Power ON Problem Running on the Battery

Post by mikejensencomputing »

My OS3 is nearly new.

I have noticed that the unit will not boot up when powering on with the battery only.

After pressing the start button, there are lights on the unit initially but they stop after a second or so and the unit dies. The battery is nearly fully charged .

This problem does not appear when running on usb power, the unit powers-up fine.

I have tried various durations of button presses but the unit behaves in the same way.

What happens if you power on the unit while it's connected, then unplug the USB cable?

Yes, in that case the unit just carries on working.

It's just the power-on that is the problem.

Can you turn off the unit with the power button?
Is the device running the latest firmware? (v55)

Thanks for coming back to me.

Yes to both questions.

One thing I did was run the battery out then do a full charge.
After that the unit is powering-on by button press quite ok.

My OS.3 is now a lifeless brick.

It will not power on, with or without the charger attached.

There are no lights on the unit at all when the charger is connected.

This happened after barely a day of use after a charge was performed.

It has no pulse :(

The firmware upgrade process probably got interrupted.

Please do the following to resume firmware upgrade:

1. Connect the openSPOT3 to a wall charge adapter or USB port on a computer
2. Press both the Wi-Fi and power buttons at the same time until the status LED lights up steady white
3. Release both buttons

The firmware upgrade process should resume indicated by red/green alternate status LED blinking. This usually takes several minutes. After the process is completed, the openSPOT3 will automatically reboot and you can continue using it.

If the previous procedure does not help, then please try the following:

- Press and hold the power button for at least 7 seconds
- Use a different wall charge adapter or different USB port on a computer to charge the unit
- Try flipping the USB-C connector of the cable upside down
- Do a factory reset by pressing and holding the Wi-Fi button for at least 30 seconds

Norbert thanks.

Well, the OS.3 has come back from the dead! I put it aside and later in the day tried to power it up, and this time it's lights came on, it booted, and is performing as expected.

I did nothing to fix the problem and I didn't need to follow your instructions you gave, it self-repaired.

I am not sure if the root cause of the problem is known though.

It could be a slightly dodgy contact between the battery lead connector and the PCB battery connector, several people have found that carefully lifting the top of the case away (mind the WiFi antenna and cable) and gently pressing on the battery connectors will make the connection more secure.

Check that you locate the buttons correctly when replacing the case, they can get trapped under the edge of the holes.
