Has anyone else had issues with their calculator not going to sleep after ndless 3.1 was installed on the CX?

Yeah, for me it's working from time to time....

I want to uninstall/reinstall to see if the problem is fixed, but I have not seen anything regarding whether the uninstall works right or not.

You can uninstall Ndless safely by running ndless_resources

are there any libraries to communicate with external devices

USB is not yet supported, but you can directly interact with the UART for RS232:

After I uninstalled ndless and deleted the resource files, the calculator begun to go to sleep again and the screen dimmed properly when it was supposed to. However, after I reinstalled ndless, the problem returned. The screen will only dim sometimes and I don't think the calculator has ever gone to sleep since.

 I suppose I could uninstall and than reinstall ndless whenever I need it, but I think I'll be using it too much to make that solution worthwhile. It's not really a big deal anyway; I just don't want to forget to put it to sleep and have my battery drained right before a test or whatnot. Hopefully the author(s) takes note of this issue and looks into it while developing the next version.

By sleep, do you also mean it never turns OFF by itself and won't go in standby mode anymore when not used for an extended period of time?

Welcome to the forums by the way.

Thanks for the warm welcome, DJ.

To correct my earlier post, the calculator won't enter POWER STANDBY mode anymore when it is not being used. I have not yet checked to see if the HIBERNATE function works or not (I'm assuming this is where the calculator actually turns itself off by itself without closing programs or documents, essentially sleep mode). The auto dim function has worked on and off for me during the past few days. Right now it's working, while earlier it wasn't.

That is also a good habit you talked about and one I should get into, though I am still nervous that while living the hectic life of a college student I will forget to turn my calc off manually from time to time. =O

Were you using OS 3.1 before ?
I can't be sure of what I'm going to say but maybe it is a clue : when connected to the PC, the Nspire won't turn Off automaticly (true) whereas unplugged it enters standby (IIRC).

Remeber that your Nspire (any model) can is powered by USB (you can remove the batteries/accu if you wish check).

my calculator does dim and stand by properly most of the time
once though i think it wasnt going to, i oppened the case about a half an hour later, it was dimmed but not standing by
that was only once tho...

Hm, mine sleeps fine everytime.  I've confirmed that. I don't think I've ever had it where it didn't sleep.
