Chuwi HiBook Pro swollen battery, screen and case gap

I would not use it, try to discharge the battery and see if you can get a refund/replacement unit. That should not be happening. So glad I never got a Note 7, I was so close but decided on some review units instead.

Hi Chris,

Sorry for the hiatus. Opened up my HiBook myself. Banggood offered me to ship back to repair or a refund of USD30. Both didn’t look good, so i decided to open it up and have a look. Seems like the cells were alright. Didn’t get to test the voltages though as i didn’t have the tools to do so.

Now, it seems that the USB C ain’t charging the device. Cos even it i broke the screen upon opening, there should be a red indicator light for charging.

Regards,
Wei Xiang.

Wei Xiang.

Thanks a bunch for including a high-resolution photo of the “guts” of your HiBook Pro. Did you ever resolve your charging problm?

Could you give us a summary of the disassembly procedure? How did you pry the case apart after removal of the 4 Torx-4 screws? I’m eager to upgrade my WiFi antenna and see if I can improve the wireless performance, and luckily your photo shows the (single) WiFi antenna, and also that there is room for another. Now, if I can just find the connections on the PCB…

Edit: I finally ran down the data sheet for the Realtek SDIO WiFi module (RTL8723BS, also known as the SM02BS Combo Module) and I’m giving up on the dual antenna idea. The reference design on which the WiFi module is almost certainly based on the one below and the datasheet really doesn’t have enough info to do dual antennae. Note that in the schematic, inductors are labelled as capacitors, etc. A bit scary…
