    Just curious as to whether anyone has attempted this? I'd like the capability to upgrade the RAM to 16 GB (which is possible on the T450, but not the T450s, correct?). So I'm looking at the T450. But, I'm not overly enthused with the non-IPS 1080p screen options of the T450. I was wondering whether anyone bothered with replacing the screen on the T450? Like with the T440/T440s here: http://forum.notebookreview.com/threads/t440s-lg-auo-screen-replacement.743388/

    I think you were talking about T450p which hasn't come out yet. T450 (without any suffix) is just a downgrade version of T450s.

    No, I believe the T450 has the 16 GB slot available. It seems to me though that even when buying an extra screen, it would be about the same price as a T450s. So I suppose no one has probably done it, as it doesn't seem worth the extra effort for the extra 4 GB RAM (and a heavier frame).

    It's interesting that T450 now have 16 gb max while the predecessor (T440) only have 12 gb max. Not so downgrade anymore eh.

    I believe you can replace the lcd, somebody even did it for E450 with T440s IPS screen:

    Hi, I replaced screen on my new ThinkPad T450. Was 1600x900, now full HD AUO B140HAN01.2 . All is working, but you must be careful. When I did it, I forgot disable internal battery in BIOS, so "backlight fuse" (F7) in motherboard died and screen backlight does not turn on. Today I replaced this fuse and all is working.

    So this upgrading must work, but you must be careful.

    P.S. In T450S full HD screen is AUO B140HAN01.3

    P.S.2 Many new notebooks has no backlight fuse, but lenovo installed it. This is good news :)))

    I have a buddy that took the T450S screen and fitted it to a T450 no problem he now has the 1080P screen which is slightly better then the terrible screen that comes with the T450... The t450 screen is really really bad.

    Hello,
    did you have to us a different or an additional cable to go from 1600x900 screen to a full HD screen? Or the HD screen just plugs into the same connector?
    Thanks in advance!

    If I might ask, how did you replace the fuse? I have a X220 where I blew out the fuse during a badly managed screen replacement attempt and would like to repair.

    Does jumping the fuse with a copper wire work?

    I just replaced the laptop screen at Full HD AUO B140HAN01.2, ie cable to connect the screen remains original.
    I recall that in my model T450 was installed HD+ screen.
