Hi,

A brief reintroduction:
I'm BigBubbaX (or used to be, I've since dropped that moniker for 'ctag'). Back in middle school I joined this community and was inspired by the hardware hacks being discussed for TI-83+ calculator. I tried modding my TI-83 and while the calculator didn't quite turn out, I learned a lot So, to those of you (Kerm Martian) who patiently put up with my antics a few years ago, thank you.

I'm now in college, and am just taking the first class which allows a calculator to aid in homework and tests. Unfortunately, the TI-nspire that I had purchased in high school has.. Issues.

~3 years ago: I purchased a Ti-nspire and rechargeable battery for it. About 6 months later, the rechargeable battery stopped charging. TI told me to "buy another battery", so I did. The battery arrived and wasn't used because the calculator wasn't needed for class.

Last Week: I found both the calculator and the batteries. Neither will charge. I've tried charging from a desktop computer and from a cellphone USB charger. At the system status screen, the OS says that the battery is charging and is currently at 0% and never increases. While unplugged, the system will whine constantly about how low the battery is, but doesn't crash or lose power. I've tried resetting the system from the button on the back, no dice. I'm torn, to me it looks like it could be a hardware problem, or it could be a software problem. I decided to try updating the OS. Unfortunately, my student software that came with the calculator is long gone, and when I asked how I could retrieve the software to update my calculator I was told to "buy another license." No big deal anyway, because I don't have a computer with Windows on it anymore, and Ti doesn't seem to support Linux at all. So I installed TiLP-2 (1.17).

Well, TiLP crashes while trying to copy over the 3.6.0.546 firmware (currently running 3.20.1219). When I start the transfer, the calculator screen reads "Transfer failed. Check the connection and try again." and TiLP reads:

"Msg: hand-held returned an error (not caught).
Cause: hand-held returned an uncaught error. Please report log."

I'm not too sure where to begin troubleshooting. Should I try fixing the connection with TiLP and pray a firmware update will magically fix everything? Or should I eat the cost of both batteries and just waste more money on AAAs?

Output of TiLP when run from a shell:

Code:


Some basic troubleshooting came through :-\ I searched the error code, a post in this thread mentions 0x08 being battery related. I hopped out and bought some new AAAs, and the system is upgrading

Thanks,

Welcome Back! You should certainly Introduce Yourself! (Again?) Hopefully you plan to stay! We do several community activities that is unrelated to programing. Like, Unreal Tournament 2004!

Glad to read that you got it resolved! Hopefully this will prove useful for anyone else that has a similar issue.

Thanks comicIDIOT,

-*- Yeah, I do hope to stick around. I just re-read the AboutUs page, since I remembered Cemetech=calculators but not much else. I'm currently working on plans to build a laptop in about a month here, I'd love to gauge this forum for support/interest in such a project.

The calculator successfully updated, but still doesn't charge, so I'll keep the thread open while tinkering with it.
