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
or in sleep 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.
• Do not touch the connector.
