Recently my base model Surface Book 1’s original charger died so I replaced it with the SB 2's charger. Now whenever my...

It’s a long story, but I accidentally dropped my Surface Book Pen in the parking lot 3 days ago and only found it today....

Hi, does your computer recognize your calculator when you plug it in? If so, then there’s definitely a hardware problem with the screen and you’ll need to contact TI Cares to get a replacement calculator. Thankfully your calculator is still covered under the 1 year warranty. If you want, you can try to run a LCD self test to see if it changes your screen at all. To do this: (1) Turn the calculator on, then press [mode]>[alpha]>[s]. (If you’d like a video tutorial, I have one here.) (2) Then press [enter] 3 times. (3) Now press [1]. (4) The self test will start. Press [enter] slowly 8 times to cycle through each test. (5) Press [enter] one more time to quit. There may be a small chance that this is a software problem and I’d suggest following TI-84 Plus CE Recovery Techniques. just in case.

Sounds like you have the same issue as this guy: Certain buttons not working

Sadly no, even if the component is compatible with your calculator, TI has designed the OS to only use as much Archive space as the original FLASH chip. This is true for all TI 84 and TI 83 calculators as far as I know. If all you want is some more storage to offload some things, you can connect your calculator to your computer using TI Connect (not the CE version). You can then use your computer to store programs and things you're not using.

Reset the calculator by re-setting the battery. The number 1 will not come off of the screen

You can find replacement parts on places like Digikey, Aliexpress, and likely even Adafruit or Sparkfun. You’ll have to find a port with the correct footprint of course. If your port is too mutilated to tell, here’s some photos I referred from: top down view and close up. You’ll want a port that is 2.5mm and has 3 conductors and 3 contacts. I don’t have the dimensions of the original port, however with some quick research, I found this port which looks like it should fit. The only issue is the back contact doesn’t line up with the contacts on the PCB. You can likely just solder a wire from the contact to the PCB however, if you look at some of the sites I provided above then you may be able to find a more suited part.

First, check your battery, make sure it hasn’t corroded or damaged the calculator somehow. Next, I think your best bet is to try to re-install the OS. There’s a guide on that here: Texas Instruments TI-Nspire CX OS Replacement If that doesn’t help, try reaching the diagnostics menu or the maintenance menu by following one of these combinations I found on TI-Planet: 3) TI-Nspire CX/CM: (1) [esc]+[menu]+[-] (2) launches the diagnostic software, if present (non-dangerous choice) (3) [doc]+[enter]+[EE] (4) Goes to the Maintenance Menu (allowing you to delete the OS, etc.) (no effect if nothing if cancelled - not dangerous

It looks like you might be able to repair it, but since TI doesn’t offer first party parts you’ll either have to find a for-parts Nspire CX on Ebay or find parts on sites like taobao: https://world.taobao.com/item/1957647300... (cost about $14 USD). I have not personally bought from that site before, however it was provided by TI-Planet.org, a site well experienced in all things Nspire related. Before you go out and buy one, could you please tell me your calculator’s hardware revision? It will effect which screen you need to get. If you don’t know where it is, 'it's the few letters on the back of the calcualtor, to the right of the serial number. It looks like P-1115W, for instance, meaning hardware revision W''' Once you have a screen on hand, you can use this guide on iFixit, and this guide on TI-Planet.org to swap out the screen. Good luck!

I don't have a definitive answer, however this is off the top of my head: If it stopped working right after you put it back together, I'd suggest taking it back apart and seeing if you simply didn't put the enter key back together properly. You can use this guide if you need: TI-89 Titanium Power Button Replacement I'd highly suggest cleaning the battery corrosion while you're at it (there's many guides online if you need help with that)

Your calculators might be having a similar issue to the TI-84 Plus calculators where the ribbon cable is degrading. If you have soldering experience, then you might want to take a look at this guide here: Texas Instruments TI-30X IIS Battery Replacement for instructions on how to take apart the calculator. Refer to this topic on Cemetech for instructions on how to fix a ribbon cable: https://www.cemetech.net/forum/viewtopic...

Hey, does your screen happen to look something like this? If so, it sounds like you have the same problem as Broken pixels came back on my ti 84 plus ce LCD, can this be fixed?. If not, could you please post a picture of what your display looks like? It’ll make it much easier to understand what’s going on. If you’re lucky, the ribbon cable connecting the LCD to the motherboard may have simply come loose. If you remove the back shell you can try re-setting the ribbon cable. (refer to this guide for help with handling the ribbon cable) If those don’t work, then I know the display is a GiantPlus GPM1421C0 and the latest display is a GPM1607A1 (it doesn’t matter which one you get since they are interchangeable), unfortunately, I have no idea where you could buy one since I believe TI sources them directly. :( In order to get a working display, you’ll need to buy a broken TI 84 Plus CE(-t) that still has a working display and salvage the display out of that. Make sure not to buy a TI 84 Plus CSE since the...

You can’t buy replacement parts for either one without finding a donor calculator somewhere. If it’s just the screen protector that’s damaged then you can just pull it off since it’s only held on by weak glue. If your LCD is cracked then you’ll need to find another TI 84 Plus CE and swap the LCDs. Fortunately all displays are compatible with all hardware revisions so it doesn’t matter which one you get (just make sure you do NOT get a TI 84 Plus CSE since it does NOT have the same LCD).

@Infine Axel, I think this is the exact question topic you’re looking for: Why my charging light is always on? It kills the battery..

Oh no! What do you mean by “ when I pulled the screws, the screws came off the cover, like they are completely jammed”? Are you saying the screws on the battery compartment fell out? If so, that’s not normal. They should stay on the battery compartment.

Do you have any idea why your calculator could have suddenly died like this? How long have you had it? It’s possible it could just be defective.

I know you said it wouldn’t turn on, but perhaps you could try connecting your calculator to power then trying TI-84 Plus CE Recovery Techniques. ?

@forestguzman That’s not really an easy project. Perhaps there’s something wrong elsewhere in the calculator that’s easier to fix. Can you please tell me exactly what’s wrong with your calculator? Have you tried looking at TI-84 Plus CE Recovery Techniques. ?

For a project like that I’d suggest making a topic on a calculator forum like Cemetech.net or tiplanet.org since there are many people with more knowledge on that than I have.

Sadly, even if you got a different color, a body swap isn't easy. There's heat melted and glued parts that are difficult if not impossible to put back. Your best bet is to try and glue it back together, or try and use the warranty to get a new calculator. :/

@evankaba Well the goal is to buy a cheap, broken calculator not a brand new one. Unfortunately it’s quite difficult to find a broken TI 84 Plus CE. It’s also very difficult to find replacement parts since TI sources many parts directly from manufacturers. Could you share what’s wrong with your calculator and which part you need? I might be able to help you out.

@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!

@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?

Are you sure it was the 83 Plus you transferred the internals to or was it the 84 Plus? The 84 Plus uses the same shell design as the 89 and I've never heard of fitting the 89’s internals into an 83 Plus! That's not saying it's impossible though, cool story!

I think you should add the phrase “JBL Spot” somewhere in this guide. Although I searched the web and iFixit, this guide didn’t come up because I was searching for JBL spot rather than JBL spyro.
