CoolBreeze,
Laptop RTC and keyboard tests can sometimes be problematic. Laptops are very specialized hardware.
Did you use the HP bootable diagnostics to test this system? Please go to the HP website and download the PCDR bootable diagnostics from there and run them. Let me know the results.
The keyboard error is most likely the laptop keyboard not doing something a standard PS2 emulated keyboard should do, which in itself is not a problem on a laptop if it is designed that way. The same with the RTC test.
