Steps in installing a new hard drive

Unplug all cables and remove the battery from your laptop. Also remove any PC cards. Flip the computer upside down and set it on a flat surface. To avoid damaging the top of the computer, use a lint free towel as a stabilizer.

Unscrew the hard drive screws and set them aside. Slide the hard drive memory out and place it in an anti-static package. Remove the new drive from its anti-static packaging and carefully slide it into the hard drive bay. Once it is fully inserted, replace the hard drive screws. When the computer reboots, it should recognize the new memory automatically. The entire process takes only a few minutes.

Installing the components like contact sensor and the keypad

The next component to install is the contact sensor. These sensors should be installed in those areas within a home through which an intruder is expected to pass. Once again this decision has to be taken by the house owner. He should select a place that is close to the entry or exit point, and would invariably pick up any motion.

Finally, the house owner needs to install the keypad. This device should be installed near the entry door to enable the house owner to arm or disarm the alarm with ease. A house owner can add light motion-sensor lights around the home. These lights should switch on whenever an individual passes underneath them.

A similar procedure is to be followed in the case of a hard-wired alarm. The only difference is that all the components of the alarm system have to be connected by electrical wiring. Since this wiring should be concealed, the house owner has to make an extra effort to install the alarm system.
