You can increase the storage capacity of your computer by replacing the hard disk drive with 
one of greater capacity. You can purchase a new hard disk drive from your reseller or Lenovo 
marketing representative.
The drive is very sensitive. Incorrect handling can cause damage and permanent loss of data on 
the hard disk. Before removing the hard disk drive, make a backup copy of all the information 
on the hard disk, and then turn the computer off. Never remove the drive while the system is 
operating, in sleep mode, or in hibernation mode. 
Notes:
Replace the hard disk drive only if you upgrade it or  have it repaired. The connectors and bay of the hard 
disk drive were not designed for frequent changes, or drive swapping.
 The preinstalled softwares are not included on an optional hard disk drive.
Handling a hard disk drive
Do not drop the drive or subject it to physical shocks. Put the drive on a material, such as 
soft cloth, that absorbs the physical shock.
 Do not apply pressure to the cover of the drive.
