Good maintenance practices
By performing a few good maintenance practices, you can maintain good computer performance, protect
your data, and be prepared in case of a computer failure.
• Empty your recycle bin on a regular basis.
• Use the disk defragmentation or disk optimization feature of your operating system occasionally to
prevent performance problems caused by an excessive number of fragmented files.
• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.
• Back up critical data regularly on removable media memory, such as discs and USB storage devices, and
store the removable media in a safe location. The frequency of making backup copies depends on how
critical the data is to you or your business.
• Back up your data on the storage drive regularly. See “Recovery information” on page 59.
• Keep your computer software, device drivers, and operating system up-to-date. See “Keeping your
computer current” on page 26.
• Keep a log book. Entries might include major software or hardware changes, device-driver updates,
intermittent problems and what you did to resolve them, and other issues you might have experienced.
The cause of a problem might be change in hardware, change in software, or any other actions that might
have taken place. A log book can help you or a Lenovo technician determines the cause of a problem.
• Create Product Recovery discs. See “Recovery information” on page 59 for more information about using
Product Recovery discs to restore the hard disk drive to the factory-default settings.
