I need to disable the IR receiver device on my Fujitsu Amilo xi3650 laptop. Its running Windows 7 Pro. Its picking up IR signals intended for a separate HTPC running Windows 7 HP.

In device manager I've tried to disable the Microsoft eHome IR Transceiver device, however I guess its been marked as essential hardware as the Disable button is greyed out and unavailable.

Uninstalling the IR transceiver device driver only works till I reboot then it automatically re-installs.

I had a look in the bios but didn't see an obvious way to disable the hardware from there.

Is there a way (short of sticking some tape over the sensor) of turning the receiver off permanently?

I don't want to stop all hardware automatically installing on my machine just to get round this (I've seen this as an option when googling).

why not unplug the IR, or is it permanently attached? – KronoS Aug 16 '11 at 18:07
    
Its in a laptop, I think its soldered on one of the PCBs – Jon Egerton Aug 16 '11 at 19:32
  1. Click Start, right-click My Computer, and then click Properties.
  2. On the Hardware tab, click Device Manager.
  3. Expand Human Interface Devices.
  4. Double-click Microsoft eHome Infrared Transceiver.
  5. On the Driver tab, click Uninstall, and then click OK.

Already done that - just reinstalls on reboot. – Jon Egerton Aug 16 '11 at 17:44
    
BIOS. Advanced tab - look for infa red, or Bluetooth... – wizlog Aug 16 '11 at 19:26
    
As stated, I had checked that already, but I rechecked anyway and there are no options. (Its actually the most simplistic BIOS I've seen) – Jon Egerton Aug 16 '11 at 21:06
    
Is there something in the control panel settings under Turn Windows Features On or Off? – wizlog Aug 16 '11 at 23:39

I've taken the subtle step of simply covering the IR receiver with a (neatly trimmed) piece of electric tape.

There really ought to be a better way of going about it than this!
