android tablet not waking up I've got a cheap android tablet running Android 4.0.4 and it doesn't seem to be "waking" up when I want it to. So, when it shuts off after period of inactivity or when I put it to sleep (not powering it off, though), it won't "wake up" at a specified time via the built-in alarm clock or another app (like tune-in which has an alarm feature built into it). When I manually "wake it up" by pressing the power switch, the alarm that should have gone off before goes off after a few seconds.

Do I just have something disabled that is preventing it from waking up? Or is this possibly a hardware issue?

There's no user-visible setting in Android for disabling alarms. That would kind of defeat their purpose!  The only way you can have disabled alarms is if you've rooted the device and gone around uninstalling system apps or poking at the internals. If you have, we'd need to know a lot more detail on what you've done to know if that's the cause, and the fix would probably be to flash a new ROM.

This does sound like the kind of system integration error you might find on an incredibly cheap tablet. Not quite a hardware issue, but a bug in the device's software. If it is, the only way to fix it would be to try to get an update from the manufacturer, but if you don't even know who they are, you might be out of luck.
