Temporary D-pad Malfunction = almost-brick?
I'm sorry if this isn't the correct section, I looked around and didn't see anywhere else to put this. Just a few minutes ago, my Wii remote had lost some functionality after i had let it sit for a while with a game running (the remote had turned off, as usual after however long). When i turned it back on, i found i could not move my character anywhere (which is normally done using the D-pad [New Super Mario Bros Wii]). This didn't alarm me much at first, because the Hard Drive I'm running the games off of has a problem with the USB cable, and if it is moved much it shuts off or whatever. So I figured that must have happened, and i restarted the Wii, loaded the game back up - same thing. I started to get worried. Restarted Wii again, loaded up Mario Bros (a virtual console thing - actually paid for it, NES). I had almost no control over D-pad and the + button (at least, these are the only ones used.). I plugged in my Classic Controller to start the game. I could not move sideways unless i had jumped, which is odd. I then tried Zelda (another VC - paid for, NES). The D-pad Seemed to be stuck with the left (down when sideways) button pressed down. Link was always running down, however i could move sideways but not up. I tried re-syncing my the Wii remote, however nothing had changed. I was going to take apart the remote (no reason why really, just felt like it may help). But, as I do not have the trigram screwdriver, I got 2 screws out and gave up. I put the batteries back in, and re-synced again. I opened the Internet channel, to see if i had D-pad functions there, which i did. I then installed another VC game (a demo, pokemon rumble - just wanted something free + quick). I played it for about 10 seconds, found I had full functionality in the D-pad, and exited. Mario (VC NES) worked after this, and so did NSMBW.
Can anybody tell me what exactly may have happened? Was this some sort of miniature almost-brick or something? Sorry if that was hard to read, and included WAY too much extraneous information, but I wanted to make sure I had everything in there. Sorry again if this is in the wrong section, but i got pretty scared when this happened, and would like some reassurance that it was either a fluke in something, or just an unlucky set of events that rendered the Wii remote dysfunctional temporarily, and couldn't find anywhere else to put this. Is there anything I should do to prevent this from happening again?
Thank you in advance.
