 Hello, this is Laptop Media, and today, we will show you how to open the Dell Latitude 159520 and what's inside of it. 9 captive Philips head screws are separating you from this laptop's internals. After you undo them, pry the bottom panel with a plastic tool, 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. Inside, we see a 48.5 watt-hours battery pack. Dell also sells the laptop with a larger 88 watt-hours unit. With that said, our model lasted us for 14 hours and 30 minutes of web browsing, or 10 hours of video playback. To remove it from the device, you first have to unplug the battery connector. Then, you need to undo 5 Philips head screws. Then, carefully separate the cables from it, and take it away from the laptop. Sadly, the memory here is soldered to the motherboard. However, you can pair the laptop with 8, 16, or 32 GB of LPDDR4X RAM. As for the storage, there is one M2 PCI-EX4 slot, which only fits 30mm drives. Cooling wise, there are two heat pipes, connected to a heat sink, and a medium-sized fan.
