Amy tells him to buy a new computer since his video and audio signals are cutting out. He can't read the sign she held up and can't hear her so she calls him to tell him again to get a new computer.

Leonard and Howard are in the lab. It had been over a year since they built something scientific together, but only last week since they built a Lego Millennium Falcon together. Bernie and Penny show up and bring them lunch join them. Their progress is sloe so Penny asks if they could help even though it was a rhetorical question. The girls could wrap some of their pipes with Teflon tape. Penny wonders if it would be funny if after all his years of work if the girls came up with a scientific breakthrough. Leonard didn't find that funny.

Sheldon gasps as the video on his computer goes completely dead. Amy rushes in having missed the computer's passing. Sheldon starts to play "Taps" and then covers his laptop. Amy insists that he is being silly, however, Sheldon reminds her of the lab monkey she got emotional over when he passed away. That monkey had told Amy that he loved her in sign language. Amy gives him a new computer which should make him feel better. Sheldon is upset that she deprived him of all of the fun of picking out his own since it's a very personal choice. He goes through several requirements for his system which Amy and the "guy" at the computer store have already anticipated.

Leonard showed the girls how to wrap their pipes and then they realize that they ran out of solder. Howard and Leonard leave to get it at the hardware store. The girls stay to handle all of the sciencey stuff. After they leave, Penny asks Bernadette what solder is.

Next Sheldon asks Amy if she was going to rob him of the fun of setting his new laptop up. He gets excited when it sets up so fast. With the new 4K resolution, Sheldon tells Amy he'll be able to count to nose hairs in her nose. Amy suggests that he just stare into her eyes. Amy wants to take the old one back to the store so they can recycle it Sheldon doesn't want to do that or get store credit. Amy wonders why he is being weird about it. Instead of explaining it to her, Sheldon wants to show her. Amy has to drive them and sign a nondisclosure document like she did before they slept together.
