Simple and clear.

Have here one piece and it wont turn on too.

Have took from one man only usb board and the battery is charging. Put the charger off before minutes but the tablet still wont power on.

thanks.

 

Yes. Different amp-hour capacities. Voltage will vary depending on state of charge.

Battery voltage may be too low for the tablet to turn on.

Measure the battery voltage under load.

 

now i put to charge the battery again and the meter is showing increasing.

I begin to think that if there are 2 things to go wrong, by my side every time minimum 4 are going to hell and never can have success

 

What type of tablet is it?

 

Vonino
sirius QS internet tablet
;

 

3.693 and nothing. Maybe something with Power Key and its ribbon cable is wrong. Maybe lcd or digitizer connection...

I have break a little the ribbon cable of card reader but now the cable and the board of card reader are desoldered...have buyd new one but still dont installed them

 

Which is the next higher than 3.7V? /if the question is not silly/

 

So so

it`s me again.

Now measure the voltage and it`s 3.897.

Yesterday put the device on charge at 10:30(local time and every times above will be too)

At 12:30 4,16

When i left 17:40 4.15V

What can be the reason? Maybe this can help everything to goes in right direction(although my usual negativism)

Thanks and have a nice beer
