    dell n5110 no charger detect

    Hi i have a dell n5110 laptop.
    it was dead as it was water damage.
    i cleaned all the corrosion and replace one of the p channel mosfet.
    its now working but charger is not detecting

    I had replaced the charger but same problem.
    also re soldered all the charger point.

    i had search the net but there is no schematic for power board

    (dq15dn15 crt board)

    What do you mean charger is not detecting???
    Does it work on battery only???
    Did you check charging circuit???

          I don't understand you...
          How could it start up when charger is not detected?
          You mean it works on battery only...
          If you're reading 2.8V on DC jack, you have a short on it, or short somewhere on charging circuit...

            Sorry mate...

            I'm a dumbass...
            Didn't read it properly...
            Did you try to measure DC jack on power board disconnected from mobo?

                Still need to clarify...

                -It works on charger (without battery connected-only charger)
                -It works on battery (without charger connected-only battery)
                -& it also works when plugged in battery & charger, but it's not charging the battery

                ???

                  Re: dell n5110 no charger detect

                  i have to ask because i have a universal charger that i use for all notebooks adn that one does not charge the dell battery`s only the original one with a good power like over 90W; mine its 135W
                  Just cook it! It's already broken.

                    Re: dell n5110 no charger detect

                    i had checked it.
                    there is 19.5v
                    and center pin sows nothing.

                    while connected to mobo it shows 2.8v

                            Could you measure voltages on all pins @ PU4002 & PQ4001???

                              the mid pin has to give voltage

                                    Yes, but he says it works on charger, without battery plugged in, so reckon it's getting 19V...

                                          Hello, everyone!!! Happy New Year to all!!!

                                          When I turn on the laptop, the warning appears: You have attached an undersized 0W adapter and blah, blah, blah... The bios says that the adapter is not connected and the battery status is excellent.

                                          This laptop has all the voltages at the input, and the charger IC is also normal. There is 3.3V at the PS_ID and I have already tested it with another adapter, also original. The adapter detector also seems to work normally. I am suspecting the SIO. What do you think?

                                          On my portable oscilloscope there is a PS_ID signal....

                                          Hello,

                                          Dell Latitude 5420 P137G
                                          Board: LA-K491P REV A01

                                          I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

                                          Board seems to have no shorts, all power rails are fine and show high resistance.

                                          When charger is plugged in, voltage is present in 3.3V rail but absent in others....

                                          by Johndill
                                          Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
                                          There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
                                          I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.

                                          Here are the tested scenarios:

                                          1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.

                                          2. With the laptop off, plug in charger (LED says on) & the front charging...

                                          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                                          by Bowline
                                          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                                          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                                          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                                          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                                          I have tried multiple different Dell power adapters. My Dell...

                                          Hello, I received this laptop with the following condition: When I turn it on, it shows the ALIENWARE light and the Alien button lights up, then it does not show an image and it restarts constantly, as the customer had already informed me that the battery was dead, I connected an original charger that I had it for testing, the machine turned on normally and I was able to enter Windows without problems, after a while of testing I noticed that it is very slow (like a Cyrix 425...), and after performing a CPU test the frequency is
                                          below normal, as if it were operating in an extreme energy...
