If not, replace it with a working CD/DVD shipped with the computer to check whether it can be read by the computer. 2.The capacity of the hard disk displayed in the system is less than the nominal capacity For equipped with One-Key Recovery feature, the system recovery feature needs to occupy some hard disk space which is invisible in either the operating system or partition utilities such as FDISK, thus the available hard disk space is less than the actual capacity. The nominal capacity of the hard disk uses the decimal system of 1000 bytes, while the actual capacity uses the binary system of 1024 bytes (for example, the nominal capacity 1G = 1000M, while the actual capacity 1G = 1024M); the capacity of the hard disk shown in Windows can be calculated according to the calculation method in the following example: The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000 x1000/ (1024 x 1024 x 1024) = 37G. If the hidden partition of 3G - 3 x 1000 x 1000 x 1000/ (1024 x 1024 x1024) = 2.79G is subtracted, the capacity of the hard disk shown in the system can be obtained. The capacity of the hard disk calculated Lenovo 3000H User Guide 47 with above method may be slightly different from the actual capacity for such reason as rounding. 5.6 Special Description of Windows 1. Keep the serial number of the software shipped with your computer in a safe place The serial number of the software shipped with the computer is provided separately by the manufacturer; keep it in a safe place.
