Please note: I believe this information is accurate, but please presume there could be errors and don’t hold me responsible for any costs or problems. Also I presume that manufacturers sometimes make changes to hardware. Also I don’t own a stand for the thin client!

Introduction

I purchased the old T5520 2020! The 2006 thin client is old and low spec which means for some people it’s not worth using. However I’m currently having fun, seeing what I can do with the thin client and at the time of writing, I’m currently using FreeDOS on the device.

BIOS Password: If you can’t gain access to the T5520’s BIOS settings due to a password, I’ve written a blog post here about how to remove the password.

The photos

I thought it would be helpful to provide hardware, BIOS & Windows CE photos to help others.

On my case it says t5000, but it’s actually a t5520 inside.

My thoughts on using the T5520 without Windows CE

From my perspective, when replacing Windows CE the biggest problem with this thin client in 2020 is the 128MB of non-removable RAM. Also 64MB flash memory is an issue and rather than looking to see if I can replace the flash memory, I’m currently using a USB memory stick for additional storage.

Final thoughts

There are better thin clients that you can do far more with. I’m not going to walk away from this device yet and at some stage I plan on publishing a blog post about using FreeDOS on the T5520.
