How much total RAM does my T480s have?

I just purchased a new T480s from ebay. I have not received it yet. I want to confirm the total RAM before the seller ships it to me. It is new-in-box and cannot be opened and turned on. But I do have the model number.

The ebay listing advertised 16 GB of RAM. However, on [lenovo.com](https://lenovo.com), using the serial number, I see these specs which mention 8 GB of memory:

Processor: 1x Intel Core i7-8550U Processor(Core i7-8550U)
Memory: 1x 8GB DDR42400
Operating System: Windows 10 Pro 64(EN:English)
Hard Drive: 1x 512GB PCIe NVMe OPAL
Wireless Network: 1x Intel Wireless-AC 8265 2x2 AC
Ports: 1x Headphone & Microphone combo Jack
Camera: 1x
Graphics: 1x Intel UHD 620
Monitor: 14.0 FHD LED


The serial number specific FRU BOM (as-built) lists memory as:  

8GB DDR4 2400 SoDIMM MEMORY    01AG711    SM30G16509    qtu 1    CRU Mandatory


From psref, the T480s has these generael memory specs:

max RAM of 20GB or 24GB max / 2400MHz DDR4, dual-channel capable, with 4GB or 8GB memory soldered to systemboard, and one DDR4 SO-DIMM socket.

It is a Machine Type Model: 20L8-S2UT00. Unfortunately, psref.lenovo.com doesn't have a listing for that model. If it did, that would clear things up.

From what I have seen, I can't tell if there is 8 GB soldered to the systemboard and 8GB in a slot, or if there is some other configuration.

How would I confirm the total installed RAM before I receive the unit? It is new-in-box and I cannot ask seller to unbox it and start it up because then it will no longer be new-in-box. Seller plans to ship it to me tomorrow and I do trust the seller, so I am assuming it is 16 GB. But if it isn't, I would prefer to tell the seller to cancel the sale before shipping to save both the trouble of a return.

Memory
20GB or 24GB max / 2400MHz DDR4, dual-channel capable, 4GB or 8GB memory soldered to systemboard,

one DDR4 SO-DIMM socket * System clocks down for processors with lower memory controller

I would check your soldered memory for starters,

Unless your machine has 0 soldered,  do not expect 24GB. (8 soldered+16 stick),

Your best bet is 4 soldered and  8GB stick, 12 GB max. or 4+4=8 not max.
