Do I need an UPS for my personall computer?

No, you really don't need a UPS.  Some people do, but I don't think that you do.  You do, however, need a surge protector.  No computer should ever even be plugged in, without a surge protector.  You also shouldn't use your PC while there are storms that have lightning in your area, whether you have a UPS or not.\n\nJust turn off your PC, and unplug your surge protector from the outlet, if a thunderstorm comes into your area, or if you are going out of town.  Both your PC and your surge protector will last for years, if you do.  If you don't unplug your surge protector that way, you should replace it every 12-18 months.

Just be sure that you are not overloading the UPS. Check the rating on it!

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.

Hey.. you need to check the battery of the UPS, as it got week. When the power off, Normally the output of UPS is depend up on the source of battery power inside. when power exists then, it keeps on charging and holds it with average voltage of 12.0 + - 5.0, but when power off, then the charging section will be off, leading the voltage of the battery reduced to 11.5 + - 5.0, if the battery is good condition. if it is in bad condition then, the battery power would be below to 9.0 volts. in such situation the out put will be stoped for a while and the modem gets disconnected as power gets off for a while that is 1.2 secs. The PC will continuesly work without shut down. so you need to change the battery of the UPS or have a Advanced technology API UPS so it have low voltage fecility to rum the UPS. hope it works with you.. all the best.

You do not need it. Hewlett Packard installs it whether you like it or not, whenever you buy one of their machines. I usually reformat the hard drives on them and reinstall Windows Xp from a Microsoft CD whenever I get a HP (or a Compaq), as it irritates the crap out of me, as well. Dell used to do that stuff, too, but they're getting better these days.

It would depend on the drive.  All information will be located on the box.  If you are not sure, bring a copy of what your computer has and bring it somewhere like Circuit City.  The sales people should be able to find one that will fit your system.

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 they are. It keeps the "professional image" of the UPS. Here is an article that was written about it: http://www.cnn.com/US/9708/15/ups.culture/

you need an air card.  Then you can pick up signals or get your own internet and take your computer to anyroom or outside without limitations and tangels of cords.

UPS means Uninterrupted Power Supply. Based on the working principle, It is being classified into 2 types namely On-Line UPS and Off-Line UPS.\n\nOn-Line UPS\n\n                In this type of UPS, The Commercial AC supply is fed to an invertor and converted in DC supply and the battery gets charged. Output is taken from the battery, fed to an invertor and again converterd into AC supply. Here always the output is derived from the battery even if the commercial supply is available.\n\nOff-Line UPS\n \n                 In this type of UPS, the commercial supply is directly connected to the output and also to the battery charger through invertor. There is a relay to switch over from directly supply to the battery.  When there is a power failure occurs, the relay automatically connects to the battery and now the battery get draining. Here there will be a delay in terms of micro seconds which will not make any significance. \n\nOnline UPS can be used for critical places where the system is sensitive for micro seconds power failure. The Online UPS is costlier than Off-line UPS.

I think it's worth it - a surge protector or even a UPS. Sometimes you can get deals on free power strips with surge protection. A UPS will only cost $30-$50 bucks at most, I think.
