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.
• Keep your computer software, device drivers, and operating system up-to-date. See “Keeping your
computer current” on page 56.
• Empty your recycle bin on a regular basis.
• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.
• Clean up files and free up storage drive space and memory space occasionally to prevent performance
problems. See “Performance problems” on page 75.
• 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 determine the cause of a problem.
