 Hello, this is Nick from Laptop Media and today we will show you how to open the Asus Vivo Book 15 F-1504 X-1504. For removing the bottom plate you need to unscrew 10 Philips head screws. Then, you can pry the bottom panel with a plastic tool. One of the top two corners is the best starting point. 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. You can have a look at the inside of the bottom plate. The battery here is a 42 watt hour model. If you want to take it out, pull out the connector from the main board and you also have to undo the four Philips head screws that are fixing the unit to the base. The capacity is enough for 8 hours and 20 minutes of web browsing or 6 hours and 40 minutes of video playback. You can find this laptop with 4 or 8GB of soldered DDR4 memory but there is a Sodium slot for future upgrades. So, the maximum possible amount of RAM is 16GB of DDR4 memory. Note that the stick is rated at 3200 MHz but it works at 2666 MHz frequency. For storage, you get one M.2 slot compatible with Gen4 SSDs. Cooling is basic. It has a single fan, one long heat pipe, one heat sink and a heat spreader.
