Thinkpads Forum

Sometimes schematics and boardviews are difficult to obtain, so I suggest to post them here. May be useful for those who want to repair their ThinkPads.

X220 schematic + boardview
X230 schematic + boardview
X240 schematic + boardview
X1 Carbon 2012 schematic + boardview
T430s boardview
W520 schematic + boardview

Tools to open boardview:

• BDV : Honhan BoardView
• BRD : Landrex TestLink
• TVW : Tebo View

What's the point in having those "boardviews"?
They tell you absolutely nothing...

@nitrocaster: While I would agree with you, some time ago (2009) it was requested by Lenovo that schematics NOT be posted here, nor links provided to the sources, because they are in fact proprietary material. That they are openly sold on several web sites around the net means that they are available, just not here.

@RBS: I'm surprised that you think that board view files/viewers are not worth anything. Properly used, they can tell you the exact location of parts and how they are interconnected to each other. It's easy to trace SDA and SCL signals so that those signals can be tapped at other (read: easier to get to) locations on the motherboard.

Oh my. So Lenovo is just as Apple. Delete this topic, I'll post these on another forum.

Before somebody else jumps in to correct me, I should also note that Thinkpad schematics can also be freely found if you construct the proper Google search. People have posted the files to their own web sites.

Yesterday, i spent 4 hours looking for t430s schematic and boardview.
Still looking for schematic. If you can find it please PM me.

All that those boardviews show are rectangles and dots, no matter how big you try to make them.
I don't see any connections, any part-numbers, any text, any indication what a particular rectangle might be...
Double-clicking on a dot marks it with a random(?) number, no idea where to go from there.

Yeah, some crash course would be useful on this:)

Have you not thought about exploring what the various menu options are? If you can see the board view, then you at least know how to open a file. From there, about the only thing that can go wrong is that you overwrite, if the program allows it, the data file. To prevent that, simply work on a copy of the original file. In any event, hovering over the icons under the menu line will tell you what they do. If there's a hotkey associated with the action, it's also displayed. From left to right:

Open file(Alt-O)
Close program(Esc)
Rotate Left(L)
Rotate Right(R)
Mirror(M)
Flip(F)
Top(T)
Bottom(B)
Fit(Home)
Zoom In(+)
Zoom Out(-)
Move Up(Up)
Move Down(Down)
Move Left(Left arrow)
Move Right(Right arrow)

All of these actions should all be self-explanatory. The board view program is used with the associated schematic diagram as the part numbers and signal names are embedded into the .BDV file. This assumes that the .BDV file matches the schematic; sometimes there's different motherboards used in the same model. An example would be one system using Intel graphics, versus another that uses ATI.

Open the x230.boardview.11232-1.bdv file and use the Find/Find Component Part (or hotkey D) to enter U42. That should highlight device U42. Why "U42"? That's the part name used in the schematic. Use the Find/Find Net (By Net Name) command and enter smb_data in the first line (caps not sensitive). Note that the text is RED. There's two other lines that you can also specify that will be in GREEN or ORANGE. This allows you to enter up to three signal paths and they will be shown as the related colors. Click the FIND button and you should see several items now displayed in red. Those are the places where the smb_data signal is routed. You may notice a number (729) and a dot. That should be a via where the signal passes from one side of the board to the opposite.

You want to see part numbers on the board? Use the View, Show/Hide Part Name (or hit ALT-P) option and ALL of the parts on the board will have their names listed right next to the rectangles.

I should note that I've seen several different, incompatible, board view programs using .BRD or .BVD or .CST files. Each has their own commands and options but generally they operate in the same way. You can view both sides of the board, pan and zoom, identify parts, trace signal paths and even list the manufacturer part number.

Oops, I must have tried every button EXCEPT View, duh.
Thanks for the clarification.

I only have schematics (below) for T430 igpu model, no boardview

Hi,

I'm desperately looking for x220t schematic and boardview. Anyone have them ? Anyone knows where to get them free or paid ?

Thanks.

Let us know please if that's indeed the X220t schematics.

The X220 and X230 are Wistron Dasher-1 and Dasher-2, respectively. The tablets are Comet-1 and Comet-2 respectively.

I can find schematics for Comet-2 and Dasher-2, but not for Comet-1. It may be that the Dasher-1 schematics are supposed to cover Comet-1 as well.

I couldn't buy this file ( https://www.alexlaptoprepair.com/forums ... s-ok.2332/ )
A lot of file say x220t when it's x220 inside.

The project name of x220t is Winstron Comet-1. Am i right ?

No, it's Wistron Comet-1.

Oh, yes, sorry for the typo.
Thanks for your answer. Annoying not to have a boardview for Wistron Comet-1...

Where can i locate t430u bios ic?

BDV files are openable in GNU/Linux using OpenBoardView.

Looking for T440p schematics.
Mobo made by Compal with this name: VILT2 NM-A131.

Hi, new member here..

Would anyone be able to direct me to where I might find a/the schematic/boardview for a T510, I've had a google 'round, and tried a couple of searches here and there, but to no avail..

Any have any ideas..?

Thanks in advance,
Dalv0

I'm afraid the days of free lunches are mostly over.
Nowadays people want your mullah first.

Schematics and board views are in English.

Find the attached boardview for Lenovo Thinkpad T470/T470S ..
I am posting this to help those who have struggled like me to find the boardview. At last I have to purchase it.

i am unable to open w520.boardview.UMA_H0222-SC.brd attached with this post using any of the 3 s/w. What am I missing.

but that will not link it to the pdf or allow me to trace tracks.

Here are a few more options.
