Chapter 4. Troubleshooting

A hard disk drive problem

The hard disk drive does

not work.

• In the Startup menu in the BIOS setup utility, make

sure that the hard disk drive is included in the Boot

Priority Order list.

Other problems

Your computer does not

respond.

• To turn off your computer, press and hold the power

does not respond, remove the battery pack and the

AC power adapter.

• Your computer might lock when it enters sleep mode

during a communication operation. Disable the sleep

timer when you are working on the network.

The computer does not

start from a device you

want.

• See the Boot Priority Order list of the BIOS setup

utility. Make sure that the BIOS setup utility is set so

that the computer starts from the device you want.

computer starts is enabled. Make sure that the device

is included in the Boot Priority Order list in the BIOS

setup utility correctly.

• Press F12 when the Lenovo logo appears on the

device you want the computer starts from.

The connected external

device does not work.

• Do not connect or disconnect any external device

cables other than USB while the computer power is

on; otherwise, you might damage your computer.

• When using a high power consumption external

device such as an external USB optical disk drive, use

an external device power adapter. Otherwise, the

device may not be recognized, or system shut down

may result.
