    I use a Tablet to carry lots of PDF files around, I find it quicker
    than booting up a laptop..

    This morning I got into the car and I had left the unit powered on
    from yesterday, screen pops on reporting a low batter, I think below
    20% or something.

    Any how, it must of messed up something because when I got to work this
    morning, I decided to fully power it down and bring it in with me for a
    full charge. When I looked at it, the screen was no longer on, the
    active light was not on however, the low batter light (orange) was on.
    and this is with no AC power to it and I had no control over it at all.
    in other words, the unit is sitting there dead with the low battery
    light stuck on with nothing in the remote power jack.. how quaint! :)

    After a couple hours of charging attempts today, it didn't seem like
    nothing was happening. So I left it unplugged. Tonight, when I come
    home, the damn orange light is still on but no control over it.

    I just love how these chinese engineers design power management.
    It appears something has locked up in the power monitoring part of
    this unit or, it is forcing me to perform a trickle charge.. I may need to
    pull the batteries and reset it. which by the way, I learned tonight
    what that lock button is now for on the upper left corner, to remove the
    back cover :)

    It's simple, you don't read the manual until you run into problems!

    Any one ever see their tablet lock the low battery light on with no
    control ? I am thinking that maybe a stand alone uC system that my need

    You probably need to attach a charger directly to the "battery"
    (it's probably a single cell not a battery)

    That was going to be my next move however, I let it sit over night and
    the battery finally ran down low enough to turn off the battery low LED.
    Today when I got home from work, I looked at it and it was completely
    off this time, I plugged in the charger and I got a momentary power on
    light and then the low Battery LED popped on, so I assume things have
    reset themselves and the unit should be charging now.

    This all happened when the unit was left on and when I got into the
    car the vibration sensor triggered the screen. But it was in a dim
    light mode but I saw the battery report was very low. I think the unit
    didn't have enough power left in it before I was able to properly shut
    it down and it went into a lock up..

    Removing the battery most likely would of fixed it. Well see if it
    still lives when it's on the charger for a while.

    I think now is the time to make a copy of my PDF and image files I
    have accumulated on it.
