    Re: BAUN - UVST - 0617,Can anybody Identify these Please?

    Hey R_J I need to re-check in a few hours, so I don't give you false information.

    I will attempt to draw out a basic schematic.

    I asked if you traced out the pins to see if this is the same ic, For example, pin 3 seems to connect to CON3, is this where the battery connects???

        Noppa - Would you happen to know what SOT it is please?

        I know it's cheap, and the moment I collected it, it wasn't worth the repair, but it's for a friend.

        I love problem solving

        Thanks again..

            The TP4054 is a sot23-5, just look at the datasheet, the XX4054 seems to be made by may companies with a slightly different part number

            After a closer look at the picture in post #10, I see CON3 is the battery connector, so this must be the correct ic.

                They are a distributer not a manufacturer. Just pick your favorite parts supplier and order one.

                    Hi R_J

                    You are correct, the CON3 is the internal Battery

                    I will look for a replacement, and see if I have any on old Laptops

                    Its been an uphill struggle ans Manufacturers and component suppliers really Wont or dont Help, so the folk sin this Group have really helped go in the right direction

                    Will Keep you updated

                    Stay Safe

                        Thankyou stj

                        I was starting to worry where to get one from.
                        I have started to use ebay, a couple of weeks ago.

                        Would you know of a trusted supplier, or shall I just use Aliexpress?

                        I was scammed already last week.

                        Stay Safe !!

                            change the shipping option to:

                            the default one - "Cainiao Super Economy" is slow as fuck and often loses packages!

                                        for 10 laptops i would jump a train to watford.

                                        reason i asked, a lot of people say London when they arent in london.
                                        i got stung once, bought a heavy item on ebay with the intention of collecting and then the fucking seller said he was on the border of kent - the coastal facing border!

                                          I got scammed 2 weeks ago

                                          I advertised a TV in the Buy/Sell section on Badcaps that has a good screen, and are hard to get hold of

                                          If I ever get anymore Laptops, you are free to pop over, I can give you my address.
