Hi,

My OSTC Plus being locked, I had to remove and reinsert its battery ; this is the original 3.7 V rechargeable lithium battery.

When the computer starts (firmware 3.00 and later 3.01), I choose "3,6 V chargeable (T2)" - in fact 3.7 V. Then the computer indicates 99% but the voltage is only 3.0 V, meaning the battery is almost empty.

I put the computer on its inuctive charger, it is detected, charging starts and the green led ligths. But after a few seconds, the red led flashes and charging stops.

Any idea of what is wrong ?

Hi Didier,

Power supply sufficient? It should be at least 1.5A at 5V. In which circumstances did your unit freeze?

regards,
Matthias

Hi Matthias,

Thank for the advice : the charger was connected to a USB port of a laptop probably not able to provide enough current ; once connected to another power supply, charging looks ok.

This is strange because from the beginning (more than one year) I always used laptop USB port with no trouble ; maybe this time the battery was too deeply discharged ?

A last info : the unit was locked in dive mode (cf. our private exchanges last week).

Kind regards.

An OSTC that is active, i.e. with screen (and hence backlight!) on, will draw more current from the charger compared to charging only while in sleep mode...
