    Hi! Write your Model No. of the Laptop.
    First search the schematics of the Motherboard (MOBO) of your Laptop with the code number of (MOBO), usually found under the sheet of protection under the Ram socket or other area on superface of Mobo, frome the schematics and after you identific the IC Model, type, Function. Search the Datasheet of your IC, look for model, type(Function), how many Pins and configuratione connectionand. If you not found the same IC, now you can searche anather IC with all these Informations.

            You must check from the schematics about pin 18. if it is N/C you can safely use TPS51125.

              Thanks. Btw, it's dell inspiron N4030... Do you have schematics? I can't find rt8205b on my junk boards.... And pin18 somewhat is in use because it has a resistance reading when Chip is removed....

                Sorry, i've measured pin24. At pin18 there's a small caps connected and no resistance reading with respect to ground....

                          Dell G3 17 3779 - no display after mobo replacement
                          by mrsith
                          Hi guys,

                          I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.

                          Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,...

                          Unknown transformer : how to find a good replacement part ?
                          by the_rem
                          Hello guys,

                          I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

                          I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

                          PS4 controller left stick potentiometer replacement issue
                          by ezenia
                          Hello,

                          Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

                          So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

                          I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

                          by boosti45
                          i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...

                          klipsch kda-500 amplifier suitable power supply capacitor replacement ?
                          by r2digital
                          I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...
