Protip: Connect the internal JMB363 SATA connector towards the rear of the motherboard to an eSATA port bracket and ignore the integrated eSATA port to avoid both of the following problems.


Lenovo Yoga Book Android YB1-X90F bootloops instead of charging

Sunday, April 19th, 2020

If, after powering off suddenly because the battery was completely drained, your Android Yoga Book is doing the following when plugged into the charger:

  • Continuously restarting to the Lenovo logo and then a battery charging icon
  • Apparently not charging

Do the following:

  • Leave it plugged in.  It’s actually charging even though it doesn’t appear to be.
  • If the bootloop and vibration is annoying you, press and hold the power button for about 30 seconds; after going through two more bootloops, the system will proceed to boot up fully.

If that doesn’t work (for example, if the battery is at 0% and the system cannot boot:

  • Hold Power + Volume Up simultaneously until the bootloader appears.
  • Use the volume key to select “Recovery Mode”, then press the Power button.
  • After the system enters recovery mode, just let it sit while connected to a high power (i.e. QC wall) charger.  There’s no indicator that it’s charging while sitting in recovery mode, but it is.
  • After a few hours select “Power Off” and restart the Yoga Book.

That’s all!

Autonomous SmartDesk with TiMotion TC15 controller doesn’t move

Sunday, April 19th, 2020

Okay, this will be a short post.  If your adjustable desk won’t move and it has the TiMotion controller, do this:

  1. Unplug the controller until the green LED goes out.
  2. Plug the controller back in.
  3. Hold the up and down buttons on the front panel simultaneously for 3 seconds, or until the motor relocates the base to the bottom and beeps once.

Then your desk will work again!

Here are the specifications and user manual.  For reference, I verified the power supply board provides 32VDC to the controller board, and the controller board provides 5VDC to the motion base motors.
