To determine if problems are caused by newly installed software, verify that:

–

Your computer has the minimum memory requirements needed to use the software. See the

information supplied with the software to verify memory requirements. (If you just installed an adapter

or memory, you might have a memory-address conﬂict.)

–

The software is designed to operate on your computer.

–

Other software works on your computer.

–

The software you are using works correctly on another computer.

•

If you received any error messages while using the software program, see the printed documentation

supplied with the software or the help system for that software for a description of the messages and

solutions to the problem.

•

Check with your software manufacturer to see if any updates are available. Many software manufacturers

make updates available from the World Wide Web.

•

If the software program used to work correctly, but does not work correctly now, do the following:

On the Windows 7 operating system, click

Start

➙

Control Panel

➙

.

•

If you are unable to resolve the problem through other methods, uninstall the software program and

reinstall it.

If these actions do not correct the problem, you might need technical assistance. Contact your software

manufacturer or see Chapter 11 “Getting information, help, and service” on page 73 for details.

USB problems

Symptom: The USB connectors cannot be accessed.

Actions:

•

Make sure the USB cable is securely connected to the USB connector and to the USB device. If the USB

device has its own power cord, make sure it is attached to a properly grounded electrical outlet.

•

If the USB device has its own On/Off switch, make sure it is in the On position.

•

If the USB device has an Online switch, make sure it is in the Online position.

•

If the USB device is a printer, make sure paper is loaded correctly.

•

Make sure any device drivers or other software supplied with the USB device is correctly installed.

Refer to the documentation for the USB device.

•

Reset the device by detaching and reattaching the USB connector.

If these actions do not correct the problem, run the diagnostic programs to test the USB connector (see

“Lenovo Solution Center” on page 71 for instructions). If the USB device came with its own diagnostics,

run those diagnostics against the USB device. If you need technical assistance, see Chapter 11 “Getting

information, help, and service” on page 73.

Lenovo Solution Center

The Lenovo Solution Center program enables you to troubleshoot and resolve computer problems. It

combines diagnostic tests, system information collection, security status, and support information, along

with hints and tips for maximum system performance.

Notes:

•

The Lenovo Solution Center program is available only on models preinstalled with the Windows 7

operating system. It also can be downloaded from http://www.lenovo.com/diagnose.
