In defense of this machine, I purchased one used for team training purposes it cost me 500 dls,
Intended use is to serious VMs emulation (Clusters with 8 nodes using 6 GB RAM each vm), and was a total bang for the buck since very few laptops (Business, Gamer trim or workstations), can support 128 GB ram, And something I noticed is when you have a discrete GPU with actual VRAM, OS video memory usage is minimum, this is recommended for VMs.
It came with quadro T1000 which is very power efficient with low heat, I don't see an objection if this machine is purchased as a cheap gaming machine but could be an overkill.
Adding more disks were easy since in China, Lenovo compatible SATA adaptors are incredible cheap, so added an extra 1 TB NVME disk and a 1 TB SATA disk, and in total 96GB RAM (16+16+32+32), used already installed 16GB ram and purchased 2-32 GB timetec and 1 - 16GB Kingston 2666 non ddr. We didn't replace the intel 660P 512G NVME because it will only host the OS (windows 11 with VmWare workstation player fully licensed) to avoid tricky network configurations since we need to focus on the automation and control of the cluster's nodes. And we are departing from ESXI for training machines due to cost concerns.
To perform upgrades you need to be extra careful; because to upgrade upper side ram you need to remove keyboard and by mistake broke 1 key, but like I said in China replacement was easy and cheap to find, so I replace keyboard without no issues. I got the lighted US version but since this machine is meant to be accesses always in RDP, we repair it anyway for consistency since brand new machine P series will cost us 10 times what we paid for it.
There are OLED and IPS 4K display options for this machine, What we got was a Full HD IPS I attested the same result than this review, good colors and brightness but noticeable light bleeding, And in this model basically you need to destroy your old display in order to upgrade it to a new one, since it is not bracket based, it uses a double adhesive tape which hardens with age; so you basically need to tear it apart with an exacto knife and maybe use a heater and result depends on your luck because is easy to damage the display and maybe the chassis. So for our intended use is was a big NO-NO, but I saw in China 120 dlls 4K displays and 250 dlls OLED respectively,
please remember a similar laptop with a 128GB ram, 3 TB disks, 4K Oled was +5000 dlls only 3-4 years back, so from a cost perspective is worth to be considered. We could not find a better deal.
