    Hi All,

    Thank you for your time in reading. I've spent hours and hours this morning trying to resolve this myself but I'm getting nowhere.

    I turned on my Compaq (HP) Presario CQ61 this morning to be faced with a messaged telling me my Windows 7 software isn't genuine. I tried to activate online but it failed giving me an error message and asked me to contact HP. They won't help me unless I purchase extended warranty. I spoke with a representative for Microsoft activations and they have told me I need to contact HP as it's a hardware related fault.

    I've discovered that the serial number and product/part number is invalid in BIOS. Instead of it displaying my serial number and product number it shows only as zero's. When I power on the laptop, I'm displayed with a message at POST stating Invalid Serial Number.

    I've tried to flash the BIOS with the latest version although this hasn't helped. It flashed successfully but the numbers are still zero's.

    I believe the software used to edit these strings is known as DMI editors? They are all DOS programs though that I can't get to run within my 64 bit version of Windows 7 and I don't even know if I've downloaded the right one?

    Any support or advice would be much appreciated.

    Thanks again

    that will need to go to a HP/compaq repair center for that one ( or at least a local computer shop that is used to dealing with laptops in this situation)

    They are the only people that have the equpment to deal with that and it doesn't sound like a simple software problem

    however it might be as simple as the bios battery is flat and therefore the bios cannot read the serial numbers from the bios chip

    Warning: most laptop bios batteries are soldered in and any wrong or careless soldering can ( will ) render the laptop totallly useless
