Keyboard not working when plugging to AC adapter

au flag

I recently installed Ubuntu in my laptop. It was ran perfectly with my wireless keyboard and mouse.

Yesterday, I replaced my wireless keyboard because some keys stopped working and bought a Dell wired keyboard. I connected and tried it with my laptop. It was working fine, but after two minutes, it started stuttering and all keys automatically get typed!

I thought it is keyboard's fault. So I replaced that keyboard with an HP keyboard, but the same problem occurred. However when I unplugged my AC adapter from my laptop, it worked fine. When I re-plugged in the adapter, the problem re-appeared.

How can I fix this so my keyboard works when plugged into power?

You can enter to your laptop's "BIOS" setup, go to a place where you can type something and see if this problem occurs there too. If so, it is a hardware problem...

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.
