    elitebook 8440p

    this laptop was blinking (caps and num lock) 5 times but it displays the hp logo screen with " press esc" but nothing else, even when i press esc it will does nothing....
    i tried to remove HDD but the same problem....
    i tried to do Bios recovery by pressing windows+b with no success...even the system did not read the usb at all to recover...
    i shut it off then on but now i have no screen at all with 3X blinking caps and num locks
    i thought it is Ram, i changed it but still the same
    i removed cmos battery, it works again but after restart or shutdown, it again has no display

        To me also it seems like a corrupt bios. maybe, the bios image you flashed is not proper.
