I have two T420s, both with Crucial 1TB SSDs. Both work. They were bought
from https://www.tier1online.com/ . They provided the laptops OK but their
after sales support ("can I buy a replacement battery", "where can I buy a
replacement keyboard?") was hopeless.

One T420 has Ubuntu x86_64 21.10 beta and works fine.

The other T420 is my main system and it has Ubuntu x86_64 20.04.3 LTS and
works fine. I am using it to write this email.

However, I am not booting Windows. I only have Ubuntu Linux installed.

They are a bit old but still useful. They did come with Windows 7 installed
on HDD and I changed the BIOS to legacy boot, wiped the HDD and installed
Ubuntu Linux on them.

Years later, I replaced the HDD with a Crucial 1TB SSD and used it a bit as
a test bed. It worked. Later on, when I was happy with that, I replaced the
HDD in the other T420 with a Crucial 1TB SSD.

At least once a month I backup key personal files on my main system.

HTH,


Ian
