Explanation of Hard Disk CapacityDear user,While using your computer, you may discover that the nominal hard diskcapacity indicated is somewhat different from the disk capacitydisplayed by the operating system. For example, a nominal 80GB harddisk will appear as less than 80GB in the operating system. Thisdiscrepancy is not an error in hard disk installation nor any otherproblem, but a normal phenomenon of computers. This phenomenon isprimarily due to the following reasons:I. Different standards used by the manufacturer and operatingsystem when calculating hard disk capacityHard disk manufacturers use a radix of 1000, i.e. 1G = 1,000MB, 1MB =1,000KB, 1KB = 1,000 bytes. However, when identifying hard disk capacity,operating systems use a radix of 1024, i.e. 1GB = 1,024MB, 1MB = 1,024KB,1KB = 1,024 bytes. The standard adopted by your computer is that of thehard disk manufacturers. Since the standards adopted by the hard diskmanufacturer and operating system are different, the hard disk capacitydisplayed by the operating system will be different from the nominal harddisk capacity.For example, if the hard disk is nominally X G, even when it is completelyempty, the capacity displayed by the operating system will be:X × 1000 × 1000 × 1000/ (1024 × 1024 × 1024) | X × 0.931 GS9-S10 User Guide V1.0_en.book Page 3 Wednesday, July 23, 2008 5:53 PM
If a portion of the hard disk space has been used for some specific purpose,then the capacity indicated by the operating system will be even less thanX × 0.931 G.II. A portion of the hard disk space is used for specific purposesLenovo computers come with preinstalled OneKey Rescue System, so thehard disk has a special portion partitioned before delivery, which is used tostore hard disk mirror and OneKey Rescue System program files. The sizeof the reserved space for this partition varies according to the model,operating system and software of the computer. For the sake of safety, thispartition is not evident, which is commonly referred to as a “hiddenpartition”.In addition, after the hard disk is partitioned or formatted, the system willassign a certain amount of hard disk space for the system files.For the above reasons, the available hard disk space indicated by theoperating system is always less than the computer’s nominal hard diskcapacity.S9-S10 User Guide V1.0_en.book Page 4 Wednesday, July 23, 2008 5:53 PM

26Chapter 2. Using Your ComputerChecking Battery StatusYou can determine the percentage of battery power remaining by usingWindows Power options.The rate at which you use battery power determines how long you can usethe battery of your computer between charges. As each computer user hasdifferent habits and needs, it is difficult to predict how long a batterycharge will last. There are two main factors:The amount of energy stored in the battery when you begin to work.The way you use your computer: for example, how often you access thehard disk drive and how bright you make the computer display.Using the AC AdapterThe power to run your computer can come either from the lithium-ion (Li-ion) battery pack provided with it, or from AC power through the ACadapter. While you use AC power, the battery charges automatically.The AC adapter that comes with your computer has two basic components:1The transformer pack that converts AC power for use with the computer.2The power cord that plugs into the AC outlet and into the transformer pack.Attention:Using an improper power cord could cause severe damage to your computer.To use the AC adapter, do the following.
