HP ProLiant DL380 G7 servers will not POST
Check your KVM... Try with different keyboard/monitor or run headless. Don't repeat the mistakes made here.

Edit: It would be important to get into the ILO to see server messages. The ILO's settings are persistent, so removing the battery won't help you. Even if your issue is not KVM-related, the rest of the flowchart above should help you isolate the issue.
If you have physical access to the server, you can try this sequence:
- Remove the power supply units and swap them.
Test to see if the system will boot...
If that doesn't work:
- Remove all power supplies from the chassis
- Locate the System Maintenance Switch on the motherboard - It's a set of 10 DIP switches.
- Turn switch #6 switch on.
- Insert all power supply units.
- Power on the server and allow it to idle for 3 minutes.
- Power the server off.
- Remove all power supplies.
- Return DIP switch #6 to off (original) position.
- Reinsert the power supplies.
- Power the server on.
