I needed a new MB for the X41, and this eBay item
worked out, but there are a couple of notes I would like to record for others considering the same FRU (42T0013). If the eBay link gets stale, just search for 42T0013, as these seem to be in plentiful supply. The transaction with seller IMS was A-OK. Notes:
1. This FRU has 256 MB of system memory, not 512 like the dead one that was in it. I'll probably want to put a 2GB PC2-5300 stick in it, as these are plentiful and cheap now. The 5300s are actually cheaper than the 4200s in my area.
2. This FRU does not support the fingerprint sensor. There is no socket for the fingerprint reader cable. Not important to me, but the machine has one that is now non-functional.
Not an issue, but there is a mystery socket at the very edge of the board next to the top-side RAM chips. The old one didn't have this. Did any X41s have a separate security chip not soldered on? How do I tell if the current one has a security chip in it?Edit:
The presence of the mystery socket confirms that this is an X41T MB. In the X41T HMM, there is clearly a second cable coming out of the LCD module that goes there. I still don't know if Lenovo intended this MB for both X41 and X41T.
