A relic is "a surviving memorial of something past", which seems just about perfect for your purpose.
To be sure, the most common association is with the relics of saints - fragments of the True Cross, or the bones of St. Mark - but relics are not necessarily religious. (Despite the similarity of spelling, "relic" and "religion" are derived from different Latin roots.)

Historical artifacts, outmoded ideas, and even retired persons are often called "relics", so there's no reason your old laptop can't be one too.

A few examples of this usage of "relic":

A Burial, Ella Wheeler Wilcox:

To-day I had a burial of my dead.
There was no shroud, no coffin, and no pall,
No prayers were uttered and no tears were shed -
I only turned a picture to the wall.
A picture that had hung within my room
For years and years; a relic of my youth.
It kept the rose of love in constant bloom
To see those eyes of earnestness and truth.

The Third Etage, author unknown, from "Household Words: A Weekly Journal, Volume 1" (edited by Charles Dickens):

It so happened that, as I dived into one of my big trunks in sorting my clothes, I came upon a leather case that contained a daguerrotype, a relic of my youth.

Matters of the Heart, Danielle Steel:

"I was thinking it might be nice to go to the Cape. I'd like you to see the house. It's very simple, but it's a relic of my childhood. That house means a lot to me."
