Replacing Gateway M305 Components Preparing your work space Before performing maintenance on the notebook, make sure that your work space and the notebook are correctly prepared. 4 ■ Wear a grounding (ESD) wrist strap, and use a grounded or dissipative work mat. ■ Use a stable and strong table, and make sure that the table top is large enough to hold each component as you remove it. ■ Use bright lighting to make part identification easier.
Preventing static electricity discharge Preventing static electricity discharge The components inside the notebook are extremely sensitive to static electricity, also known as electrostatic discharge (ESD). Warning ESD can permanently damage electrostatic discharge-sensitive components in the notebook. Prevent ESD damage by following ESD guidelines every time you open the notebook case.
Replacing Gateway M305 Components Before working with notebook components, follow these guidelines: ■ Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam. ■ Remove components from their antistatic bags only when you are ready to use them. Do not lay components on the outside of antistatic bags because only the inside of the bags provide electrostatic protection. ■ Always hold components by their edges. Avoid touching the edge connectors.
