I recently purchased a tf201 and dock through Amazon. I have been consistently encountering a problem where my tf201 will not wake up from sleeping or turn on while it is docked. The tablet functions exceptionally well on its own; I haven't encountered any problems. The keyboard functions normally while the screen is on, but once it is off, the tablet will not turn back on. The only way to get the tablet powered back on is to plug in the external charger straight into the tablet, not even through the dock. Once I plug in the tablet, I can unplug it in a matter of seconds, the tablet turns back on, and everything works fine.

Please advise.
