It's not accepting the key in any of the installs.

Seems like this shipped with Win 8 & not 8.1, could you remember what version SL or Pro, if it shipped with 8 & you are not certain what the product key is, rw everything & Aida64 would read the key correctly. Installing 8 first would detect the key correctly from the bios & be able to activate, you would then have to upgrade to 8.1 via store. it is possible to do the upgrade with media but that entails first reading the correct key after 8 install, doing a upgrade with a dummy key & then removing the dummy key via the command I posted earlier & then activating with your correct key.
It sounds complicated but is very easy. The issue usually is that laptops shipped with the first version of 8 would not read the key correctly from the bios when doing a install on 8.1 media unless doing a clean install. What makes it worse is Microsoft just putting an 8 sticker on the laptop without specifying what version or distro of 8 it is.
