First some background:
I picked up one Dell Optiplex 5050 and two 3020 MFF desktops, without power adapters. They were super cheap and figured why not? I looked at Dell's website, which is selling the power adapters for $45 and said no effin way. So I bought a compatible adapter off eBay for $15. Right voltage, amperage, barrel connector, thought I would be good to go. It arrived, I plugged it in, and everything worked... sort of. It seemed much slower than it should have been. I tried the other 2, same thing. Everything was working, but felt slow. I installed Windows 11 and it was slow as well. However, that when I realized it was running at 800Mhz, rather than the 2.9Ghz. After doing some research, I found out that if you arent using a real Dell compatible power adapter it will put the computer in low performance mode for "safety." This cannot be disabled in BIOS, as far as I can tell. However, I did find software on Windows called ThrottleStop that allowed the machine to run at full speed.
How can I do this in Ubuntu, as I am not paying $45 to Dell for a 65W power adapter?
