i also don`t think that you can find something which is noticeably warm this way - 4% of your battery in 12hrs - that "hot spot" should be hard to identify - and opening notebooks for getting access to the all parts of the mainboard may be hard/dangerous.

if your notebook powers down and doesn`t show that something is still "on" and consuming power - i`d call that "broken by design".
it should not be up to the operating system to make sure that all parts of the hardware are switched to off.

if i power down some device and there is nothing showing "hey, here is something active" (e.g. by some led or lcd) - i expect it to stop consuming power. 

maybe it`s not that broken as my PC, which is consuming 20W after power-off  (due to power-supply) - but i really would go ask the vendor and first complain there.

they should know the details.

After poweroff, something still working and consuming power. So I loss 
~4% of my battery charge in each 12h.

If I shutdown my laptop using Kernel 2.6.24/25 when battery is 100%, 
after 12h my battery charge go to 96% (this information is checked with 
kpowersave and with LED available in my laptop that change color from 
blue to yellow when battery is not FULL).

If I shutdown this same laptop by WinXP (I have a dual boot), nothing 
change. So, my battery still have 100% after 12h (or more).

I see a similar problem in EeePC (the problem is with snd_hda_intel 
driver), but I don't have this driver loaded:
