PCIe NVMe SSD upgrade for Y8A57EA#AKC (ProBook 250 G4)

[pagyo]

Hi, is it possible to upgrade the notebook above to M.2 SSD NVMe?

I found the socket under the cover of my notebook and I bought one SSD module, but when I installed it the computer won't start. After removing the M.2 SSD computer works again. I even don't know what PCIe version the notebook has, please help!

SSD what I bought is a 4th generation module, but theoretically PCIe devices and ports are backwards compatible, so it couldn't be a problem.

SSD modul I installed is: Silicon Power UD85 250GB

Sorry I messed up the title, the proper model is: ProBook 450 G4.

Even though the built-in socket only uses an M key (referring to M.2 NVMe) and not B+M, it looks like M.2 SATA to me. The connector is misleading, unfortunately there is no label on what it is for.

@pagyo,

Unfortunately, you are right. User manual for your model (page 3) indicates only M.2 SATA SSD is supported.
