My T400 (well both of them) came without the cellular data/GPS PCIe module, so I got the Ericsson one, that is one of two types that could have come with it.
It’s "Universal Ericsson F3507G HSDPA WWAN MINI PCI-E+GPS” as described on eBay.
Given that I’m not interested in the cellular data part, is there anything else need doing other than install the module, and it’s drivers?
Then I assume you get an extra COM port with NMEA spitting out of it?
The best way to look for the correct module is to look in the HMM for the FRU numbers and search by those.
Do both of these laptops have the antenna leads for the cellular module? I think its possible that some thinkpads were shipped without them. You may not need the antenna just for GPS, but I really don't know.
Not having used one of these modules, but general cellular stuff, you may need to throw an old sim card in the laptop to trick it into working, it just won't find a network. Newer electronics are smarter and realized you don't need a sim card for everything.
Yes they still have the SIM card reader and both antennas.
If the module isn’t installed, both plugs are covered with some heat shrink and tucked near the empty slot.
Maybe I can get a Lenovo one from a fellow who wrecked a T400 (who has supplied some other bits for me).
For an x64-compatible system
For an x86-compatible system
Works for the R400 too, if I am not mistaken. Do be aware that the files have 2 BIOS files, since the other BIOS (7VET94WW) file was meant for a T400/R400 that does not have the IEEE1394a port or the FireWire 400 port.
I wouldn’t want that to go away, as it’s built in and neat, and I’d hate a usb one sticking out of the laptop if it's unnecessarily.
Interestingly one of the T400 has a camera, and one doesn’t. That requires a different moulded monitor case part.
That’s pretty weird for the same model laptop. Maybe this has been mentioned 100 times already, and I haven’t searched about it or anything.
What am I trying to say is that if you do wish to use the WWAN card that is not in the whitelist in the T400's stock BIOS, you should use an appropriate BIOS file that I have given in the 2 links found in my previous reply. The x86 link is for Windows OSes that are 32-bit, and the x64 link is for Windows OSes that are 64-bit. Pick one of those links that fits your current Windows OS installation.
In either x86 or x64 zip archives, there will be two files that will be inside the zip archive. One of BIOS files is what you should be using, while the other BIOS file should not be used. In this case, is your T400 equipped with the FireWire port? If it is, extract the folder that starts with 7U. If it is not, extract the folder that starts with 7V.
Then, follow the instructions provided in the readme that should be in the zip archive. This should be all you need to remove that pesky WWAN whitelist, and that would finally allow your Ericsson card to work in your T400.
