Lenovo ThinkPad L15 Gen 1 (AMD) - DRAM soldered?

[_roman_]

Hello. May I ask for additional informations please? I checked on my tablet the lenovo homepage and reddit but I'm not 100% sure the information is correct.


I bought a refurbished (sorry its german for the tech specs from the invoice):
Lenovo ThinkPad L15 Gen 1 (AMD)
Displayauflösung: 1920 x 1080 FHD | Grading: Fair | Prozessor: AMD Ryzen 5 Pro 4650U @ 2,1 GHz | Tastaturlayout: Deutsch (QWERTZ) mit Ziffernblock | Betriebssystem: Windows 11 Professional | Datenspeicher: 250 GB SSD | Arbeitsspeicher: 8 GB DDR4 | Displayart: Mattes Display | Webcam: Ja | Fingerprintreader: Ja | Tastaturbeleuchtung: Nein | LTE: Nein

I'm not so much in those mobile processors and lenovo equipment.

• Does this device have two dram slots which are replaceable?

I tried to find gen 1 amd page on lenovo homepage. It's hard to find. I do not want to use reddit as a source for technical specs?
Reddit claims that device may have two replaceable DDR4 SODIMM slots.

Does it matter much to have two identical DRAM modules in a laptop? I'm not sure, but I think the uefi is locked anyway for anything.

• Would you upgrade that DRAM or leave it as is? (depends if the dram is replaceable)

• Which kind of NVME slots?

It seems there are one M2 2242 PCIE 3.0x4 Slot and a M2 2280 PCIE 3.0x4 Slot. I would be happy if there would be any specs.

Are those M2 2242 PCIE NVME common in laptops these days?

• Regarding cpu (sources I checked techpowerup / amd)

Am I right in those findings?

It seems ryzen 4xxxU processors are Zen 2. Some do not have Hypterthreading.
Ryzen 5500U, 5300U seems to be also Zen 2.
Those 4xxxU Pro processors seems to be Zen 2 but with Hypertreading.
I have the feeling AMD Ryzen 5 Pro 4650U is a relabled Ryzen 5500U.

• Which desktop ryzen is equivalent to AMD Ryzen 5 Pro 4650U? (i tried to find some benchmarks and such - but i highly doubt those sources)

• I'm just curious. Would you pay 250€ with one year "warranty" for this refurbished device. It comes with a refurbish Microsoft windows license.

Thanks for your time for reading.

Note: I'm not sure if a notebook question belongs in generic hardware. I tried to find the proper section before posting.
