Serial number not found
I'm Bojan and I have HP DV5 and it doesn't start up.
For some time, on boot up my laptop, I've received message Serial Number Not Found and Press Enter to continue, after that Windows boot up. But few days ago I've got black screen and message Serial Number Not Found and that's it.
I cannot enter BIOS or anything.
I tested HDD and it's OK.
I tested RAM and it's OK.
When I disconnect HDD I managed to access BIOS and in Info section Serial number missing, CPID are zeros and some other data are missing or zeros.
It seems that I need to enter eeprom and try to fill missing data. I have all necessary data except CPID. It should be sticker somewhere on laptop but I cannot find it!
Do you have any suggestion or advice?
