Welcome to abi!!!

So it lights up and powers on when plugged into the computer. Does it go to the docked screen? Or does it go back to the normal screen?

Yes, welcome apiske148. Keep in mind, until the ZVM is detected by the Operating System and have its driver load in Device Manager, it will not be seen by Windows or any software.

I would still try another USB cable. Power can easily work on a USB cable, but the data pairs may not. I would also try (while plugged in) moving the sync adapter around to see if you can induce any action of detection on the computer. Perhaps the sync adapter isn't working correctly or there are some bent pins.

Perhaps a sync adapter issue.... or even a battery issue. Can you try another cable again just to verify? Do you know of anyone with another sync adapter you can try?

Could be the operating system. Windows has a way of bugging out sometimes, it's possible that the driver may have become broken, and doesnt load. Theres actually many different reasons for this too happen. I'd say try it out on another computer, if it comes up youve got a software/OS problem, if not then youve got some kind of a hard ware problem. You may want to pick up a new cable, and if the problem still persists, the docking bay on your zen may be compromised, and you may need a new mobo.

It doesn't even work on an AC adapter, so I don't beilive it is an OS issue. If the Zen isn't even powered on, Windows won't see it to begin with.

Ryan, please take into consideration what the OP is posting in all posts and not just the first post:

Oh yeah, right. Didnt see that. How could it have changed from the time he made the post too when he made that one? If it worked at the time of the post, what happened that made the AC charger not work? If the AC charger doesnt work, then youve got a motherboard malfunction of some type.

And another thing, you keep saying "The OP" whats an OP?

Not sure exactly until we hear back from them. He specifically mentions "cord" and not charger, so maybe he is using the same USB cable with a power adapter as well, idk.

The USB cord coupled with a power adapter is an charger. There would be no difference in power flow between the two. The reason USB is so slow from the computer to charge, is because its only got a small amount of current that it takes from the computer. When plugged into a power supply it jumps to the right voltage, which would be around 4.5 - 5 volts of DC power.

There can be a huge difference. Many of those adapters are soley ment just to provide power and not specially for charging. Many lack the proper protection and regulation an actual charger would provide.

From the Zen FAQ:

Quote:
Per the USB specs:
USB 1.1 = Minimum supply voltage is 4.4v
USB 2.0 = Minimum supply voltage is 4.75v
Both maximum supply voltages are 5.25v and a current of 500mA.

Before the USB bus interface can begin charging a device (Zen), it must return a device identifier to the hub driver (or device driver). Once the hub driver has the returned information from the device (like power requirements, supported transfer speeds, etc.), it can then begin charging the device based on those retuned values. This process is called Enumeration. Until enumeration has completed, it may not draw more than 100mA from the bus. Once enumeration has completed, it can then begin drawing up to the 500mA allowed by the USB bus.

Whoa! Dear God, I don't like where this is going!

I really do hope OP comes back and explains the current problem a little better, and that he's not trying to use a USB charger on that thing!

From the sound of things in his last post, it could be nothing more than the battery had just gone dead and needed to be charged. The slow-flashing blue light backs up my suspicion.

And by the way: OP means Original Poster, or Originating Poster (as in, the one who created this thread).

And, Bobby: I believe USB1.1 devices are limited to 100mA power draw. USB2.0 devices can request and receive the full 500mA.

I hope so too.

A low power unit load is defined per 100mA up to 5 unit loads equaling 500mA. The full 500mA supply current is also available for one device if connected, provided it asked for this in its descriptor (high power device/port).
