RE: Inspiron 560 boots to power save mode
Green LED on the back has nothing to do with the motherboard battery. So if you haven't changed it in a while, you may want to install a fresh CR2032 3-volt coin cell battery, ~$2 at discount stores, if nothing else than to rule it out as part of the problem.
Monitor going into Power Saving mode usually means it's not getting a video signal from the PC. And since you tried a different monitor and if there's no card in the PCI-e x16 slot, then this isn't a "video card" issue.
Without a PCi-e x16 card, you're using Intel Graphics that are on the CPU. Which onboard video port are you using, VGA or HDMI? If your monitor supports both of those, get a suitable video cable and connect it to that other port on both PC and monitor.
If using a different onboard video port doesn't help, installing a PCi-e x16 video card might (or not) help. So can you borrow one from another PC, at least to test in the 560?
