1. Remove the bottom plate
This laptop’s bottom panel is held in place by 9 Phillips-head screws. After you undo them, you have to pry the bottom panel with a plastic tool.
2. Battery
Inside, you will find a 53Wh battery. It lasted us for 10 hours of Web browsing, or 7 hours of video playback. If you want to take the battery out, you will need to undo four Phillips-head screws. Then, unplug the connector from the motherboard, and remove the unit from the motherboard.
3. Memory and storage
It’s good to see there are two SODIMM slots for memory expansion. Additionally, there is one M.2 PCIe x4 slot for storage.
4. Cooling system
As for the cooling, there are two heat pipes connected to a rather long heat sink. Then, two fans blow the heat away from the device.

Additionally, it is compliant with the MIL-STD-810H durability tests.When it comes to performance, you are covered by a Tiger Lake-U chip. Provided you are happy to invest more money, you can pair it with the Core i7-1165G7.[...]
