Today I was doing a mobo swap from one X60T lower assembly I got here in the forum to another X60T. I had a small surprise when trying to install the pen assembly (I don't know if this is the official name) for the digitizer. The basecovers were slightly different
The donor lower case looks like this (FRU 42W2547):
... and when trying to install this pen assembly:
... I then realize that the receiving base cover looks like this:
So there's no way to install the pen assembly due to the extra notch on the left of the cover. Note that there are three notches on the first picture but four on the third. Now the digitizer will get inside the tablet, but it's tricky to get it out. Is there any reason why Lenovo has two different bases? Or maybe my X60T has a non original basecover? Or there is a different FRU for the pen assembly...?
Unfortunately when I realized this issue I wasn't willing to remove all the components again to check the FRU number of my X60T
Any help would be appreciated! Thanks a lot in advance!!
