• Keep electrical appliances such as an electric fan, radio, high-powered speakers, air conditioner, and
microwave oven away from your computer because the strong magnetic fields generated by these
appliances can damage the monitor and data on the storage drive.
• Keep food and drinks away from all parts of the computer. Food particles and spills might make the
keyboard and mouse stick and unusable.
• Do not get the power switches or other controls wet. Moisture can damage these parts and cause an
electrical hazard.
• Always disconnect a power cord by grasping the plug instead of the cord.
• Keep the computer software, device drivers, and operating system up-to-date.
• 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.
• 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.
• Back up your data on the storage drive regularly. You can restore the storage drive from a backup.
• Create a recovery medium as early as possible. You can use the recovery medium to recover your
operating system.
• Get the most up-to-date operating system update patches, software programs, and device drivers.
Maintenance tips about moving the computer
Before moving the computer, take the following precautions:
1. Back up your data on the storage drive.
2. Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
3. If you saved the original shipping cartons and packing materials, use them to pack the units. If you are
using different cartons, cushion the units to avoid damage.
When you move the computer to another country or region, you must take local electrical standards into
consideration. If the local electrical outlet style is different from the type you are currently using, contact the
Lenovo Customer Support Center to purchase either an electrical plug adapter or a new power cord.
Clean your computer
CAUTION:
Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
Clean the computer surface: Wipe it with a lint-free cloth dampened in mild soap and water. Avoid applying
liquids directly to the surface.
Clean the keyboard: Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If
you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid
