    Hello,

    I have here a burned chip on Sony laptop motherboard Model PCG-8131M with
    marking "AE" on it. Please can anybody tell me what it is and what is the
    actual chip number. May be anybody can sell I would pay for it or offer a
    service

    It has 5 pins and looks like this (actually there are three of them)

    Thanks

    Update: the model is (from the lcd bezel) VGN-AW11M

    Looks like it could be some sort of SMD voltage regulator, though there are many devices that could be in that form factor.

    Yes you are probably right. But the difficult part is I can't find any device with that code ...

    Nice reply. All he need to do is know this PNP silicon transistor's settings and buy and install the closest possible in characteristics transistor :).

    Unlikely to be a BCX52:

    - that's in SOT89 package but the component is in a SOT25 or SOT23-5 package
    - the package has 5 pins which means it is unlikely to be a simple transistor
    - the combination of three on the board next to a power plane makes me think it could be a voltage regulator; exactly which one though could be a problem to determine.

    hello all

    it has been repaired by cocotec dot co dot uk in Birmingham. Guy from there replaced this chip with markings CE and three dashes. They also replaced i\o chip. All together was 120 pounds. Yes expensive but this was worth it as the laptop works again now.
    When I got there I though what a dodgy place to leave my laptop. But no worries they know what they are doing. They repairing motherboards.

    WPCE775LA0DG and that 5 pin chip with markings AE three dashes replaced with a chip CE three dashes that's all I know.
