How do you open tensorbook case

[j_molineux]

I have an older Tensorbook laptop. Recently it has started having problems booting. I suspect the CMOS
battery has failed. I tried to remove the back cover by removing the screws and gently prying. The case
gets hung up by the ethernet port and the USB ports. Is there something else I need to remove to be
able to remove the case? I didn’t see any more screws that might be holding the case together.

There are about 11 screws in the back. Then I gently separate around the edges of the case.
Placement is slightly different depending on which generation of the tensorbook 2020, 2021.

There is not a separate CMOS battery, to reset the CMOS.

1. Power off
2. unplug
3. Remove the 13 screws and separate around the edges. (You do need to gently pry them two halves apart and move around as it separates).
4. Unplug the main battery
5. I would hit the power button to just discharge any power
   Then:
6. Plug the battery back in
7. Clip the halves back together
8. Put the screws back in.
9. Power up
