If your HP Desktop is not responding to the USB keyboard or mouse, the computer may be in standby mode. To resume, press the power button or any key. If the system has locked up, restart the computer.
What to do if my HP Elite 7500 Microtower won't power on?
If your HP Desktop system does not power on and the LEDs are not flashing, press and hold the power button for less than 4 seconds. If the hard drive LED turns green, check that the voltage selector is set correctly for your region. Also, try removing expansion cards one at a time until the 5V_aux light on the system board turns on, or replace the system board. If the hard drive LED does not turn on green, ensure the unit is plugged into a working AC outlet. Open the hood and check that the power button harness and both power supply cables are properly connected to the system board. Check if the 5V_aux light on the system board is on; if it is, replace the power button harness; if it is off, replace the power supply or the system board.
