Optical discs can tolerate accumulated dirt and dust much better than floppy disks since CDs are not read by direct contact with the read lens. Excessive dirt, however, will eventually affect the drive's performance. Thoroughly clean the discs whenever necessary. · 62 Bays Hard Disk Drive A hard disk drive (HDD) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. On most systems, it is a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media. The HDD is your notebook's primary storage device, storing all of your system files and installed programs. Therefore, it is also usually your notebook's largest storage device (in today's systems, it is quite common for a single consumer HDD to have capacities of over 100 GB, and desktops tend to have larger capacities than notebooks). Depending on your system configuration, the HDD may be upgraded to a larger capacity drive. Some systems may even have more than one HDD installed. Note Please contact your authorised service representative if you wish to replace your hard disk drive. This procedure should only be performed by a qualified technician. 63 Taking Care of Your Notebook Notebook Care Your notebook is a durable, dependable system built for heavy use. With protective measures and proper care, you can prevent problems and promote the successful operation and long lifespan of your notebook. Protecting Your Notebook From Power Outages Fortunately, there are tools that can help when power supply is interrupted. Basically there are two types of protection against power problems, a passive form such as those provided by surge suppressors and a multi-featured back-up power source like the Uninterruptible Power Supply (UPS). · Surge Suppressors - although computers are equipped with some surge protection, it is wise to acquire a separate surge suppressor for added protection. A surge suppressor protects power supplies and communication lines from electrical surges but does not offer a back-up power source. While some suppressors have a manual on-off switch, other types combine switched and unswitched circuits. A mix of switched and unswitched circuits can be a useful feature since you can keep, for instance, a battery charging while shutting off the power for other equipment. Back-UPS units - equipped with a battery to maintain power during outages, the UPS allows users to save data and properly shut down the notebook. Most UPS also include surge protection as a feature. There are two basic UPS types, the standby power supply (the least expensive choice) and the multi-featured on-line UPS systems. · Below are tips on power protection and some hardware features to consider before buying these devices: · · · Be sure to unplug your notebook, including the line to the modem, during lightning storms. Always use a proper power cord to plug your notebook to the line power.
