1. Remove the bottom plate

There are only 7 Phillips-head screws that are separating you from this notebook’s internals. Two of them, located on the back corners, are captive, and after you undo them the bottom panel will slightly lift. This is where you want to start the prying process.

2. Battery

Once you’re inside, you will find the 40Wh battery pack, which powers the laptop when it’s away from the plug. This device can also be found with a 53Wh unit.

3. Memory and storage

Thankfully, there are two RAM SODIMM slots, that can fit up to 32GB of DDR4 memory in dual-channel mode. As for the storage, there is one M.2 PCIe x4 slot. Also, there seems to be a second one, but the situation there is very weird. In our unit (which has the smaller battery), we won’t be able to use this slot, because the shape of the speaker prevents us from installing a drive in it. However, according to Dell, if you order the laptop with Intel Optane storage, you will be able to use it. Sounds quirky, doesn’t it?

4. Cooling system

Here, the cooling solution comprises a single heat pipe and a rather small heat spreader.

Well, it comes equipped with Intel's Tiger Lake processors and can [...]


  • Wi-Fi 6 connection, MicroSD card slot, and a well-populated I/O
  • Two RAM SODIMM slots, and PCIe x4 support for storage
  • Thin and light body

  • A ton of confusion around its second M.2 slot

  • The model with a 40Wh battery doesn't shine with great screen-on times
