Saving Old Computers – and the planet

Last Updated on February 3, 2026 by David Both

I have written about how Linux can keep old computers running and out of landfills or recycling streams. My most recent related article is “How Linux rescues slow computers (and the planet),” and it discusses one of my computers that has a BIOS date of 2010 so was about 14 years old. It died when the motherboard failed

I now have an old Dell I am working on that has a BIOS date of 2005 which makes it at least 19 years old. According to the Intel web site the Pentium 4 processor was released in the 1st quarter of 2004 so that BIOS date is probably as good as anything to estimate the age of the computer. That tracks well because a search on the Dell web site for this computer’s service tag number found that the computer was built in August of 2005.

You can see the specs for this system which are pretty minimal.

It has a single 3GHz Pentium 4 processor with Hyperthreading so the equivalent of 2 CPUs. It originally had 2GB of DDR 533 RAM so I added 2 GB for a total of 4GB which is the maximum amount of RAM supported by this system.

Naturally, I installed Linux on it just to see how it would work. This old computer works just fine with the most recent version of Fedora. My next test is to see how well it runs a Linux VM using VirtualBox.

So yeah – when I say that Linux keeps old computers running, it is absolutely the truth.

I borrowed this computer from Digital Bridge in Wake Forest, NC to do some testing. They have a number of these old computers that were regifted to them but Windows is pretty useless on them. The only way to get them to work reasonably well is with Linux. Linux can also keep your old computers working far beyond the point where it is normally assumed they should be discarded.

In addition, Linux keeps these old computers safe from malware and bloatware which is what really causes them to slow down.
