    Ti Nspire CX CAS

    Hi all!
    I have a Ti Nspire CX CAS graphing calculator. I'm not sure why but for some reason it died while charging. It went completely black and won't turn on anymore.

    I tried to charge it again and noticed this chip (see attached image) getting really hot in seconds. I think that that chip is fried and should be replaced, but I don't have any idea what it is. Can you help me figure out what chip is it? I think that it has something to do with power delivery. The chip gets hot if the battery is full also, but not when it's almost empty. In case it helps this calculator uses a 3.7V battery and it's charged via USB.

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      A: If you can`t read from it how do you expect to write to it ?.

      Q: Why is my bios chip unreadable ?.

      A: The programmer is faulty or has a worn or broken zif socket.

      The USB cable is frayed,connector pins worn or some other physical damage.

      Asus Chromebox CN62 - wrong chip put on BIOS reader
      by BMCappelletti
      Long story short:
      - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
      - gave the computer to his son a couple years later
      - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
      - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
      (seems like the story was not that short)

      He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

      Acer e15-e5-576g-5762 bricked. Bios chip won't interface in AsProgrammer.
      by inck243
      Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.

      The BIOS...
