Table A-4 Power supply specification Manufacturer Regulatory model number Lite-on TPN-LA15 Delta TPN-DA16 Power supply rating 19 V dc /2.31 A - 45 W 19 V dc /2.31 A - 45 W Energy saver feature This monitor supports a reduced power state. The reduced power state is initiated if the monitor detects the absence of either the horizontal sync signal or the vertical sync signal. Upon detecting the absence of these signals, the monitor screen is blank, the backlight is turned off, and the power light turns amber. In the reduced power state, the monitor uses < 0.5 W of power. There is a brief warm-up period before the monitor returns to its normal operating state. See the computer manual for instructions on setting the energy saver mode (sometimes called "power management feature"). NOTE: This power saver feature works only when the monitor is connected to a computer that has energysaver features. By selecting the settings in the monitor Sleep Timer utility, you can also program the monitor to initiate the reduced power state at a predetermined time. When the monitor Sleep Timer utility initiates the reduced power state, the power light blinks amber. 18 Appendix A Technical specifications
