A laptop, ehh?
The easiest thing to try is to boot into the BIOS and select "Optimized Defaults". Save and exit (Prolly F10). See if that does what you need.
The next and much more difficult option is to remove as much of the case as is needed to access the CMOS battery. Remove the battery, wait about 5 min, and reinstall. Put the case back together. Boot into BIOS and again, Load Optimized Defaults. Save and exit. Boot into the OS and see if your problem has been solved.
