Hi everybody,
we have a Groove Metal with a weird power consuption…
Do I have to ask for replacement? 
Bye!
please check what voltage is at the groove and what data rate is in use.
If data rates are basic and voltage is low, consumption could be that high.
Thanks Janisk,
wlan disabled… system reset-configuration just done… Always high consuption…
Temperature very hot just after 10 minutes…
then it has bad wireless. You can contact your reseller for details on further actions.
