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