Take the output voltage and current listed on the label and multiply them. That is, "Output 24V" x "1.04A" = 25 Watts. Your Lombard will want 1.7 Amps or more at 24 volts. Otherwise, the power supply may collapse when the hard drive tries to spin up or at some other power-hungry part of the boot process. If that 45VA is output power, it's enough. If it's referring to 50/60 Hz AC input, the adapter is probably too small.

Of course there may be something else wrong as well, but make sure you have the right power adapter first. You can boot a Lombard off of a 36 Watt (1.5A) Duo adapter if the Lombard has a good battery to help out.
