There are five voltage identification pins/balls on the mobile Intel® Celeron® processor connector. These pins can be used to support automatic selection of power supply voltages. These pins are not signals, but are either an open circuit or a short circuit to Vss on the processor. The combination of opens and shorts defines the voltage required by the processor core. The VID pins are needed to cleanly support voltage specification variations on mobile Intel Celeron processors.
These pins (VID[0] through VID[4]) are defined in the table below. A '1' in this table refers to an open pin and a '0' refers to a short to ground. The power supply must supply the voltage that is requested or disable itself. To ensure the system is ready for current and future mobile Intel Celeron processors, the range of values in bold in the table below must be supported. If your motherboard provides a smaller voltage range than those listed, it may not be able to support all members of the mobile Intel Celeron processor family.
Note: this table is different than the desktop Intel Celeron processor.
