Hi,

I got an issue when charging my jolla tablet. Once I plug the power the battery start to charge. But if I let the tablet during some time it become unresponsive and drain the few it charged. Even if the battery was 40% before charging I can find it completely empty.

I encountered the same issue when the tablet is ON or OFF before charging it.

This problem occur more and more frequently. The tablet becomes unusable....

Just in case I tried with 2 different power supply but still the same issue.

Same problem here. I hear there is a contact problem with the usb plug. I also tried different cable and charger. No i will try to replace the plug ..

Is there any tutorial about how to open the jolla tablet? Just to check if it is really the plug.

But it does not explain why the tablet become unresponsive after a while with power plug in. I have to press the power button more than 10s to wake up it, sometimes it works, sometimes not...

@AmaudD: I did not have a tutorial. I got some pictures from @ExPLIT (https://together.jolla.com/users/4887/explit/) you should contact him for the pictures .. He post his email address on some answers.

The freezing of the tables is a new problem on 2.1.0.X i think. I also have it. A work around for me is to power off the tablet before plugin the charger cable carefully. To see weather it loads or not, i make a short press on the power button after a while. I'm not shure that it also is not a result of a contact problem of the USB plug. May be the attached cable interrupts the system to often for the decision about usb mode to use?

Effectively the issue was coming from the USB plug. The small black part inside was able to move a little bit. One of the USB wires was surely broken and randomly lead to contact failure but sailfish always believed the hardware had external power.

I've able to find a replace part and now it works perfectly. Thanks gabs5807 for the tip. Opening the tablet was not hard.

Edit: As requested in comments I used this replace part: http://www.komposantselectronik.fr/prestashop/connecteur-micro-usb/754-connecteur-micro-usb-b-femelle-a-souder-fixation-4-points-ecartes-90central-5-points-pour-l-usb-pattes-courtes.html . Sorry but I don't have any "official" reference, neither a vendor name.
