-world of your Compaq.)\n\nIf you still have trouble after confirming your electrical supply is good and your power supply isn't causing the shutdown, it is -slightly- possible you have a bad hard drive or mainboard. Replacing either of these is doable, but not for the non-tech. If you have a spare hard drive, you can just install it (replace your current hard drive) and fire the system up...let it sit...if it runs for a substantial amount of time longer than it usually does, then you -might- have found the problem. \n\nFinally, you may just have a heat problem. Try making sure all the vents (front, side, back) are clean and clear of obstruction. If you feel competent, take the case cover off and blow out the dust inside (but take the system OUTside first!). I've seen systems in relatively clean office environments build up a half-inch of grey fuzzy 'lint' all over the inside in less than a year. Even if this doesn't fix your problem, it'll probably make your system last longer by running cooler. I've seen hard drives that ran as low as 90 degrees F, and as high as 175 degrees F. The lower the better...within reason (less than 120F should be fine).\n\nHope this helps.

Well, mini skirts are out !!! shame.\nVery difficult to have a secure area when it is open space office.\nMake sure you have a good code for your computer, drawers are locked with all confidential documents kept away.\nWhilst working always have a paper to cover the file being read so that you can cover it when someone approaches your desk.\nAsk the Management for suggestions and implementation of policy on security.\nI could go on and on, but really, the bottom line is if someone really wishes to obtain information it will be very difficult to mstop them especially if he/she is your colleague.\nGood Luck.

The determining factor which makes a UPS (Uninterruptible Power Supply) suitable for a laser printer is the UPS Ratings.  Remember to protect your computer too because your laser printer will be rendered inneffective if you're computer is not working or has no power.\n\nCheck the packaging and see how the ratings are for the following:\n\n1. UL Rating: This is the Underwriters Laboratory test rating of approval for the device. The common rating for surge protectors is UL 1440 or higher. If the device you are looking at does not meet this specification, look for another device.\n \n2. Response Time: This is the time it takes for the device to react to a surge or power outage. Ten nanoseconds or less is the recommended time.\n\n3. Clamping Voltage: This is the point of protection where the device starts to function and senses when something is happening within the electrical circuits. The lower the voltage the better, usually 400 or less.\n \nThree way protection and extra jacks: This should be a given with today’s technology. For the surge protector to work, a 3-wire AC power connection must be used. "Cheater" adapters, which allow 3-wire appliances to be used with 2-wire outlets or extension cords, defeat the electrical ground connection and render most surge suppressors ineffective.\n\nRemember, being prepared for the disaster sometimes helps later on in the recovery. Do not forget to consistently backup your system. Have current data and files stored where you can recover them in case of a system failure. Always use a UPS to protect your computer not just your laser printer.

If you are lucky, you won't have any problems.  BUT, and it's a big BUT, often if you lose power for even a second or two while your computer is engaged in something like a defragmentation process, you can really louse up the File Allocation Table or other processes, and be unable to recover from it without completely reformatting your hard drive and re-installing Windows and your other programs.  My advice to you, if you live in an area where you have frequent power glitches is to buy yourself an Uninterruptible Power Supply (UPS).  This device gets plugged into the wall socket, and your computer gets plugged into the battery backup outlet on the UPS.  If the power fails, your UPS instantly switches so that the battery feeds regular 110V power to your computer so that it continues operating normally.  Depending on the strength of the battery backup, it can provide that power for quite some time, and at least gives you the opportunity to shut down the computer normally if the power loss continues for some time.  \n     To read more about a UPS, go to the link below and read the FAQ's there.\nGood luck.

You should be ok if you have it on a hard surface like a desk or table. \n\nIf you have it on the floor, or couch, or table with tablecloth, it may overheat due to the fan being blocked by the fabric.  Overheating is bad as it can kill the motherboard and/or drive and you would have an expensive paperweight.\n\nLeaving a computer on is supposed to be good for it since booting from the off state over and over adds wear and tear to the system.  I have a PC that I power off every night, and a work laptop that gets shut down once or twice a day, both work fine.  I haven't rebooted my mac in over a month and it too works fine.

Depending upon the frequency on how much you turn it on and off in a given time. The newer PCs motherboard does not completely shut down, but goes on deep standby mode, much of the power, even just a trickle, is applied under this condition through the boot sensing channels handled by the bios and accompanying chipsets and sub circuitry without supplying power to the major areas until needed, including the main CPU. any abrupt powering on and off may contribute some possibility of failure, but not necessarily immediate, and may take some time to evidence itself. The switching mechanisms had changed from basic mechanical to digital pulse actuated SCR transistors that are quite susceptible to voltage spikes. The most concern will be noted at the power junction between the power unit and the power interface circuitry on the motherboard. On these aspect much consideration really rely on the quality of what these components are made, and how the circuitry is designed entirely. Therefore, the quality of the components may have a real bearing on the possibility of any failure by repeatedly turning your PC on or off, that could cause a voltage spike at each transition.\n~meow
