Apparently this was auctioned off from one of the three! From the Bond Life website:
"One of three laptops used in filming, preloaded with film graphics, will be auctioned at Christie's on February 2016. The laptop on auction is in working order with an extra battery pack, laptop AC adapter, battery charger, power supply with power cord and soft case. Estimate: 4,000–6,000 / $5,700–8,500 / €5,200–7,800"
