Infra red port is blocked when my LifeBook S7010 is docked on the port replicator. Can I still use my infra-red port?

I want to disable Wireless LAN and Bluetooth device separately.

I bought a new S6130b in Singapore and it came with Intel Wireless 2100 3b and Bluetooth as standard. I would like to upgrade to 802.11g Mini PCI Card. Is there a way to do this?

How do I activate the IR port on my S6130 laptop. I would like to update my handphone software via the IR port.

Do you have a patch that turns off the "num" key of my LifeBook S6120 keyboard because I am using an external "num" keypad.

My LifeBook S-4540 is installed with 128MB RAM. Does this model support the 256M RAM module? If so, is there any restriction with regards to the RAM module (e.g. PC-100 or PC-133)?

My LifeBook S-4562 does not have the Ethernet adapter, but my university requires us to use this Internet card when we access the Internet. Please let me know if my laptop has such hardware support. I have tried downloading the drive from your web, but to no avail.

The specification for 'Mobile Slot' states that it is a 'Combo Drive/DVD Drive'. Does that mean I should select one of them?
