My Latitude has been having an intermittent issue recently when waking from sleep. When I open the lid and press the power button to wake it up, the power light comes on, and so does the caps lock light, but the screen will not come on, or even wake up at all. When I hold the power button to shut it off, no response. I have to remove the battery. When I power it back on, same issue. There is no BIOS screen or any activity. The only way to get it to work is to re-seat the RAM.
