DANGER: Power Cords and Power Adapters Use only the power cords and power adapters supplied by the product manufacturer. Do not use any power adapter that shows corrosion at the AC input pins and/or shows signs of overheating (such as degraded plastic) at the AC input or anywhere on the power adapter. Do not use any power cords where the input (plug) pins or the output (receptacle) pins show signs of corrosion or overheating or where the power cord appears to have been damaged in any way. Always ensure that all power cord connections are securely and completely plugged into receptacles. Never wrap a power cord around the power adapter or other object. Doing so can cause the cord to fray, crack or crimp. Always route power cords so that they will not be walked on, tripped over, or pinched by objects. Protect the cord and power adapters from liquids. For instance, do not leave your cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a potential short circuit. 44 ThinkPad® R50 Series Service and Troubleshooting Guide
