Absolute maximum is the "don't say we didn't warn you" value.
Exceed this (say, by trying to drive 12 LEDs at 20 mA each)
and expect smoke (or at least don't expect Microchip to buy
into your "defective chip" claim).

Look at section 18.2 "Power Down and Supply Current".
P 168 indicates that at 4 MHz, 5V, room temp, expect to
draw 1.05 mA MAX.  That assumes no driving loads, no
peripherals, just sitting there going "nop/goto $-1".

It also assumes that you were good to the PIC with unused
I/O lines- no floating inputs or non-analog inputs with analog
voltages, no outputs with pullups which are being pulled low
in software, etc.

P 173 indicates about 2 uA for the ADC, and 6 uA for Timer1
(with a 32 kHz oscillator).  I'll leave it to you to figure out
the effect of other peripherals.

Of course, you COULD just measure the current with a 
meter, then make an allowance for overage...
