    Philips Freevents puked on, not charging

    Hi everyone,

    New member with a problematic laptop

    History is the laptop was puked on by our baby daughter. It was immediately turned off, battery removed and placed upside down to get the boke out.

    I then pulled the laptop to bits (had done this a few times already) and any surplus boke removed. None seemed to be on the mobo or other electronics. Keyboard took the brunt of it.

    Anyhoo, once dried all was reassembled, connected to power and booted successfully.

    I then put it away

    Now, a few weeks later I booted it and noted that the battery was showing "plugged in, not charging". Not sure if this was shown when reassembled initially. I have double and triple checked the assembly and I believe it's fine. It's been like this for a year now but I'd like it sorted if possible.

    Can anyone advise how I test the health if the battery? I can buy a new one but don't want to commit 80 quid till I am more sure it fixes this issue, seems like a big coincidence the battery dies after being boked on, no?

    The power supply is fine, internal cabling from this to the mobo seems fine, battery pins look fine and corrosion free, no visible damage (liquid or other) to the mobo either. Fresh install of windows didn't help.

    I just run it on mains now but leave the battery in, makes no difference if it's in or out obviously

    As soon as the power is pulled the laptop dies

    The battery capacity always stays at 0%.....never charges

    It was never awesome, maybe used to get 2 hours but after the boke/unused period, it just died......that made me think more that damage was done but I can't be sure.

    Id love to know how to check for sure if it was the laptop or battery but we all no its not a simple 2 pin setup like a regular battery




    I did some basic tests as below (see pic attached):

    Ok.

    All measurements taken assuming that pin 1 is negative (black on my multimeter)

    Battery out / Power connected / Computer off
    1 to:
    2 - 4.55v
    3 - 0v
    4 - 0v
    5 - 2.65v
    6 - 2.65v
    7 - 0v

    Battery in / Power connected / Computer off
    1 to:
    2 - 2.0v
    3 - 0v
    4 - 0v
    5 - 12.65v
    6 - 12.65v
    7 - 0v

    Battery in / Power connected / Computer on
    1 to:
    2 - 2.0v
    3 - 3.3v
    4 - 3.3v
    5 - 12.65v
    6 - 12.65v
    7 - 0v

    Not sure if that helps but the mobo obviously changes the voltages to pins 5 and 6 once the battery is connected.

    Also, once booted, pins 3 and 4 come to life

    Pin 7 does nothing though.

    And obviously, i know nothing about electronics but I am not afraid to have a go. Just ask the gearbox in my old car

    Any and all advice appreciated guys.


    Oh, and i only broke the wee partiton between pins 2 and 3 on the battery today being clumsy. Problem was present before that.



    Thanks
    Andy

    I spy a fuse (F3) below the connector. Checked that (or others in that area) yet?

      Hi buddy,

      No, I havent checked anything.

      As i say, I am an electronics......well, nothing.....lol......i didnt even know that was a fuse....but i am game for a try.

      All i have at my disposal is a cheap multimeter, its done me so far.

      Can you offer some guidance as to how and what to check?

      The ohms settings on my meter only cover 2000k, 200k, 20k, 2000 and 200.

      Am i talking utter gibberish?

      lol

      Regards
      Andy

        ok, set my multi to 200 (ohms?) and that particular component showed 00.8

        Not sure what I am doing but hey-ho.....lets go

          I did a continuity test between pin 1 and 7 and it beeped so i think they are one in the same.

            £80 for a battery!? A new battery should be <= £20 on ebay!

                Personally I've never had a problem.. Can't speak for everyone, though. All the £20 batterys I buy come with three years warranty.

                  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...

                  ASUS X571 no power : battery issue?
                  by mkdj
                  Hello everyone,

                  Mark and model: ASUS X571
                  Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.

                  Tests already made:
                  - Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
                  - I have removed...

                  Vostro 3400 (LA-K033P) won't charge battery, everything else ok
                  by techfreak9356
                  I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

                  The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
                  configurable for operating as either a Hybrid Power Boost (HPB)
                  charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
                  4-cell batteries. Both configurations allow the battery to work with
                  the adapter together to supply the system load when it exceeds
                  the adapter capability, referred to as system Turbo mode. HPB

                  HP ELITE X2 1013 G3 weird battery issue
                  by huzo
                  Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...
