 Hello, this is Laptop Media, and today, we will show you how to open the Dell Vostro 15 3510 and what's inside of it. To take this laptop apart, you need to undo 9 Philips head screws. The 2 in the back edges are captive and lift the bottom panel so you can start the prying process from there. 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 battery, you get 2 options. One with 41 Watt hours capacity, and one with 54 Watt hours. We got the smaller unit, and it lasted us for 7 hours of web browsing, or 6 hours and 30 minutes of video playback. To take it out, you need to unplug the battery connector and undo all 3 Philips head screws that hold it in place. As you can see, there are 2 Sodom slots for memory upgrades. Storage wise, you get 1 M.2 PCI EX4 slot, as well as a 2.5 inch SATA drive bay. However, if your laptop is equipped with the larger battery pack, the HDD bay will be blocked. As for the cooling, you get 1 heat pipe, shared between the CPU and the GPU, which ends up in a rather small heatsink. The graphics memory and the VRMs are not being cooled.
