    use different bios version. .. take 1 ram stick out ( might be bad)

    or u have the "BGA needs reflow"]

    folder needs C capitalized and u have it in wrong place.
    (usbstick) \Hewlett-Packard\Bios\Current and Previous ( not current or previous)

    Try to the step you said but no result. i did not know what is "BGA needs reflow".

    Can anyone send me the right BIOS file and how it will recover my BIOS? i am using a USB flash disk from Transcend and capacity is 16GB.

    thanks.
