FAQ of the Week
Question:

What is the origin of the Bluetooth name?

Answer:

The Bluetooth SIG adopted the name in honor of the tenth-century Vicking king Harold Blatand (Bl�tand) nicknamed King Harold Bluetooth. He is known for uniting Denmark and Norway (the Bluetooth technology was invented in now Swedish Scania -- Denmark). Likewise, Bluetooth is intended to unify different technologies including computers and phones. The Bluetooth logo merges the Nordic runes analogous to the modern Latin H and B.

 Tip of the Week
Tip:

To extend the life of your battery, at least twice a year, drain it completely and then charge it for 14 hours.

To drain it completely, you need to temporarily turn off your computer's battery alarms and leave the computer on until it turns off because of a lack of power. Then charge it for a solid 14 hours.

To turn off battery alarms in Windows XP, uncheck the "Low Battery Alarm" and "Critical Battery Alarm" on the Alarms tab of the Power Options Properities page. (To display the Power Options Properties, right click on your desktop, select Properties. From the Screen Saver tab, select the Power button, then select the Alarms tab.)
