We had bunch of these come into my work. I purchased one to bring home. Before hand i had plugged it into a monitor at work and it came on just fine. Brought it home and just got to plugging it in to reinstall a new copy of windows and no video will show. I tried the VGA and the Display port. It is not the cables nor the monitor. I removed battery to clear CMOS and tried again, still nothing. As soon as i plug the power cord into it, it turns on before i can even hit the power button though which i have seen other pcs in the past do. Anyone know these computers if they have a known issue that may cause this? I should state im only working with onboard video as well.
