The Laptop is HP Compaq Model Presario CQ57. Cannot be charged owing to cutting off of power. I checked turn-off to the plug and cable before the transformer/power converter part of electrical supply. That small section tripped the ECLB so I decided to cut off the sealed plug and rewired a replacement. This also cut-off power. Logically it must be the wiring inside the cable from plug to that same juncture.
I will not have access to this other computer until tomorrow evening/night.
