What is the difference between Maestro versions A and B

What is the difference between Maestro versions A and B and how can you tell by looking at the unit?

    They are built around two slightly different tablets.

    The A version has the power button on the top left.

    The B version's power button is on the left side.

    I'm not aware of any feature differences with one possible exception:

    The A model, like I own, has an annoying problem that makes it boot up with no human interaction..

    Here's the scenario that I have actually experienced:

    1. The unit is off but the AC power supply is plugged in to keep the soft switch circuitry from discharging the internal battery while the unit is in storage.
    2. The AC power is interrupted then re-established.
    3. The unit boots up all by itself. <--- Nothing else I own does this.
    4. The AC power then goes down and stays off for a few hours which is long enough to discharge both the main battery and the tablet's internal battery.
    5. The next time you go to use the unit it is dead and can not be rebooted even with AC power.

    You then have to disassemble the unit and recharge the tablet's battery separately since the internal charging circuitry won't charge if the battery voltage gets too low. If that doesn't work then the unit gets a trip to Texas for service.

    I have been told that this doesn't happen with a B model. I have no first hand experience with a B model so I can't say if it fixes the flaw or not.

    My "fix" is to store the Maestro with AC power from a UPS so it's really not a deal breaker.

    Hi Lou, there are no feature differences between the two.

    @Bob K8RC thanks for the info, are there any major feature differences between the two versions?

    The B model I'm using booted all by itself today. I held the button a little bit too long when I shut it down. So I had to swipe the arrow down to complete the shutdown. But a few minutes later it booted up on its own. First time it's ever done that. At least that I'm aware of. As I don't own it.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
