 Hello, this is Laptop Media, and today, we will show you how to open the Dell Latitude 155 510 and what's inside of it. To secure the bottom panel of this notebook, Dell is using 8 Philips head screws. After you undo them, they will stay attached to the plate. Then, you just need to pry the panel away with a plastic tool. 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. In terms of cooling, we see two relatively thin heat pipes, as well as an average size fan. Thankfully, as a typical business outfit, the Latitude 155 510 supports up to 32GB of DDR4 memory, via its two Sodom slots. Additionally, you can install a 2.5-inch SATA drive, but interestingly, Dell has limited your choice to only one of the two, as the M.2 drive stands in the way of the SATA drive bay. Battery-wise, there is a beefy 68Wh unit. However, Dell sells the notebook also with a 42Wh and a 51Wh variance.
