    Re: Acer 5742G dead after stress test

    Ok sounds doable...

    So I remove the bios and reprogram it using an external writer?

    Any tip on a good eeprom(?) writer?
    And where to find downloadable bios'es?

    Agree with Unique, do flash bios and ec first, than we'll see. I had three these laptops with the same problem and flashing helped.

    Don't think so. A short on the CPU VRM would still have the board light up the battery charging LED.

    Sounds like a faulty VRM or CPU.

    You need to take the laptop apart and use a BIOS programmer to flash it.

    Acer 5742G dead after stress test

    Looking for advice..

    Acer Aspire 5742G started to power-off due to overheating.
    Now it wont start at all, external power or batt.
    It shows no lights when connecting power (no sign of battery charging).

    I guess something has fried around the power-circuit...

    The last thing I was doing was a small stress-test...

    (The external power is working with another Acer)

    Mb is "NEW 71 LA-5893P"

    Someone that can lead me on the way trying to find whats got fried?

    Acer Veriton N4670GT Dead
    by bripoll
    Hello, I have an Acer veriton n4670GT that, due to a fall to the ground, only started if I did a BIOS reset.
    The power button ar ok, and when power off windows, then if press power button, this power on, but goes to boot loop, like press power button forever

    It crossed my mind to try a BIOS update and when I finished it turned off and no longer starts in any way.
    I have a flash programmer, but the file you download from the Acer website has a .CAP extension, it is not a .BIN

    I have programmed it, but it still won't start, it is dead
    Before programming...
