Issue Details

  • My PXI or PXIe controller's clock repeatedly loses its time. Why is this happening?
  • Why does my Windows time reset to 12:00 AM every time I boot my PXI controller?

Solution

This issue may be as as a result of the BIOS software or possibly the need to replace the CMOS battery. Therefore, there are two possible solutions to this issue.
