    at first when i checked the PPBUS line with diode mode it beeped really long and it started from 1.000 and went down to 0.146 and after that it did stop the beeping.

      Same voltage at J7050?
      If yes, probably bad battery,
      Check R7050 too...

        As there is a Schottky diode involved, 0.146 reading is correct at F7140...

          I already checked the R7050. It is 10K Ohms and there was 0.1 volts. When i checked the R7050 with diode mode it was 2.116 from both sides. And J7050 is good. I have checked if there was under it corrosion but there was not.

            Jesus Christ how hard can this be? IS THERE 12V ON F7140 WITH THE BATTERY PLUGGED IN, NO CHARGER CONNECTED OF COURSE? If yes then there should be 12V getting to R7005 or there is a fucked trace.

              dukefawks You are getting angry quite fast. First of all i have already answered your question. There is no need for getting angry. Check the page two for the answer.... if your not up to it. I will copy it for you.

              No i have not. Now i measured it.

              F7140 PIN 1 = 0.5 volts and increases slowly. Pin 2 the same.

              F7140 beebs from boths side and its not blown.

              Checked with diode mode the PPBUS line and it was 0.146.

              AND THERE IS NO CHARGER PLUGGED: ONLY BATTERY.

                  Buy a working battery.

                    We are back to my advice from page 2. buy a working battery.

                    The only reason I don't divulge where I buy batteries is they can barely supply my one store, much less 1000s of other people. Half the time I order they are out of stock.

                      The battery was shit. Bought a new battery from here, works great and as good as the original battery. Thanks everyone!
