On-screen keyboard duplicate presses while charging

When my daughter first got the NC I filled out the configuration screens while it was charging and noticed that the on-screen keyboard was acting flakey, sometimes sending duplicate keypresses. At first I thought there might be a hardware defect, but after some Googling I came across some info that indicated that the problem only occurs while charging. Sure enough, I unplugged the cable and the on-screen keyboard seemed to work fine. I couldn't seem to find any info about this in the forums here, but I saw another mention of this issue online where the author suggested that the problem was later fixed by B&N with either a hardware or firmware change. Does anyone know anything about that?

My daughter's NC has a few days left on its 14-day return window but when the eBay deal popped up, I took advantage of that. We now have the new unit from the eBay purchase delivered and I've left it in the sealed box. I'd prefer to be a nice guy and just return the sealed unit to the local B&N store so they can still resell it as new, but if there's a chance that the unit she's been using is an older hardware revision and the eBay unit might have a newer hardware revision, I'd prefer to keep that one.

If there are newer hardware revisions, does anyone know if there's any way of knowing which revision you've got based on the serial number?

No replies?

Well maybe I know why no one is replying. Last night I plugged in the NC to charge and saw a message stating that it was updating the OS to a newer version. Today, I tested the on-screen keyboard while it was plugged in, and I didn't see any missed/duplicate keypresses. So I'm thinking this problem was probably fixed with their last firmware update.

Glad the update solved your problem but I noticed a similar issue with mine. While plugged in, the slightest movement where the cord plugs in causes the screen to light up and the 'n' to switch back and forth from green to orange repeatedly. Not a big issue if it is just sitting on a table charging but it makes it almost unusable while plugged in.

A couple of updates...

I noticed that my receipt from the local B&N has the serial number of the unit on it. I figured this would be an issue if I tried to return the newly purchased (and still sealed) unit, so I swung into the local store to ask about it first. Sure enough, the unit's serial number would need to match. No big deal for me (other than the fact that I wasted a trip to the store), but kind of sucks for them since they'll now be getting our original used unit returned to them. I explained the entire situation and they seemed appreciative of my desire to help them, but store policy is as it is.

So when I got home I cracked open the new unit, and set it up to charge. I wanted to make sure everything looked good and I could easily re-download the one book we've purchased so far without a hassle. For simplicity's sake, I figured I'd just pop out the accessories box from the new one and put that in the old unit's box for return purposes. That proved to be a bit of a pain as the little box was stuck and eventually I ended up ripping that little tab off. Oh well, I eventually got the box out.

Next problem: The original unit's charger didn't fit right in the new NC. Weird. I immediately worried that maybe this new unit was defective. So after trying a few times (unsuccessfully) to get it to fit, I opened up the new unit's accessories box and tried that cable. Sure enough, it worked fine. So it seems that there was a hardware change of some sort, but I don't know which of my two units is the newer revision. FWIW, they both came with v1.0.1 of the OS/firmware. There's probably a way to tell based on the serial number.

Update: Based on Pre-dawn raid's comment, I went to see if I could fit the new charger in the old unit. It fit fine, but wiggling the charge cable caused the unit to get confused about whether it was plugged in or not. Then I plugged in the new charger to the new unit (which was a bit tricky at first - it definitely seems like I had to insert it "just right") and when I wiggled the cable there, there was no change on-screen. So I'm guessing that my newer unit and charger (purchased on eBay) may be the newer hardware revision. It would also make sense that this would be the newer revision since the new charge cable fits the old unit, but the old charger does not fit the new unit. If part of the "fix" required changing both the NC and the charging cable, then it would make sense that they would want the newer cable to still be able to fit the older units, since existing NC owners (of older units) might purchase a new charge cable from them later, and it would need to be able to fit.

Of course, it's also possible that none of what I've surmised is correct and instead that there's something slightly defective about my particular "newer" NC such that the older cable I had couldn't quite fit into it.
