My tablet goes dead when i play games while it is hooked to my laptop to charge via usb because it seems it doesnt get sufficient energy to spare. When the tablet is hooked to the usb transformator tht is plugged in 220 wall socket it seems its ok...
my question is is this normal?
For me it seems illogic since usb current should b the same .

    PC/laptop USB : 5V 0,5Ah (international standard)

    AC charger : 5V 1Ah (you can find chargers up to 2Ah)

     

    you can easily understand that you have more Ampere/hour (Ah) using the AC charger.

    So....this is normal.

    I'm not if you just have to get up to a certain threshhold or if there's a timeout for editing posts ... but

     

    yes, it's normal. Many people who have been investigating these bahaviors have found that hooking up to a USB port on a computer gives just enugh juice to keep a table charge under typical usage. To charge while using the tablet you should be connected to a carger instead.
