 Hi, this is Nick from Laptop Media, and today we will show you how to open the Delvostro 153535. In order to remove the bottom panel you have to unscrew 8 Phillips head screws. The ones in the top 2 corners are captive, and after undoing them, they will slightly raise the panel up so you can start popping the plate with a plastic tool.

The battery of this notebook is an optional 54 watt hour unit. If you want to take out the battery, the first thing to do is to disconnect the battery connector from the motherboard. The next step is to undo the 4 Phillips head screws that are keeping the battery in place. The capacity of the unit is enough for 11 hours and 7 minutes of web browsing or 9 hours and 5 minutes of video playback. Memory wise there are 2 Sodium slots for up to 16GB of DDR4, 3200MHz RAM. The devices with AMD Athlon Gold 7 220U, AMD Ryzen 3 7 320U and AMD Ryzen 5 7520U come with 8GB of LPDDR5, 5 to 500MHz memory. In terms of storage, there is a single M.2 slot, compatible with 2230 or 2280 Gen4 SSDs. Alas, the slot is limited to Gen3 speeds. Our laptop is configured with a shorter NVMe variant. The SSD is covered by a metal shroud that has a thin thermal pad on the inside. The cooling solution is very basic. It has a single fan and just one heat pipe. We can also spot one heat sink and one heat spreader.
