Chosen Solution
Yoga 370 by Lenovo requires the battery to be disabled before opening the case. None of the guides here mention that fact!
Direct from User’s Manual: To disable the built-in battery, do the following:
- Turn off your computer and disconnect the ac power adapter and all cables from the computer.
- Turn on your computer. When the logo screen is displayed, immediately press F1 to enter ThinkPad Setup.
- Select Config ➙ Power. The Power submenu is displayed.
- Select Disable built-in battery and press Enter. © Copyright Lenovo 2017 93
- Select Yes in the Setup Confirmation window. The built-in battery is disabled and the computer turns off automatically. Wait three to five minutes to let the computer cool.
