I don't know, my newest motherboard is 3-4 years old, and while it is thankfully not new enough to have UEFI, it does have these pins. Clearly mentioned in the manual, too. > IMO no board without that should ever be considered for purchase. > YMMV of course... Amen. But the OP's machine is a laptop, and the owner had difficulty with removing the battery without the user manual. Disregarding whether or not he should even attempt this at all, it would involve opening his still-under-warranty machine to such a degree that it would now become a no-longer-under-warranty machine :) So whether or not the pins are there is not really that important in this setting, I would think.

I am also a little wary of his statement that it took them two _weeks_ to examine a machine he delivered to them for service. Where I live, a small place in Norway, the people I use will normally do things within a few hours. And it's not like they have lots of competition, either. Maybe I'm just spoiled & lucky, though.
