I've had this problem twice already, and it occurs at the same time.

After finishing browsing the internet with my DSi, I go to turn/reset the console, and the unit freezes - displaying a blank (but lit) screen. The power buttons do not work at this point, and I am forced to drain the batteries so the DSi turns off, and I can get it working again.

The first time it happened, I pressed the power button while it was trying to load a page (but with a combination of large file size and sluggish internet connection - nothing doing), and then it displayed that blank page. I had to wait for the battery to run down.

This time, the page had finished loading when I decided to turn it off and the same thing happened - blank (backlit) screen, power button not responding, and I'm forced to let the batteries run down once again. If I recall, they were both different websites where this has occured.

I've never had a problem turning off the DSi after first navigating to the DSi menu, but I'm a lazy person and sometimes I'd rather reset or turn off my DSi with a single button press. If this a common issue, I suppose this may act as a warning to others, but I'd like to know if anyone else has witnessed this issue.

I do that all the time and it never happens to me.
That's kinda weird.

That's odd, thankfully that doesn't happen to mine. Try deleting the browser from the system, and re downloading it from the shop channel. If that doesn't work then I would contact Nintendo about it.

Ummmm...
Yeah what he ^ said!

Its frozen a couple times on me after coming out of Base 10 but one more press of the power button boots me to the menu fine. I doesn't sound nearly as severe as your problem. I'd call Nintendo.

You should't have tio drain the batteries in fact get a simple jewellers screwdriver & remove the battery for a second just quick enouth to turn the system off but not long enouth to reset the clock thats if its possible with the DSi
At least this way you don't have to wait for hours for the battery to drain .

Well, I was going to say my battery shouldn't have much more to go (I turn the brightness up and it drains quicker), but the battery has run out, so no worries.

In the future I will definitely be turning the unit off on the menu rather than the browser.

(I'll keep your tip in mind as well, In case I accidently do it again.)

I actually agree with a previous post. Delete the browser- download it again. If your connection is bad there is a chance that a file for the shut down sequence is corrupted when you got it. I would recommend downloading it from a place where you know there is a good connection. Sometimes I've noticed that things wont go so well if I download them from a bad connection on my computer. Perhaps the Dsi is the same way?

Well, the DSi freeze happens when you go into an app then jump right back out the same time. In the browser's case, it is slow returning to the DSi Menu.

The ultimate best thing to do is to crank up the brightness level to 5 and drain the power. It happened to me like 3 times already.

(And yah, turn off the DSi from the menu, the browser does not do it justice. )

I would love to contact Nintendo about this and another problem: (off-topic) Why is the stylus in the holder so loose? It somehow falls out.... a lot.....

have you tried holding down the power button until it shuts off, and then turning it back on? that works for me when i want out of the DSi Browser in a hurry and don't want to wait for it to get its slow self around to loading the main menu again.
