I have no special information. It sounds like you're missing a digit or two
on the SNID. I don't know about the serial.

serial numbers are 22 alpha-numeric characters, and will always use zero
and never the letter O

If dmidecode (mentioned by Jeffrey Walton in this thread) doesn't work, you
might try the ACER serial detection tool mentioned on the page linked
above. Alternatively if the laptop still has some flavor of Windows
installed on it, you might use the Care Center or Identity Card apps (as
described on the page linked above).

Finally, if you cannot discern a valid number, it seems possible the number
has been altered or the laptop is counterfeit. But again, I have no special
information... just a few old laptops I can look at whose numbers were
valid.
