    Hello everybody,

    today I have cleaned one laptop fan. It was HP compaq CQ57-313sc model. It was working correctly, but cooling fan making some noice.

    Ive disassembled that, cleaned fan components, put a little oil for better rotating.

    After I turtned computer it wrote me fan error message and fan was not rotating. Then I tried reassembly again and I got same error. Tried it 3rd time and now I get only black screen without any error and power button is ON , caps lock blinking...

    What could happened ? Should I buy a new cooling fan with heatsink ? Or can it be processor/RAM/motherboard problem ?

    Can you help me please what to do ?

    Thank you very much.

    Read and follow the steps outlined... here. Confirm Flash/Beep code. Listen carefully for fan operation.
