General tips for preventing problems

1.Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too full, Windows will slow down and might produce errors.

Note: In Windows 7 and Windows Vista, click Start ➙ Computer. In Windows XP, click Start ➙ My Computer.

2.Empty your recycle bin on a regular basis.

3.Use disk defragment tool regularly on your hard disk drive to improve data seek and read times.

4.To free up disk space, uninstall unused application programs.

Note: You might also want to look for application program duplication or overlapping versions.

5.Clean out your Inbox, Sent, and Trash folders from your e-mail client program.

6.At least once a week, make a point to back up your data. If critical data is present, it is a good idea to perform a daily backup. Lenovo has many backup options available for your computer. Rewritable optical drives are available for most machines and are easily installed.

7.Use or schedule System Restore to take a system snapshot periodically. For more information about System Restore, see Chapter 5 “Recovery overview” on page 111.

8.Update device drivers and UEFI BIOS when needed.

9.Profile your machine at http://support.lenovo.com to keep up to date with current drivers and revisions.

10.Keep up to date for device drivers on other non-Lenovo hardware. You might want to read the device driver information release notes prior to updating for compatibility or known issues.

11.Keep a log book. Entries might include major hardware or software changes, driver updates, minor issues you have experienced and how you resolved them.

12.If you ever need to run a recovery on your computer to return the preload onto the machine, the following tips might help along the way:

•Remove all external devices such as the printer, keyboard, etc.

•Make sure that your battery is charged and that you have the ac power connected.

•Boot into the ThinkPad Setup and load the default settings.

•Restart the machine and start the recovery.

•If your machine uses discs as the recovery media, DO NOT remove the disc from the drive until prompted to do so.

13.For suspected hard disk drive issues, refer to “Diagnosing problems” on page 227 to run a diagnostic test of the drive before you call the Customer Support Center. If your computer does not start up, download the files to create a bootable self-test media from the following Web site: http://www.lenovo.com/hddtest. Run the test and record any messages or error codes. If the test returns any failing error codes or messages, call the Customer Support Center with the codes or messages and the computer in front of you. A technician will assist you further.
