    Samsung GT-P5210 10.1 inch Tablet repair

    Hi,

    I have a Samsung GT-P5210 10.1 inch Tablet and it doesn't work. It doesn't charge and it doesn't switch on.
    I tried following:

    Reset it by pressing power and volum up OR down button simultaneously, it didn't show anything.
    Leave it connected to charger more than one day. It didn't show anything.

    I measured battery voltage, It shows 2.3V, yes it ist not good, but even without battery and plugged to charger, it doesn't show anything.

    I connected it to Ubuntu laptop with USB cable, dmesg in Ubuntu shows some messages:
    usb1-2: Manufacturer: Intel
    usb1-2: SerialNumber: XXX

    I measure the voltage and current on micro USB input.
    It draws ~20mA less than 1s and then it stops drawing current.
    I think there must be some short circuits but could not locate it.
    But even if there is a short circuit, then USB functionality should also not work, laptop shows some messages if connected.

    What can the problem be?
    Can I repair it?
    Thanks.

    It's essential that you measure voltage coming from the charger when it's plugged into the tablet. It may not be easy to find suitable test points.

    Sometimes I stick pins through insulation and attach my meter. (But avoid sticking pins in shielded cable since you could short-circuit the shield to inner wire.)

    Measure in all situations:
    * Battery pack installed
    * Battery pack removed
    * just as you turn on the tablet
    * 2 seconds after turn-on
    Etc.

    I have an USB volatage meter and connected USB cable to this measurement device.
    Like this one:

    I charged the battery from a charger circuit externaly and put it in the tablet, still same.
    I think motherboard of tablet is damaged.

    Question: Is it the type of battery which should not be allowed to drop below a certain voltage? Because if it does then its useful life is over?
