incorrect.

The real-time clock (RTC) battery may need to be replaced. Battery life is approximately

seven years.

Before replacing the battery, try resetting the date and time in your operating system by

using the Control Panel. If the problem persists, replace the battery. See the Upgrading

and Servicing Guide for replacement instructions.

Symptom Possible solution

If you created multiple user accounts on your PC, make sure other users are not logged

in. If there are multiple users logged in at one time, system resources must be shared

among the multiple users.

Run the Disk Cleanup program to delete unwanted files (including temporary Internet

files, installed components and programs that you no longer use, and files in the Recycle

Bin) from your hard disk drive:

1 Click Start, All Programs, Accessories, System Tools, and then click Disk

Cleanup.

2 Select the drive on which you want to perform the cleanup.

3 Choose the files to delete by placing a check mark in the check box next to the file

types listed.

4 Click OK, and then click Yes to permanently delete the files.

Run the Disk Defragmenter program to group fragmented files together on your hard disk

drive and improve performance. This does not affect the location of files and folders on

your PC.

NOTE: The Disk Defragmenter program may take a long time to complete. It is a good

idea to run it overnight.

To run the Disk Defragmenter program:

1 Open the Windows Task Manager by pressing the Ctrl key, the Alt key, and the

Delete key at the same time.

2 On the Applications tab, select all the programs that are listed, and then click End

Task.

3 Click Start, choose All Programs, Accessories, System Tools, and then click

Disk Defragmenter.

4 In the Volume column, select the hard disk drive you want to defragment (typically C:),

and then click Defragment.

Applications and files take

longer to open or respond.

Remove unused programs:

1 Click Start, and then click Control Panel.

2 Double-click the Add or Remove Programs icon. The Add or Remove Programs

window opens.

3 Select the program you wish to remove and click the Change/Remove or the

Remove button.

Follow the onscreen instructions.
