Abstract: A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program. It can be learnt from above that, the terminal can determine, according to a variation in light intensities, whether the terminal is blocked by clothes, and close the target program. This reduces running power consumption of the terminal and increases a standby time of the terminal.

Abstract: A data storage device is disclosed comprising a disk, a head comprising a touchdown sensor, and a fly height actuator (FHA) configured to actuate the head vertically over the disk based on an FHA setting. The data storage device is configured into a read mode, and while in the read mode, the FHA setting is adjusted until the head contacts the disk and a touchdown read mode resistance of the touchdown sensor is measured. The data storage device is configured into a write mode and the FHA setting is adjusted so the head is not contacting the disk. While in the write mode, a non-touchdown write mode resistance of the touchdown sensor is measured, and a write touchdown FHA setting that will cause the head to contact the disk while in the write mode is estimated based on the touchdown read mode resistance and the non-touchdown write mode resistance.
