Chapter 6. Safety, use, and care information
Take care in setting passwords
Remember your passwords. If you forget a supervisor or hard disk
password, Lenovo authorized service providers will not reset it, and you
might have to replace your main board or hard disk drive.
Other important tips
Your computer has an Ethernet connector. Be sure to connect your
communication cable to the correct one, so your connector is not
damaged.
Register your Lenovo products with Lenovo (refer to the Web page:
http://consumersupport.lenovo.com). This can help authorities return your
computer to you if it is lost or stolen. Registering your computer also enables
Lenovo to notify you about possible technical information and upgrades.
Only an authorized Lenovo repair technician should disassemble and
repair your computer.
Do not modify or tape the latches to keep the display open or closed.
Take care not to turn your computer over while the AC adapter is
plugged in. This could break the adapter plug.
Turn off your computer if you are replacing a device, or else verify that
the device is warm- or hot-swappable.
Before you install any of the following devices, touch a metal table or a
grounded metal object. This action reduces any static electricity from
your body. The static electricity could damage the device.
