„Introduction  
The Lenovo OneKey Rescue system is an easy-to-use application that can be 
used to back up the data on your system partition (C drive) for easy restore 
when required. You can run Lenovo OneKey Recovery under the Windows 
operating system, and the OneKey Rescue system without starting the 
Windows operating system.
Attention:
In order to utilize the features of the OneKey Rescue system, your hard disk 
already includes a hidden partition by default to store the system image file 
and OneKey Rescue system program files. This default partition is hidden 
for security reasons and is the reason the available disk space is less than it 
claims. The exact available hard disk space depends on the file size of the 
mirror image file (based on the size of operating system and preinstalled 
software).
„Using Lenovo OneKey Recovery (within Windows operating 
system)
In Windows operating system, double click the OneKey Recovery system 
Icon on the desktop to launch Lenovo OneKey Recovery. 
Within the program, you can back up the system partition on the hard disk 
drive, other storage devices, or by creating recovery discs. 
For more instructions, see the Help file of Lenovo OneKey Recovery.
Notes:
The backup process and creation of recovery discs may take some time, connect the AC 
adapter and battery pack to your computer.
After the recovery discs are burned, please number them so that you can use them in the 
correct order.
Computers without an integrated optical drive support the creation of recovery discs; 
however an appropriate external optical drive is needed to physically create the recovery 
discs.

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 perma-
nent 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 com-
puter 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. 
Do not touch the connector.

You can increase the amount of memory in your computer by installing a 
double data rate (DDR3) small outline dual inline memory module (SO-
DIMM)-available as an option-in the memory slot of your computer. SO-
DIMMs are available in various capacities.
 To install an SO-DIMM, do the following: 
1Touch a metal table or a grounded metal object to reduce any static elec-
tricity in your body, which could damage the SO-DIMM. Do not touch 
the contact edge of the SO-DIMM. 
2Turn off the computer. Disconnect the AC adapter and all cables from the 
computer.
3Close the computer display, and turn the computer over. 
4Remove the battery again.
