    No when I press start I get only the error message and then I can nothing more
    everything works now as the fan/hd/all lights.
    Only the symbol to indicate that the hd is working not fire
    Have the memory tested is also good the hd in another
    pc tested and that works too, but I think I need to put a new bios in it but how do
    I that?
    Hope someone can help me with this.
    Thanks for the effort.
    Regards Hans

    Most laptops have a design to prevent bios tampering (keeps security on even when people steal the laptop). I have had some that have no kind of reset available.

    You may have to buy a chip flasher and flash it from the outside if it's even accessible.
