Sluggish to turn on

I recently lost one of my programs and reloaded it back on to my calculator, ever since then when I turn it off and then press the on button again it takes about 5-10 minutes to turn on. Also when I go into the file manager the same thing happens except it takes alot longer to reach the file manager page..... I have reset it, i have reloaded the operating system, i have cleared the memory and tried it with no programs on it at all and still the same thing happens.... Any help would be greatly appreciated, cheers Joe

Re: sluggish to turn on

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.

I've had my ti-86 for a very long time & recently it just quit working. I changed the AAA batteries & the back up battery & it will not come back on. Please help???!!!!

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. Does it?

IT-86 Both batteries removed, now dead

Use the TIconnect or TIGraphlink software to reinstall the programs. You will find the programs in the TI Program archives.

Hope it helps

sounds like your backup battery is dead.. and maybe the clear or del key stuck down as either way it could wipe the program.. The solution i think is to hit the TI website and get the software reload and directions to reload it from there.

Well i suggest calling Texas Instruments
The chances of this happening are rare, but the back up
battery probably died. This could probably cause data loss
and you might lose the program and function data. Call and ask
to see what you could do.

Err: bad address when unarchiving

Ti helper has a correct answer but you may want to try garbage collecting first. To do this press 2nd catalog and then g and then press enter when you find garbage collect. Then enter again and say yes. This should give you back the mem if not you need to reset the ram.
