Does this picture prove that ancient Greeks used laptops?

There have been several discoveries proving that humans in the ancient civilisation lived a far more advanced lifestyle than their modern descendants. In fact, the ancient scriptures talk openly about fast-speed aeroplanes, atomic weapons and unfathomable powers.
But, going by an ancient Greek stone sculpture, any naive mind would think that the Greeks were probably the first inventors of laptops! A Greek art sculpture, put on display at the Getty Museum in California, depicts a “Grave Naiskos of an Enthroned Woman with an Attendant” dating back to 100 B.C. It has a queenly woman, gracefully seated on a chair with her right hand at the lid of a shallow box held by a (servant) girl.

However, a few social media users have assumed the shallow box to be a laptop, considering its design and the two holes drilled at the side of the box that resemble USB power ports. Some also opine that this could be a jewellery box as well.
On the other hand, some critics have explained that the device is surely a tablet but a wax tablet used for writing on with pen or stylus. Others state that it could not have been a laptop because there was no electricity or power charger during those times. There are other users who believe that the woman in the sculpture is holding an abacus, which was a mode of measuring in ancient Greece.

One of the most logical explanations that have come up is that the sculpture was damaged over time, and hence the two holes were drilled into the slab to repair them with metal rods.

Going by the above assumptions, anything can be true. Share your thoughts if you too have an opinion on the same.
