Having Bluetooth has nothing to do with having a liking for all things blue. In fact, it is a standard of communication that empowers your computer to do a lot more. Here are 5 things you need to know about Bluetooth for your computer.
1) It’s Wireless: Your personal computer will no longer need to have a million and one wires coming out of it and spreading all over the place. Bluetooth makes your computer wireless. Everything from your mouse, keyboard and printer to your digital camera can now connect to your PC wirelessly!
2) Range Devices: Bluetooth is basically a range device. Your various computer peripherals need to have Bluetooth connectivity and should be within range of your PC. Usually all devices within a room are Bluetooth connectable.
3) Accessories: No need now to find a suitable cord to connect your mobile or camera to your PC. Just get your Bluetooth phone into the room and voila! It immediately gets detected!
4) Transfer Without Hassles: Transfer of data was never easier. You can transfer data from one device to another by the click of a button. No need to install any software, connect cables etc. Syncing your PDA with a computer just takes a simple click while you are in the same room as your computer.
5) Security: What you do need to be a bit careful about though is the security. If you have not set the security settings on your PC properly, any other person can access personal data easily. Always understand the security features well before turning on your Bluetooth.

There you are! So now get ready to enjoy your home PC in a new and improved avatar!


The hard disk goes through thermal stress each time the PC is turned off and on. The hard disk in your PC uses up incredibly little electricity when it is in an inactive state. You may feel that you’re increasing your power costs by keeping your PC on, but remember that’s better than dealing with hard disk crashes --- and the consequent loss of data --- as a result of switching your machine off and on too many times. You are better off leaving your PC on than trying to save electricity and turning it off several times in a day. So reduce the number of times you turn your PC on and off

In the past we have told you that you can protect your hard disk by limiting the number of times you turn the PC on and off during the day since each time you do this the hard disk goes through thermal stress. However you should turn off just the monitor when it’s not going to be in use for more than a couple of hours. This will help make the monitor last longer because the CRT (cathode ray tube that makes up most of the monitor) lifespan is limited and related to the number of hours it is left on. Moreover remember that most monitors consume as much power as the PC itself. So even while you are protecting the hard disk by leaving the PC on, you can protect the monitor plus save power by turning just the monitor off. Since monitors take just a couple of seconds to display, there isn’t even an issue of `waiting’ as in the case of a PC which takes a few minutes to boot every time you turn it on.

You would have noticed that the top of your monitor has ventilation, that’s because monitors like your PC get heated up when in use. To extend the life of your monitor (and your television set, whether you are watching channels or using the TV as a PC) be sure that you do not place anything on the monitor.
Crashing Components? Try these

Sometimes what seems like a disaster in the PC's system may actually be a minor problem. However, there will be times when you must bite the bullet and either repair or replace an expensive component. What you do depends on several factors, including the relative age and value of the damaged components and the prospect of actually repairing it. If you do need repair help, you have several choices:

• If the component came with a system that is under warranty, contact the vendor for service. Often you will be able to avoid the cost of repair and will simply receive a new replacement part directly from the system manufacturer.
• If you brought the component separately, check its warranty. If it is still covered, contact the manufacturer.
• If you purchased a new peripheral or system and it failed to work (called 'dead on arrival' or DOA) you should be able to return it for a new part, or a full refund!

Out of warranty repairs can be conducted by technicians at your local computer store, ranging from single store garage shops to regional and national chains.
