Operating environment

ThinkPad computers are designed, built, and tested for high quality and reliability. When used properly in standard business environments, a ThinkPad a20m system should be a reliable computing asset for many years. However, harsh environments and abuse can damage ThinkPad systems since they are not intended to withstand extreme temperatures, dust, shock, or other severe physical environments. ThinkPad systems should not be used in unsuitable environments. For example, a ThinkPad system should not be used in non-stationary environments, such as in-vehicle installations, without additional casing or shock-dissipation. IBM warrants that the ThinkPad a20m will conform to its Official Published Specifications when used in a suitable physical operating environment.
