If you have questions, you can call the company's customer service number and speak with a technician on the telephone. Investigate both local and mail-order sources and buy from the one you feel most comfortable with. Warranty and Extended Service Plans Look for a computer with a warranty that covers manufacturing defects and other problems. Make sure you understand exactly what is covered under the warranty. Most new computers are covered for a year, and some warranties include on-site maintenance.
Many retailers offer extended service agreements which, in essence, lengthen the warranty.
Whether or not you purchase an extended service plan is up to you. Find out what is covered and weigh the price of the warranty against the price of potential repairs. Your computer is an expensive piece of equipment, so protect it from power surges with a surge protector. A surge protector will blow a fuse if it gets hit by a rush of electricity, thus protecting your computer. If you're using a modem, be sure to get a surge protector with a telephone jack included.
