Note directly for the 1170 but it looks like it may be a motherboard problem:

Well HP can not tell you about a CMOS Battery because there isn't one
With this M'Board if it is the same one used in the NX98008. This M'Board uses a Smart Socket as a Power Source for the BIOS Chip to power the RTC.

What you may need to do is leave the NB plugged into the Mains Adapter to recharge it for about 36 Hours. If it's still not working after that you need a New M'Board for this NB. Of course if the Main NB Battery is dead and still fitted this could be causing the Smart Socket not to get charged.
