LG Gram 16" and 17" Part numbers

[Samir]

So I've just made my first big notebook purchase in a few years, getting some 'new to me' LG Grams, the 17z90q and 17z90n.  But what do these part numbers mean anyways?

 

Well, here is what I what I was able to deduce with all my research.

 

The first two digits are the screen size, 16 for the 16" and 17 for the 17".  This may even apply to their other Gram model sizes, but I haven't looked into it.

 

The next letter seems to always be a 'Z' on the 17" and "T" on the 16".

 

The next two digits are kind of interesting, typically '90' for the 17", except there have been 'half-year' models where there was a '95' model where some things were updated from the '90' of that year, but it was not the full next year model.  For all effective purposes, it's a different model than the years it is stuck between.  These '95' models seemed to happen in 2020 and 2021.  So there were what I would call a '2020.5' and '2021.5' model.  Also, the original 17" Gram used '99' vs '90' or '95'.

 

The last digit is the model year:

r = 2023

q = 2022

p = 2021

o = never used since would probably be confused with zero used on the first 17"

n = 2020

0 = 2019

 

This is just what I've been able to figure out so if there's additional info, feel free to add to it!

Good summary. I have the 17Z95P-K.AAE8U1, so that's 17", 'mid year', 2021. 

 

The '95' part is probably the least 'satisfying' in your analysis, as it may also be used to indicate deviations from the base spec? Or, could it reflect finger print reader? Mine does have an FP apparently (don't use it). And it has backlit keyboard. 

 

The 'K.AAE8U1' part of my model number is presumably there to cover CPU (i5, i7, etc), memory size (16G, 32G, etc), storage size (512G, 1T, etc), windows version (Home, Pro).

I can't believe I didn't see your reply until revisiting this thread to remember what I knew about the part numbers!

 

The 95 is the least satisfying for sure because in my research I believe I even found variations between 95 models, with some having things like the fingerprint and backlit keyboard and others not (or some other features--can't recall exactly atm).

 

Yep, the rest of the part number went into cpu, memory, storage and OS.  I didn't try to decipher that as I think there was a decoder for that available.  Can't remember anymore. 😞  I think it might have even been on LG's support site or sales site.

Somewhere in that string of characters will be something to designate the country/region parts as well as the other hardware differences. eg the computers sold in UK will have a UK keyboard.

 

This Amazon UK listing covers four different specs, all starting 16Z90R-K https://www.amazon.co.uk/LG-ultra-lightweight-i7-1360P-Windows-Obsidian/dp/B0C1HCCVS7/

16GB RAM + 1TB SSD = AA78A1

16GB RAM + 2TB SSD = AD7AA1

32GB RAM + 1TB SSD = AD78A1

32GB RAM + 2TB SSD = AA7BA1

The same last 6 characters are also used for the equivalent specs in the 17" version https://www.amazon.co.uk/LG-ultra-lightweight-i7-1360P-Windows-Obsidian/dp/B0C1HCBFYN.
