Hi everyone 
I'm "resurrecting" this long-running topic, to share the specs and history of a "Dell Latitude E6440" (sometimes referred to as "Dell Latitude 6440") laptop computer that I have.
I live in Portugal (a country in Europe and in the EU / "European Union") and I bought this computer used, from a seller in "eBay UK", in the year 2019 (this was "pre-Brexit": back then the United Kingdom was still also in the European Union, so I didn't have to pay Customs Fees to buy it). This particular machine, back then in 2019, was 5 years old (it had been manufactured in 2014).
This machine came with a dual core 4th Generation Intel Core i7 Processor (CPU) ; 16 GB of RAM ; a 256 GB SSD and Windows 10 Pro (pre-installed from the eBay seller).
The computer is serving as a Media Player, connected with an HDMI Cable to a LED TV
This year (2025), a few months ago, considering that Windows 10 is going to stop receiving free security updates in October, I decided to delete Windows 10 and install "Ubuntu MATE 24.04 LTS" ("Noble Numbat").
The SSD came to me configured as a MBR (Master Boot Record) Device and not as a GPT (GUID Partition Table) one. I didn't want to risk changing it from MBR to GPT and I also didn't want to mess with the two pre-configured "system" partitions that it had. So, during the Ubuntu MATE 24.04 installation (that I did from a USB flash drive with the Ubuntu MATE live environment and installer ) - and given the limitations of the "Ubuntu 24.04" installer regarding MBR configurations - I ended up having to switch back-and-forth from the installer to the "GParted" program that is available in the "Ubuntu MATE 24.04" live environment in the flash drive. I deleted the Windows partition, recreated it as an extended partition and created a logical partition to install "Ubuntu MATE 24.04". It involved a bit of work, but it worked!
So - and without further ado - here are the System Specs of this "Dell Latitude E6440":

Had an old version of Mint with auto login.. silly boy. Wiped it with a fresh install of U-Mate and as always, she runs just fine on these older machines
