The laptop is a Thinkpad Helix, it has very minimal stickers on it.
Its comes with a Win 8 Pro sticker, thats it, no Windows product code. There is a Lenovo product code, which I was able to check the warranty information, which works fine but no way for me to restore to original OS either.
I think it did come with an original OEM Win 8 Pro, but someone reinstalled the laptop before selling it to me
I tried to reach lenovo on several forum trying to find a way to reset this to original factory, but seems no answer from anyone.
