    Is this Lenovo Super I/O chip dead?

    The laptop stopped working after the charging cable was accidentally dragged across the room! This resulted in the charging port getting torn apart and short circuiting.
    I got a new charging port but this did not fix the issue and as I was investigating the board I discovered the marks on the Super I/O chip. I wiped off what seemed to be a powdery substance that was exactly above where the marks are around the first 'o' in the lenovo logo on the chip
    My question is this do I need to get a new SIO chip and try replacing it?

      Most likely yes, and you need to probably reprogram it also.

              Such clinical cases wen fire comes out of chips are often fatal, you may have dead Intel combined CPU in addition. Data code on SIO tells that is middle 2014, guess this is something based on Hasswel... No board name - no points to diagnostics.

                  Terribly sorry!
                  It's a Lenovo G50-45 Model: 80E3
                  The laptop is fully dead, no power, no charging. I took a multimeter and had a go at diagnosing the motherboard when I saw the Controller IC as you see it. And after furious googling I couldn't find a picture of a chip with similar damage, so I though I'd show the IC someone that might know what they are looking at :-)

                      Check resistance to gnd on LE1. If low, remove the EC and repeat measurement. On ebay they sell it already programmed also.

                              It is super dead. I have four Lenovo motherboards like that. I want to order for a replacement.

                                  Hi, Wanna ask, can i use any Lenovo IT8586E Super I/O chip (already programmed) on any Lenovo Motherboard using that same type of Super I/O or the Programmed Super I/O Chip is Model specific?

                                  For example, I have Two (2) Lenovo G40-30, One (1) Lenovo G50-45 and One (1) Lenovo Ideapad 11e. They are all using that particular model of Super I/O. So, the programs have to be according to their model or not necessarily?

                                              Hi all,

                                              As the title suggests, how can I be sure that my EC chip is really dead?

                                              I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

                                              Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

                                              Hi

                                              I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
                                              The SPI chip is an Winbond 25Q256JWEQ model (1V8).
                                              The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
                                              The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

                                              I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

                                              by geotox
                                              Hi, after a short circuit during power cord plug-in the IT8226E-192 chip on my Lenovo Legion Y540-17IRH 81Q4 died. I'm trying to order a replacement for it. There are some similar chips available online, but they are not 1-to-1 identical to my chip. For example, I see there's a 1921BXA chip available for sale, while mine is 1932BXA. Do you guys know if there's any compatibility table available which I can use to see what chips are compatible? Should I just order a similar chip and try it? Will I need to program the chip before installing, or will the laptop do it for me?

                                              Thanks...

                                              I have a Lenovo ideapad 330S - 14IKB laptop.

                                              Hi guys
                                              i got a dead t440s the bios chip is "W25Q128BV"
                                              testing with multimeter all good as i think
                                              but i get a 0.052 on the 1th PIN of the chip

                                              if i remove the bios i get the same 0.052 with the adapter removed
                                              and 0.024 when i plug the adapter.

                                              so what do you think?
