 Hello, this is Nick from Laptop Media, and today we will show you how to open the Asus ZenBook Duo UX8406. If you want to open this device, you need to undo 12 Torx head screws. One of them is hidden below the kickstand that is fixed to the base with two pairs of screws. To pop the small service door, you have to undo two more Torx head screws. You have to detach the battery and the second display connector. The latter is a ribbon connector and you have to flip up its plastic cap before pulling it out. After that, turn over the machine to pry the zone around the second panel with a thin plastic tool. You can start from the back or the sides, the front should be last. When that is done just raise the display and lift it away from the chassis. Please remember, it would be of great help to us if you just hit the like button and subscribe to our channel. That would motivate us to make even more and better videos for you. Here's how the second panel looks on the inside. The first thing to do here is to detach the two connectors in front of the hinges. Remove the two antenna cables of the Wi-Fi card. Detach the two fan connectors as well as the ones for the speakers. Undo all the screws on the motherboard that are marked with a white arrow plus the two below the heat sinks. Oops, wait, we forgot something. The memory is soldered, but you get up to 32GB of LPDDR5X, 5600MHz RAM which should be enough for most people. For storage, there is one M.2 slot for 2280 Gen4 SSDs. The thermal system has two fans, a pair of heat pipes, two side mounted heat sinks and two heat spreaders. If you want, you can also remove the fans. Each one is held to the base by three Phillips head screws. This laptop has a 75Wh battery. To take it out, undo the three Phillips head screws that keep the unit in place. The capacity is enough for 16 hours and 40 minutes of web browsing or 10 hours of video playback. The result is very good. To achieve that, you have to apply the balanced preset in the Windows Power and Battery menu. Select the standard fan mode, turn off noise canceling completely and use the Dynamic Refresh Rate option in the My ASUS app.
