 Hello, this is Laptop Media, and today, we will show you how to open the 2022 version of Lenovo 315 and what's inside of it. To access this notebook's internals, you need to undo 10 Philips head screws. Then, carefully work your way around the bottom panel with a plastic tool, preferably starting from the front. 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 find a 38 watt-hours battery pack. It lasted us for 7 hours and 30 minutes of web browsing, or 7 hours of video playback. You can take it out by removing the 4 Philips head screws that hold it in place. Also, don't forget to unplug the battery connector. Here, you get either 4 or 8GB of DDR4 memory soldered to the motherboard. In addition, you can use the single Sodom slot to expand your RAM. Models that have the smaller battery pack feature an M.2 PCIe X4 slot as well as a 2.5-inch SATA drive bay. Lenovo provides you with mounting and connecting accessories inside the box, which is great. Units equipped with the larger battery omit the SATA bay. Cooling wise, there is one heat pipe, a heat sink, and a fan. It's good to see that the VRMs are also being cooled.
