Screen won't come on. Please Help
it may be in a low power state, try a different usb cable and hook it up to a desktop computer (laptop ports are sometimes not powerful enough to charge the battery when it is in a low-power state). I had this exact same problem and that fixed it!

Problems Charging, Turning On, or connecting the Zen to a computer, or upgrading firmware; Here are some things you can try:
1. If the Zen won't turn on,
try using a wall charger (like the Motorola Razor) and see if it comes
back on and begins charging. Wall chargers sometime will be able to
output more current than the USB ports of a computer resulting in
faster charging. Sometimes it is enough to turn it back on. Don't just
try any wall charger though. You don't want it outputting too much
power to the Zen and causing electrical damage. I would not go above a
5v charger for this since 5v, I believe, is the input power limit of
2. If the Zen won't turn on or be recognized by the computer,
try a hard reset by inserting a paperclip (or something like it) into
the small "Reset" hole on the bottom of the Zen. Wait for it to rebuild
the library and try again.
3. If the Zen is not detected by the computer when connected,
try booting the Zen into Recovery Mode (See directions above) and do a
"Clean Up". Wait for it to rebuild the library, do a hard reset and try
4. If the Zen is not detected by or charging from the computer when connected,
make sure you are using a USB port on the back of the computer (built
into the motherboard) instead of one wired to the case (front or side).
That way you are using a USB port with the proper power output.
5. If the Zen is not detected by or charging from the computer when connected,
make sure the USB port you are using are USB 2.0 and not v1.1. If you
computer is a newer computer, this shouldn't be a problem, but if it is
an older computer, it may only have USB 1.1 ports which doesn't output
enough power as USB 2.0 ports.
6. If the Zen is not detected by or charging from the computer when connected,
make sure you have no other USB devices plugged into the computer
(front and back ports), but the Zen. That may be worth a try to see if
you can get enough current from the USB ports to begin charging it
again. Usually the more devices you have plugged into the USB ports,
the less current that will be available for charging due to the power
being shared with all other devices plugged in.
7. If the Zen is not detected by or charging from the computer when connected,
make sure that the drivers are loading for it properly under Device
Manager (no conflicts showing). I believe the Zen will not be detected
or begin charging unless its drivers are loaded and working properly.
Storing or not using the Zen for long periods of time:
Lithium-ion batteries (by
themselves) with no built-in voltage monitoring circuit have a really
low self-discharge rate (1-2% a month) when not being used. Having the
addition of voltage monitoring circuits will slightly increase the
discharge rate, but should not reach the point of excessively
discharging the battery to where it won't turn back on unless sitting
unused for an extended period of time and if its last state before
powering off was a already in a low voltage state. So, as long as you
aren't storing it for long periods of time at a low discharged voltage,
the battery should be ok to recharge.
