Hi everybody! I have a Lenovo Thinkpad e540 20c6-008sus which came stock with a HD 1366 x 768 display panel, I see that there were originally options for very similar models from the factory with the Full HD 1920 x 1080 display panel. The 1366 x 768 panel in my computer right now is mounted to the hinge-assembly with side-mount screws, and the 1920 x 1080 panel that came in the very similar models mounts to the lid itself with top and bottom brackets. I know I will also need a 2 lane video cable to support the 1920 x 1080 panel, but I don't know if the top and bottom brackets are 'plug and play' with the hinge-assembly in my laptop. Has anybody done this upgrade and can you tell me more about mounting the factory Full HD panel to the hinge assembly in my e540?
Solved! Go to Solution.

Thank you so much for the part number again! I've found a couple pictures to demonstrate what I see as the final hurdle impeding my upgrade to Full HD on my Lenovo E540. I think I also need a different lid to mount the screen to. I've focused on the upper left mount point for the Full HD screen (part number 04x0529), if it were to be installed. There appears to be a significant difference between the inner structure of the lid behind the screen of my computer (natively HD at 1366 x 768) and another E540 that came with Full HD 1920 x 1080 out of the box. Is there a part number for this slightly different lid as well? The part number for the lid behind the screen on my E540 is AP0SK000E00 (the 30 pin edp connecter is labeled wedge) and I've found a couple references to AP0SK000200 (labeled as flat) in relation to Full HD E540/E531 models. It looks like AP0SK000200 has the mount points for the upper and lower brackets of the Full HD screen, but I don't know if it's compatible with my computer (the distinction between wedge and flat seems to be the location of the 30 pin edp connector being either in the middle lower back right quadrant of the screen [wedge] or at the bottom right edge of the screen [flat]).
Here is the picture of my E540 showing where the upper left corner of the screen would be mounted
Here is the picture of another E540 that came with Full HD out of the box
And here is a link to a lid that might be compatible with my computer and looks like it has the appropriate mount points for the Full HD screen but I don't know what is the difference between a Wedge and a Flat model or how to verify compatibility

Hi Bl8demast3r, just to clarify you're looking at upgrading your E540 from HD 1366 x 768 to Full HD 1920 x 1080 and you're starting with (1) rear lid/cover part number ap0sk000e00 (2) HD screen part number n156bge-e11 (3) 1 lane video cable part number dc02c004e00 and you're looking to upgrade these using (1) yet to be determined rear lid/cover with the Full HD screen mount points [maybe part number ap0sk000200 or ap0sk000900?] (2) Full HD screen part number FRU 04x0529 [is there another Full HD screen you're looking to use here?](3) 2 lane video cable part number dc02c004600. Does this read about right? Also, If you use either of the aforementioned rear lids (ap0sk000200 or ap0sk000900) and they work out then I'm very interested to know. Thank you.

Hi, Sorry for the late reply I've been a bit busy the past few days but to answer all your questions; Yes I have a 1366 x 768 LCD that I'm trying to upgrade to 1920 x 1080. The part numbers you have mentioned are all correct I will link screenshots of all my stock parts for anyone looking at this in the future. Imgur link
So initially I thought this upgrade would be a cake walk going by the other pretty in depth thread found here. Unfortunately, that was not the case at all... What I found out is that the OP of that thread already had a 1920 x 1080 screen installed and he just wanted to replace it so he already had the "Flat" configuration rear lid. The E540 comes with 3 completely different rear lids. As found in this Amazon post here they mention the part numbers and codenames for each type of screen configuration:
Wedge: 1366*768 04X4292 04X5682 AP0SK000E00
Flat: 1920*1080 04X1118 04X5680 AP0SK000200
Touch: 04X4276 AP0SK000C00
Each of these lids use completely different mounting configuations.
So, if anyone is thinking of upgrading their 1366 x 768 E540 to a 1920 x 1080 screen be prepared for a bigger job than expected. Not only do you have to find a rear lid with the proper configuration for a 1920 x 1080 screen you also have to buy the hinges because those are different as well. Not to mention it would be a pain to have to transfer over all the tech such as the camera and antennas. Oh and I'm not sure but I think the front bezel is also different since they as well have different part numbers.
I guess on the bright side of things the cable that I have worked fine with the 1920 x 1080 screen I bought. I guess if anyone is wondering I purchased the LP156WF6 SPB1 LCD screen. I don't believe they make a 1920 x 1080 screen that would fit inside of a "Wedge" configuration since Lenovo has 3 different configurations for each display they use, if there was a 1920 x 1080 screen that would work in a Wedge configuration Lenovo would have just saved some money and made every E540 a Wedge model instead.
I really hope this thread helps someone in the future researching this laptop since the information is a little sparse for this model. Anyways I think I will be returning the screen I bought because I didn't want to pay anymore than I already did to do the upgrade. The rear lids alone can go for $50+ and I don't think that's worth it at all.

Thank you so much Bl8demast3r! after determining the rear case/lid I was next going to find out about the hinges, and whether or not the bolt configuration for them matched the frame mount for them. Yep, If you had the complete hinge assembly with the rear lid and front bezel to match and a nice 1920 x 1080 screen to go in it along with the 2 lane video cable all just lying around then maybe the project would be worth it, but otherwise I think it's getting towards $150-$200 worth of parts at which point it's time to ask if it isn't worth saving up for a better laptop. Maybe It would work if you found a full HD Lenovo e540 for sale with a fried motherboard for $20 on craigslist or something, but buying all of the parts individually begins to be ab investment that is not worth the return. Thanks everybody for pitching in here!
