The RAM doesnt matter, it has 8GB builtin (or is there a 4GB model??) and one slot flexible.
Yes the CPU is okay for regular office stuff. But the AMD linux support was suboptimal, I had regular suspend-resume issues where the lockscreen would freeze and I needed to hard shutdown.
And... for some reason that thing doesnt even boot anymore. Removed the battery, using official charger. Doesnt boot into the BIOS anymore, no idea what I could do honestly.
They gave some coreboot devs laptops but didnt invest anything apart from that, afaik. The result was not working well enough, so they use insyde (which has pretty cool features but also past security vulnerabilities and it is backdoored by Intel & the NSA)
Like, UEFI being backdoored by the NSA is not a conspiracy. "Persistence" in "end user device data retrieval" was one big goal. Persistence means than an OS reinstall, Secureboot, boot integrity, QubesOS disposable Cubes etc. will all not protect you, as that shit is in the firmware!
No security or privacy without coreboot. Google knows that and has all their servers on coreboot and also all Chromebooks. Android is ARM so that is different but also WORLDS more secure than any secureboot garbage.
I HIGHLY recommend against the T495. That thing has a great keyboard, fingerprint sensor, okay camera and mics, okay ports. But it is underpowered af, and Thinkpads always have the Thinkpad price.
It has a great chassis, but my coreboot Clevo NV41 has double the performance and kinda same battery life.
Their firmware updates are pretty late and they ditched coreboot.
But I guess the hardware is awesome. Keep in mind that these thunderbolt adapters suck quite some battery, so having a laptop simply with the ports you need uses up less battery. Also, the modularity may not be needed and causes it to be less stiff.
Also very important to have backups.
I needed my backups 3 times or so, where literally all data would have been gone without them.
