Missing COM Ports in Device Manager RRS feed

  • Question

  • The first indication was lost of modem functionality. After checking, I found all COM and local ports were missing in Device Manager. Need to know how to restore these ports? This is a Acer laptop running Windows XP. The BIOS settings are very limited with no options to view either ports or interrupts. I have tried unsuccessfully to reinstall the modem (intergrated on the mother board) including uninstalling in Safe Mode, rebooting and reinstalling in regular Windows mode. Still no ports are shown in Device Manger. How do I restore these ports?
