to install the driver before connecting. Check the documentation provided by
the device’s manufacturer before connecting the device.
Before disconnecting a USB storage device, make sure your computer has
finished transferring data to that device. Click the Safely Remove Hardware
and Eject Media icon in the Windows notification area to remove the device

Replacing the hard disk drive ———————————————–
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.
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. 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.

Replacing memory —————————————————————————
You can increase the amount of memory in your computer by installing double-
data-rate three synchronous dynamic random access memory (DDR3
SDRAM)-available as an option-in the memory slot of your computer. DDR3 SDRAM
is available in various capacities.

incorrectly install optional
memory, or install an unsupported memory type, a warning beep will sound when
you try to start the computer. · Select models of the computer may have only
one memory slot. Refer to the actual product. However, the procedure for
replacing the memory is the same as listed below.
To install DDR3 SDRAM, do the following: 1 Touch a metal table or a grounded
metal object to reduce any static
electricity in your body, which could damage the DDR3 SDRAM. Do not touch the
contact edge of the DDR3 SDRAM. 2 Turn off the computer. Disconnect the AC
power adapter and all cables from the computer. 3 Close the computer display
and turn the computer over. 4 Remove the battery pack. 5 Remove the Optical
