The Service Manual has detailed instructions on how to replace the battery.   Note that it does require removing the system board -- but it also has instructions for doing that         Just click on the hyper-links to get to each of the appropriate steps).

Here is a link to the Dell service manual documentation for the 1750 on how to replace the CMOS battery.

http://support.dell.com/support/edocs/systems/ins1750/en/sm/coinbatt.htm#wp1179886

Note that where Dell simply says "Follow the procedures from step 2 to step 17 in Removing the System Board," there are 12 different procedures in themselves to be done:

Removing the System Board

2. Remove the battery (see Removing the Battery).

3. Remove the module cover (see Removing the Module Cover).

4. Remove the memory module(s) (see Removing the Memory Module(s)).

5. Remove the hard drive (see Removing the Hard Drive).

6. Remove the optical drive (see Removing the Optical Drive).

7. Remove the Mini-Card (see Removing the Mini-Card).

8. Remove the center control cover (see Removing the Center Control Cover).

9. Remove the keyboard (see Removing the Keyboard).

10. Remove the Bluetooth card (see Removing the Bluetooth Card).

11. Remove the palm rest (see Removing the Palm Rest).

12. Remove the ExpressCard reader board (see Removing the ExpressCard Reader Board).

13. Remove the battery extension board (see Removing the Battery Extension Board).

14. Disconnect the speaker cables and the USB module cable from the respective system board connectors.

Advice:  As each part is removed, from the unit, put it in an envelope and label it.  My experience is that it's impossible to remember where each of those 68 different screws came from after disassembly is complte.

Sorry for the duplication, garycase.  I wasn't in a hurry and it took me half an hour to complete the posting.
