Initially I thought it might be the OS serial number so I installed win 7 and activated,but I could see that again.

The laptop boots with the Serial Number Not Found message. The BIOS displays all zeroes in the information section. I have a clear label with serial number, product number, windows 7 activation key. From my research, it appears that some recent HP utility has wiped the serial number.
When I power it up, a black screen comes on that shows 'serial number not found' and it also says that my copy of Windows 7 Home Basic is not genuine – but my computer came with Windows 7 Home Premium.
In BIOS, my serial number is not shown either and I did pull out the little battery to reset it which allowed me to bypass the suddenly new locked BIOS that needed a password to enter.
I'm sure this is a masterpiece created by my 6 or 9 yr old child while trying to play on my laptop.
Can I fix these two problems?

Judging by the comments (blanked BIOS serial, etc) it looks like your computer has suffered a BIOS damage, perhaps because someone tried and failed a BIOS update (but usually the computer doesn't start at all) or by accident.
You see, on modern computers these information are still flashed somewhere in the motherboard ROM, so could be subject to overwriting.
If you can't use recovery DVD to reinstall the software (I expect the same result but I would give it a try) you should call HP and report this as a hardware failure.

Hp Serial Number
I have worked on a computer recently that this happened to.
I was able to fix the missing information in the motherboard ROM. Here's the forum post that helped me: http://forums.mydigitallife.info/threads/2231-DOS-BIOS-Reflash-DMI-Edit-on-HP-DV6000-9000-2000-amp-CPQ-V3000-6000.
I started researching why this has happened. your answer made better sense then what i could come up with.
As for the 'Windows is not genuine' issue what i have discovered that with no serial number or any other info in the ROM then Windows itself will not activate for you. On an HP 71 at least you must fix this first.
Once i entered in the serial number pcid etc. Windows activated itself.
