ABSTRACT:
A portable computer having a standby power mode of operation has a bay for receiving a portable removable disk drive. The drive has a pair of slots engageable with parallel guide rails in the receiver, and a notch engageable with a retractable latch normally biased in the direction of the notch. A switch adjacent one of the rails generates a standby signal for the computer whenever the drive is inserted into the bay or moved in the ejection direction after installation. An ejector mechanism retracts the latch and an auxiliary locking pivot to release the drive for removal. The ejector also provides an ejection force which moves the drive a sufficient distance externally of the bay to permit the drive to be grasped by the user for complete removal. A grounding contact engageable with a similar contact on the drive provides a static discharge path for the drive prior to electrical interconnection with the computer.
