Hi Sheldon,

I'm not sure I can be of much assistance here but WPU are only available when the TRIS-bit is set. That is, when the pin is an output (TRIS-bit cleared) the WPU for that pin is disabled. So no, having the WPU enabled on an output pin, when in sleep mode or otherwise, is not normal and not something that should be happening.

However, when entering sleep mode, all the peripherals are turned off (no longer clocked) but outputs that are being driven will be kept 'on' during sleep so any load you have on those outputs will be reflected in the total current drawn by the PIC.
