I opened laptop to resume work. It began to 'waken' from sleep state, but I closed 'lid' again before it had fully wakened. Monitor is now blank/black, and laptop is unresponsive to any input, even though power is still indicated as 'on'. Cannot shut down, as power button is nonresponsive. I removed AC power cord, with no change.
Should I remove battery, discharge power button, then reinsert battery and AC cord and power up again?

Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer into the sleep state is like pausing a DVD player-the computer immediately stops what it's doing and is ready to start again when you want to resume working.
When a computer is in Sleep mode, the power light is blinking and you get a blank screen like it's turned OFF.
On most computers, you can resume working by pressing your computer's power button. However, not all computers are the same. You might be able to wake your computer by pressing any key on the keyboard, clicking a mouse button, or opening the lid on a laptop. Check the documentation that came with your computer or go to the manufacturer's website.
Try turning off, and unplugging the monitor.
then replace the cable between monitor and pc.
if you still get no action, i,d suggest looking at the graphics card.
if it,s a pci card, try it in a different slot on the motherboard.
if it,s agp try an alternative card, if it,s onboard, try adding an additional card to the system, to see if that brings the monitor out of standby.
