Inside Fujitsu Lifebook U939X – disassembly and upgrade options
So, how easy it is to take apart Fujitsu’s tiny business competitor. It looks quite rigid with the amount of visible and rather large screws on the bottom plate. Let’s get inside!
1. Remove the bottom plate
For a laptop that sits comfortably on the scale that displays 1.00 kilos, we find the method of securing the bottom plate a little weird. Fujitsu has used a total of 16 Phillips-head screws… In contrast to the Lenovo Ideapad S940 that has only four of them. On the bright side, when you manage to remove them, the bottom panel falls just like that – easy-peasy.
Fujitsu Lifebook U939X has been equipped with a sizeable 50Wh battery pack which should provide a decent amount of time away from the plug. One of the most important things you have to remember is to always unplug the battery connector when you are touching the motherboard.
3. Memory and storage and cooling
The first thing we’ve noticed (and we’re sure you did too) was that there are no visible RAM DIMM slots. Well, this is because, the memory in this device is soldered to the motherboard, so choose wisely how much RAM you need before you buy.
Then, there is the cooling solution, which incorporates an incredibly thin and short heat pipe that connects to an even smaller heatsink. Additionally, the fan that the Lifebook U939X is equipped with is yet again, not boasting a huge size. At least on the bright side, the path between the die and the actively cooled area is very short, so it should be pretty quick to stabilize its temps back when its load is decreased. By the way, just below the CPU, you can see the M.2 NVMe slot – there are some upgradability options, thankfully.
