You are not going to find a CMOS battery or jumpers. That is good advice for a desktop computer but modern laptops with an internal battery use that battery as the RTC/CMOS battery so if you want to "reset" it remove the battery from its connection on the motherboard, let the computer sit for 30-60 minutes then plug it back up and try again. The chances this will work are very small but not zero. 

See p. 29 of the Manual here:

Are you still under warranty? This is not a very old laptop. If you are then best not to open it and make a warranty claim.

Go into BIOS and reset to default settings. When you remove the RTC clock power it sometimes makes weird settings in the BIOS. Check system time, too. It may be off. 

You might want to accept as solution as this was pretty good free technical support and others might want to see it.
