    Fried Toshiba Satellite U500 Motherboard

    Toshiba Satellite U500 Motherboard H000023260




    What I got here is a fried motherboard, I'm trying to figure out the missing components and their values. Having it crossed reference from other mobo pics from sellers, it seems that there are two capacitors missing and one resistor between the mosfets, also trying to know the proper pcd layout from the burnt part. I have already removed the two mosfets but I'm having hard time reading on their markings.

    Hoping that someone will tell me what their values are, and if there are still missing parts. If someone will kindly be able to post a good pictorial of their own board, that will be a big help on this project. Thanks

    Little history, I was told that the laptop was charged overnight, can't boot in the morning, only flashing leds. The fan can't run... It looks like that the unit was already checked by a technician but i can't confirm if the capacitors and resistor was removed or blown off.

    Not sure if this is a common issue for the U series, I have heard about other u series having the same problem, with charging circuits but not as bad as what I have now.

    By the way, I bought this laptop as defective and hardly hoping that I could get this running. Any help will be very much appreciated.

    the hole in the board makes this a goner!at least it looks like a hole at the battery connector.

      have plans in rebuilding the bridge. just need to sacrifice the battery connector when I have finalized the components. If only I could get a good picture on how this thing looks like. The pics from seller's site have this battery connection cover so I'm still guessing. It's a hole indeed, from which a golf ball wouldn't fit...hehehe...

          unless you can also fix the inner layers of the burned area you are done.
          look for another board or a unit with a busted screen.

            thanks for the advice. how bad do you think this is? will I have a lower chance of having it fixed? this kind of board doesn't seem to be common in our country, since the unit have arabic characters on top. Is this a common issue with the U series or I just didn't get lucky.
            The board cost at around 200Usd over the net, not sure if it reach me if ever i did purchased one due to tax issues.

              Tbh, that one looks completely ruined to me. Looks like something shorted at the battery connector?

              I'd just replace the board.

                My problem on this board is that the voltage goes crazy when puttiing the battery on. It works perfectly without the battery on. Blown R020 already replaced. Works perfectly on DC, but it cannot operate while on battery.

                Any ideas?

                By the way, Bochi, soldering the missing parts will not solve your problem here
