I disconnected the battery of my Chromebook because the model (Lenovo 300e 2nd GEN) calls for it when disabling write protection.
When powering off the AC adapter, the charging indicator flashes red, meaning the battery is gone. However, the power indicator also flashes accordingly, meaning that the chromebook is technically boot looping. Throughout the process nothing is shown on screen.
The only time it visibly boots and is stable is when it boots into recovery mode after an esc+refresh+power.
