very interesting, thanks for posting! Haven’t really had a chance to crack mine open yet. Assuming the battery is connected via a normal plug (not soldered?). Probably won’t be worth replacing the battery vs buying something new in a couple years when the battery dies, but good to know it’s possible I guess.

Thx for the pictures. Interesting to see the internals.
Strange that only the cpu is in contact, since there are more possible contact points.

I knew that the “raw” notebook is used as a base for different manufacturers and resellers but it is impressive how many different versions are out there.
I just found the Onda Xiaoma 31 wich is basically a variant of the actual EZ book with some interesting differences. First of all, it has the fingerprint sensor.
Then it has a better power adapter with changeable cord and the electronic seems to notice the charging status but no fast charging. (red and green charging lights.)
It still uses the Toshiba EMMC.
Not so nice is that it only has 4GB of RAM and the left USB port seems to have problems external drives. The AC Wlan has range problems as well.

Would be nice to combine some features to a new advanced version^^

 

BTW, did you find any reasons for the bad range?

Yep the battery is connected with a standard plug, I know what you mean about replacing vs a new notebook but if it dies prematurely it should be easy enough to fix.

I know, right? it seems odd. And the heatsink actually has exposed cut outs in the insulation above the WiFi and chipset as if it was designed to have thermal pads but they are missing. If you wanted to add them the 0.5mm size would be the way to go. I plan on adding them as well as a 1mm pad between the heatsink and the back of the case.

I was thinking about combining features too 🙂 I haven’t been able to find a trackpad with fingerprint reader that will fit yet though.

As for the WiFi range issue, it is because the antennas are routed in the black plastic hinge cover (in between the screen and the keyboard) but they face down and have very little exposure. You will actually get better signal strength with the lid closed than open. I haven’t come up with a solution yet but it is tricky because the whole body and frame is all aluminium. If the LCD surround was plastic that would be ideal. Right now it is really important that the screen is facing the router to get a signal, if you are sitting the other way around it does a good job of blocking it.

Hi Simon, and thanks for a photo reportage.

About the wifi, it’s possible change the adapter (maybe a mini pci-e model?) with another one more powerful?

 

Thanks

I took off the thermal pad between processor and the heat sink plate. Put some thermal paste there and then thermal pad between plate and the laptops bottom plate. Thermals lowered maybe 5’C or so, from 61’C to 56’C when playing or running 3dmark. Nothing epic but just for fun. 🙂

The WIFI chip is soldered to the board. So no, not really. The Intel WIFI chip has a different position to the RealTek chip, you can see in my Intel model the position for the Realtek chip is unused.

Great to hear, 5 degrees is decent, and with longer stress tests I’m sure the improvement will increase 🙂

Useful photos. Thanks for clarifying re wifi card soldered one. Shame really because I think mine is faulty – would have been good if it had been replaceable 🙁

routing it under the keyboard seems to be the only option there is. i wonder how is it engineered around on other aluminium notebook.
