Is there a website describing TI Nspire platforms?

Yes, the keypad doubles as battery cover. A very clever solution!

The idea was clever, but in practice it is sometimes problematic. It's not unusual for students to tell me that a key or the touchpad is not responding. Often, the fix is to remove the keyboard and reseat it with a bit of force which suggests a problem with the contacts. If that doesn't work, a paperclip reset often does the trick which suggests a software issue. Sometimes swapping keyboards with another calculator confirms that it's a physical problem with a key which requires opening up the keypad and cleaning under the metal dome or rubber membrane.

I have not had any such problems with the new Nspire CX or CX-II which have permanent keyboards.
