As the title says I have 2 switches showing the same symptom. One switch one lite
After quick investigation I found no short on usb c power of or video chip.
Initially the batteries was flat, after leaving it a while to charge they got full just fine. While charging the battery icon was not shown on screen. Using usb meter gave usual reading that is email@example.com, firstname.lastname@example.org during early and middle of charging cycle respectively
To check if the battery is charged or not I teardown the unit and directly probe battery terminal which gives 4.17 volt more or less .
Pressing power button doesn’t give any response, no sound or picture. Long pressing do nothing either
I am really confounded and hope gurus and masters here could point out possible fix
