About NVIDIA® OptimusTM (on select models)

Optimus is a GPU switching mechanism which automatically switches the
active GPU to perform image-rendering tasks. If no graphics-intensive
programs are running, the integrated GPU will be selected as the active GPU
to preserve battery life; if you start high-definition movie playback or a 3D
game, the image-rendering task is automatically switched by Optimus to the
discrete GPU to produce high graphics performance.

When Optimus is enabled, switching between integrated and discrete GPUs
is performed automatically without user intervention.

Chapter 5. Troubleshooting

What can I do if the back-up process fails?

If you can start the backup but it fails during the back-up process, try the
following steps:

1

Close all open programs, and then restart the back-up process.

2

Check to see if the destination media is damaged. If it is, replace the
damaged media. Otherwise, select another destination path and try
again.

When do I need to restore the system to its original factory status?

Use this feature when the operating system fails to start. If you have any
critical data on the computer that you want to save, back it up before
starting the recovery process.

 BIOS setup utility

What is the BIOS setup utility?

The BIOS setup utility is a ROM-based software program. It displays basic
computer information and provides options for setting boot devices,
security, hardware mode, and other user preferences.

How can I start the BIOS setup utility?

To start the BIOS setup utility:

1

Shut down the computer.

2

Press the Novo button and then select BIOS Setup.

How can I change the boot mode?

There are two boot modes: UEFI and Legacy. To change the boot mode,
start the BIOS setup utility and set boot mode to UEFI or Legacy support
on the boot menu.

When do I need to change the boot mode?

The default boot mode for your computer is UEFI mode. If you choose to
install a legacy Windows operating system (that is, any operating system
prior to Windows 8) on your computer, you must change the boot mode to
Legacy support. A legacy Windows operating system cannot be installed
until you change the boot mode.

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.

Note:

• 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.

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

Note:

• Use only the memory types supported by your computer. If you 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 a 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 adapter and all cables from the
computer.

3

Close the computer display, and turn the computer over.
