Hello,
Thank you for contacting National Instruments. There are no VIs that specifically return available power, but you can easily access the internal PocketPC or Palm DLLs to return the battery power information. Please take a look at the attached VIs. We're still working on these, so let me know how they work for you and whether you find any problems. Please also check out the attached "readme" for more information about each of the examples.
If you have not worked with external code via the PDA, you might also want to check out this great KnowledgeBase:
KnowledgeBase 33BFP5QS: How To Call External Code in LabVIEW PDA for Palm OS I hope this helps! Let me know if there is anything else I can do for you. Have a great day!
