The term "reseating" refers to the process of removing (or partially removing) a component from its connector or socket before reinserting the part in its original place.

A poor connection at a socket or connector is a common cause of failure in computer equipment, especially if the equipment is old or has been left unused for long periods. For this reason, and because the process is quick and easy to perform, reseating is often the first step in troubleshooting a defective computer. It is often enough to restore a system to working condition: loose connections can be remedied by the simple action of pushing the component fully ?home?. If corrosion has caused the build-up of minor deposits on the part or its connector these may be broken down by the reseating process, restoring the connection. In case of extensive corrosion, visible as a dull layer of oxide on metal parts, the pins can be cleaned up using a mild abrasive (such as Scotch-Brite or very fine sand paper) before reinsertion.
It is not strictly necessary to remove a component entirely in order to reseat it. Often only partially removing the part - enough to disturb any oxide that may have formed ? and pushing it back home is sufficient to revive a poor connection. This method reduces the risk of bending or otherwise damaging connectors or pins.
