 Hello, this is Laptop Media, and today, we will show you how to open the Dell Latitude 155 511 and what's inside of it. This notebook has a total of 8 Philips head screws that hold the bottom panel. After you undo them, you just need to pop the plastic clips with a plastic pry tool, and you should be able to effortlessly lift the panel away.

Thankfully, we see two significantly thicker heat pipes, when compared to the Latitude 155 510. Also, the fan seems to be a bit larger as well. Moreover, this machine can employ up to 64GB of DDR4 memory in dual channel, and it's all user replaceable. And in terms of storage, there is a single M.2 PCI-EX4 slot, as well as a 2.5 inch SATA drive bay. Not on the last place, depending on the configuration, you'll get one of three different batteries. A 51W 1, a 68W 1, or a monstrous 97W unit. If you'd like to see more disassembly videos of the latest notebooks we would highly appreciate if you hit the like button and subscribe to the channel.
