 Hello, this is Laptop Media and today we will show you how to open the Dell Vostro 143401. 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. For popping up the bottom panel, you have to undo just 7 Philips head screws. However, there are 2 captive screws on the back corners for even easier bottom plate prying. Unfortunately, the battery comes with a modest capacity of just 42 Watt hours. When it comes to upgradeability, this laptop definitely has something to offer. It comes with 2 RAM so dims, a single M.2 PCI EX4 slot, and a SATA slot for regular SSDs or a big hard drive for backup. The cooling is the bare minimum for that kind of device, a single fan, one heat pipe, and a tiny heat spreader.
