      Haven't killed a chip for a good while now, it's been over 1 year... Burned some nVidias a couple weeks ago but that was experimenting, they were bad chips i had collected, and they were headed for the bin anyway. One of them made the grade and currently runs fine in a Dell Vostro 1510, but that's just for testing, and it's in one of my own laptops. I have a new chip on the way for that laptop, so when it dies again, no big deal. If it works for a good while, i'll let you know what i did to it.

      But yes some boards are crap and bend. If you're paying attention and spot it when it starts bending, you can get it back in shape, but it requires some creativity. Blue boards (mostly Compal ones) seem to me like they're the worst offenders.

        I just removed this chip from Quanta NE8 Rev C (Sony VPCEF) suspecting it's bad.
        I have 0V reading on an only big cap on the chip. All other power rails are fine. Those schematics out there are not match but readable for guessing.
        I have resistance of that cap is around 13 ohms (chip removed). I would like to ask is it normal or dead.
        Thank you for any input.

          It's normal. If you read 0 volts with power applied and 0 ohms with power unplugged, with the chip fitted to the board, without it shutting down in any way when you power it on, this is normal. Some manufacturers like to connect the unused sections of the chip to ground, thus throwing you off when you're doing measurements. You'll find this is true if you look carefully at some schematics.

          If the chip doesn't have any dead shorts (under 4 ohms or so) when removed from the board, it is likely good. Your board has a different issue in this case. I used to say "under 10 ohms" would be considered a short, but i've since seen some ATi GPUs, both old and new (as in generation), reading ~5 ohms across some of the ceramic caps on the top, and they were in perfect working order.

                There is a simple answer: You got sold fake chips.

                    i bought a 2014 216-0674026 and work very well.

                    i agree with the unique, they could be fake. what is the shop you bought from ? and how much you paid for it ?

                    2014 should costs around 30 dollar ship included.

                        Managed to move a few 0402 ceramic caps when lifting the chip and cleaning the board, had to place and solder them back. But other than that, reballing went smoothly with no issues.

                        You can also notice the shit quality of the board's solder mask, which scraped off in a few places.

                                        The international market price is about USD25 to 27 for both 2001 and 4026.
                                        I had seen the inv from AMD to my supplier which they buy in lots of 1 thousand.

                                        So anything below this price just take your own precautions.

                                        YES, Chinese can remark the chip. What ever date code also possible.

                                        Just buy a sample from those selling originals, and you can see the difference physically;
                                        The greenish colour
                                        Solder ball colour
                                        Defects in body (chip edges)

                                        We are the ones who fix those boards, hence our reputation is at stake.

                                        Go for Alibaba suppliers, Taobao isn't a good place to source for BGA.
                                        I never had a failed BGA for almost 2 years already, approx 500 pieces all usable. Yes, I do pay almost USD30 a piece for those, at least I am getting what I asked for, new originals. If you can't get anybody to sell you a few pieces, let me know, I can help ship it direct from China to your location for a small handling fee, I have my own shipping warehouse in China (Dongguan), actually just to ship back to my own country in Malaysia for my business here.

                                        DC 2014 for 2001 and 4026, so far haven't encounter needed a bios update or mod to get it to run on those old boards.
                                        Mainly repair laptops, sometimes LCD/LED monitors. Also accepts changing/reballing/reflow BGA job request.

                                          Very true words here above. I would be interested in a few pieces of G86-771, G86-731 and G86-631 and possibly a few others, but that would be after the holidays so no rush.

                                            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...

                                            Hello, anyone here have updated ezp2023+ chip database in .dat file format.

                                            I need to add w25q256jveq chip but I do not know what data should I type.

                                            I'm using the ezp chip dabase editor posted from here https://www.badcaps.net/forum/troubl...ro-programmers

                                            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...

                                            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...

                                            Lenovo laptop does not turn on, what does this number mean in a BIOS chip?

                                            Hello, first of all, excuse me, I am using the translator, English is not my native language.

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



                                            The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...
