Have you tried to start another Multiplayer match on the Laptop (it doesn't need to be played, just maybe start a private match an leave). This way, the achievements are updated with the online N7HQ (just make sure you have all the free Multiplayer DLC installed on the laptop as well).
I wasn't game to get the laptop to 'sync' with origin in case I lost the achievements on there also. I've completed the game twice but only once on the laptop, my original run (didn't have the Citadel DLC or Leviathon on it) or my Insanity completion which to be honest is the only achievement I really care about. Although, when I play Multiplayer with all my achieves missing I have been kicked a few times before tha start of a match, based on my lack of achieves.
The reason I was using offline on the laptop was when I logged into Origin it was asking me to update the patch. As mentioned I'm not sure if somehow that patch was responsible or me getting into Multiplayer.
I can give it a go I suppose, losing the achives on there also isn't going to matter that much anyway, now that I have the list of the ones I've lost I suppose.
