    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...

    A1312 (27” iMac 2009-2011) A1407 (Thunderbolt Display) A1316 (Cinema Display) Display Black Screen Repair

    Problem

    This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

    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...
