@ Gopinath - The KDPM module has Wake on LAN feature that you can use to schedule WOL and even alert on it. You have to have the Kaseya Desktop Policy add-on agent module installed on the endpoints to do the alerting on failed WOL events. So you could use this module to do a WOL test on machines after hours and generate a report on all machines that failed to Wake up.
Just a note that since Craig mentioned WOL and vPro that they are very different technologies and should not to be confused with each other.
@ Craig Hart - Most HP business desktops and laptops that has Intel chipset's now supports vPro these days. Sometimes it is not called vPro though and you need to see if there are any Intel AMT drivers available for the machine.
I did a deployment project recently and the DC 7800, 7900, Compaq Elite 8000, 8200 and 8300 all supported vPro. Their HP Elitebook Laptops ranged from 6930p, 8440p, 8460p, 8470p, 8560p and 8570p all supports vPro too so not so rare at all as I have seen the same for other brand machines with Intel chipset motherboards.
