Dell Optiplex 5050 and 3020 MFF Power Adapter

us flag

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?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
