Einleitung
Diese Anleitung ist mit allen Varianten des TI-84 Plus CE und TI-83 Premium CE kompatibel.
Die meisten Probleme lassen sich mit mindestens einem dieser Schritte beheben, allerdings können dabei Daten im RAM oder ROM (Archiv) Ihres Rechners gelöscht werden. Um Datenverluste zu vermeiden, sollten Sie eine Sicherungskopie Ihres Taschenrechners auf Ihrem Computer erstellen oder alle wichtigen Informationen archivieren.
Bitte beachten Sie, dass jeder Schritt eine eigene Lösung darstellt. Sie müssen nicht jeden Schritt ausführen, wenn Ihr Rechner wieder funktioniert.

My calculator has not turned on for the past week. I have tried multiple USB cables and power sources, a (charged, working) battery, the On+Ac+Reset trick, and all of the techniques mentioned in this guide. The calculator still displays nothing on the screen, and windows, Ubuntu Linux, and MacOS all refuse to recognize the calculator. Drivers can’t be installed, and I even attempted a jerry-rigged USB connection using a few alligator clips (bypassing the usb connector in the calculator). Any advice? I’ll take any at this point.
@the_pimaster Ok, just checking, you do have a TI-84 Plus CE? There are similar calculators out there that have different key combos. Also, what do you mean by On+Ac+Reset? The correct combination is [2nd]+[del]+Reset. I’m surprised the computer doesn’t even recognize the calculator is connected, does the LED by the USB port turn on when you connect it to power? If so, what color?
What were you doing when the calculator was last working? Did you accidentally spill something on it, drop it, or crush it?
@thelastmill Thanks for the quick response! Yes, it is definitely a TI-84 Plus CE. I just tried the 2nd+Del+Reset combo you mentioned, but still no response. Something interesting— The calculator is not showing up in Windows’ device manager nor in driver installation menus (“Unknown USB Device”) but unplugging/re-plugging or hitting the reset button triggers the “new device” sound in Windows 10. When I first plugged in the Calc, the Light by the charging port lit up red. After 2-ish hours charging, it is now green— I am aware that the battery/charging circuit is seperate from the calculator itself, which may be the source of this issue. The calculator was working last week during a math test, during which the screen turned black. The battery was charged to ~80% at the time, and the device was sitting on a desk— no physical damage occurred, and the calculator is only around a year old.
@the_pimaster Sorry it took a lot longer for this one. I’ve been asking some of my friends about this and unfortunately I think your best bet is to contact TI. I’ve never seen a calculator just… die like that before and it’s quite confused me; if I find a solution I’ll be sure to notify you. For now though you can email them at: ti-cares@ti.com or call 1-800-TI-CARES (toll free). I apologize I wasn’t able to help you with this, if TI somehow gets it working again, please inform me how they did it!
So I have an issue, my calculator has had its battery light charger indicator on forever until it dies, that was 4 months ago. Since then I have been constantly having to charge it when I use it since the battery lasts for 2.5 hours off a single charge, but unfortunately, the darn thing would not turn on last night. I have tried every cable, nothing works.
Now for my what I think happened was that I used the wrong wall plug which destroyed the capacitor. Any advice?
