Just bought a Flex-14API, wondering what is replaceable/upgradeable.

I just bought a Flex-14AP (with a Ryzen 5 3500U, a 256GB SSD, and 4GB onboard RAM plus 4GB in the bay), and I’m wondering what on it is replaceable/upgradeable, if it comes to that. I know that the battery is replaceable and the RAM is upgradeable, but is there anything else that falls under either of those two categories, like maybe the storage?


The storage looks like an M.2 from the pictures I can see online, but is it something that can be upgraded without compromising the machine’s integrity (like Apple’s T2-linked drives in the MacPro5,1)? If it is upgradeable, what keying is it (If I want a replacement drive)?


I’m wanting to put 20GB (or 36GB if it can take a 32GB SO-DIMM) of RAM and a 1TB or 2TB drive in this laptop, because I’m a big spender I guess. I know that’s overkill, but I think I have the cash to spare, and I want to just never have to worry about it.

You can upgrade or replace the following parts:

  • The M2 SSD (1 TB+ should be supported - watch out for BIOS updates)
  • The battery
  • The non-soldered RAM (up to 16 GB) which adds up to 20 GB total
  • The WiFi card

As you can see at least your data will be accessible if your motherboard becomes faulty.

Adding a 8 GB stick of RAM and maybe a larger SSD may be a good upgrade depending on the model.

Perfect! Thanks! Mine was sold as having a 4GB stick, but actually came with an 8GB stick, so I've just been running it as is for now. I wish I could go all the way to 36GB, but even 20GB is honestly more than enough for a laptop of this caliber anyways.
