Lenovo ThinkPad X1 Carbon Gen 11 review – it’s ultra-light and the battery life is outstanding


Disassembly, Upgrade options, and Maintenance

If you want to open the device, you need to undo 5 captive Phillips-head screws. Then you can pry the bottom plate starting from one of the top two corners and then you can work your way around the zone behind the hinge.

Here’s how the bottom panel looks on the inside.

The battery is a 57Wh unit. Because the connector is built into the unit you need to wear gloves in order to prevent short circuits. Then, you have to undo the 6 Phillips-head screws that are fixing the model in place. The capacity is enough for 25 hours of Web browsing or 20 hours of video playback. The result is just outstanding!

Here, we have a soldered memory. On the bright side, you get up to 64GB of LPDDR5x-6000MHz RAM which sounds future-proof. The 32GB configurations come with the same memory clock while the 16GB iterations rely on 6400MHz memory frequency. Note that the RAM is rated at 7500MHz for all machines but it operates at a lower frequency due to platform limitations. There is just one M.2 slot for 2280 Gen 4 SSDs. It’s protected by a metal plate that has a cooling pad on the inside. Another pad is placed below the NVMe.  Next to the cooling, you’ll find the WWAN slot for optional 4G or 5G connectivity. Another pad is applied in front of the slot.

The cooling seems basic but it seems enough for a U-series CPU. It comprises two small fans, one thick heat pipe, a heat sink, and one heat spreader.
