A couple of days ago, after leaving my computer on overnight, I checked my email in the morning and then shut it down (or attempted to). When I returned home from work the same day, I went to turn the computer on and realized that the button was glowing orange as it does when it is hibernating (instead of glowing green as it does when "awake"). The power button would not wake up the computer, nor would the mouse or keyboard. I held the power button in to turn the computer off. Now when I turn the computer on, it goes directly into hibernate mode (power button glows orange) and does not attempt to return to Windows ME. It is completely silent and unresponsive, as though the power is off, except that the power is on. I took the back panel off of the computer and verified that all of the cards were firmly in place and not dislodged. I also disconnected everything but keyboard and mouse and nothing changed. Any ideas?
