I just recieved the bluetooth module from hellowifi and installed it in my s10.
Here are the instructions (I performed this on my s10 with vista home premium, but the process is the same for XP)
1. Remove the battery from S10
2. Flip the laptop over and place it on its back on a soft surface that top surface does not get scrathed
3. Remove the four screws at the bottom (See picture)
4. Flip the laptop over to normal orientation and open it.
5. Now try to press the edges of the palmrest area to release the two notches and the top left and top right corners of the plam rest areas. There are two notches and once you release one the other should be easy. Work slowly and try not to break these notches. There is some flex to them, so i think you will be ok as long as you dont pull too hard.
6. Now lift the palm rest open, but do not pull it too far, There are two cable connecting this to the mainboard, you want to leave them connected.
7. Once open, you will notice the bluetooth cable socket on the bottom right corner and there should also be a place to install the module.
8. The cable that comes with the module has the same type of connectors on both end but they are wired differently. So you should pay attention to which connector goes to the mainboard.
9. My cable from hellowifi came with a black tag at one end and that is the end that should be plugged into the motherboard.
10. Once you connect the other end module you can place it the area where the module goes.
11. I used some double sided tape to hold the module in place, but you can also use a small scree if you have one handy (unlikely)
12. Now put the plam rest cover back on and press on the two top corners to latch it in place.
13. Now flip the laptop over and install the 4 screws
14. Now install the battery and power it up.
15. Your OS will detect the module and ask for driver, press cancel or any other prompt that lets you skip the step.
16. Download the bluetooth driver from lenovo's support site or You can also install Bluesoleil instead.

17. Make sure your wireless button is enabled state.
18. Install the software and follow onscreen instructions.
19. Module should now be enabled and the LED indicator in the front should turn purple and the system tray should show a bluetooth icon.
20. Restart the laptop to enable all the functionality.
21. Once restarted, login to the system.
22. Right click on the bluetooth icon in the system tray and click "Start using bluetooth" (This is on vista, please confirm if you have to do this on XP)
23. It will install several bluetooth services as shown in the picture below and yes, Stereo Audio (A2DP) is one of them.
Wireless button does seem to disable/enable both bluetooth and wifi. I wonder if there is a way to select which ones to disable.
