T400 900p LED screen upgrade

#1 Post by jacekwalenty » Sun Jan 10, 2021 6:29 am

After my old screen developed some white spots I decided to upgrade to 900p.
The old one was LED so I wanted the same.
Got the screen, than the cable and the led board (the old one wasn't compatible).
Almost happy with the result. The last bit is the bezel.

The HMM says it should be 45N5856 which is quite difficult to find.
Sellers often don't know the difference and advertise bezels as 'fits all T/R400' etc.
Is there any way to recognise which is which only by looking at the picture ie on Eaby?

There is one seller with 45N5856 on the sticker on the back of the bezel but it also has 42X4865 on the plastic.

Is this the one I need?

45N5856 is a CCFL-bezel.
That picture says 45N5858 which is the LED-bezel with webcam.

Thanks for clarification. The donor laptop was 2767-E3x. Page 320 HMM says the bezel should be 45N5856 but you're right that's not for LED backlight.
Do you think that bezel from the picture is what it says on the sticker 45N5858?

I can't say if the pictured one is OK.
Last time I had a T400 is about 5 years ago.
But if you already have a T400 with LED-screen (as you stated in your first post), why buy another LED-bezel?

The old bezel does not cover the 900p LED screen properly.
There is about a milimetr difference to top-bottom and about a half a mil to the sides.
See here https://imgur.com/a/cR2iAf9
The old screen on top of the 900p plus how the old bezel covers the 900p LCD.
The old bezel is 45N5851 or 45N5777 - both numbers are visible on the back.

I have several T400s with CCFL WXGA and 900p and WXGA LED.
I can swap the bezels between them and they fit perfectly.

The 900p LED screen is different, none of the bezels I have will sit on it properly :(
