Lenovo LB 820-2877 (820-2877) — 76-page schematic
Open in new tabDownload PDFAbout this Lenovo LB 820-2877 (820-2877) board
This page is generated from the board file itself, so the map above is the manufacturer layout rather than a redrawing of it. The board carries 1,692 components and 1,668 named nets across 6,721 pads, with 170 test and probe points marked in amber for when you want to measure rather than desolder. About 99% of the components are surface-mount, so the top and bottom side filter is usually the difference between finding a part in one pass and searching both faces.
The schematic is 76 pages and covers the usual blocks you would expect on a board this size — input power, PPBUS/G3 hot, rails, clock, storage, display and audio output. The page index under the viewer gives you the heading on each sheet, so you can jump straight to the block you are chasing instead of scrolling.
Check the board number before you order parts: several of these machines shipped with more than one board revision, and a component taken off the wrong revision frequently has the same designator and a different footprint.
Frequently asked about the Lenovo LB 820-2877 (820-2877)
What board number is the Lenovo LB 820-2877 (820-2877)?
The Lenovo LB 820-2877 (820-2877) uses logic board 820-2877. There is more than one revision of some of these boards, so check the number on the board itself against the one on this page before you order a part — a component from a different revision will often not fit or will not reference the same nets.
How many components and nets are on the Lenovo LB 820-2877 (820-2877)?
The board file records 1,692 components (1,676 surface-mount, 16 through-hole), 1,668 named nets and 6,721 pads, plus 170 test and probe points. The board measures 175.39 × 118.24 mm. Roughly 99% of the parts are surface-mount, which is why the top and bottom side filter matters — a lot of this board is only reachable from one face.
How do I use this Lenovo LB 820-2877 (820-2877) boardview?
Type a designator such as a component reference, or a net name, into the search box above. A net name takes priority and highlights every pad on that net across the whole board. Clicking a component outlines it in white and lists every pad it has with the net each one belongs to; clicking one of those nets jumps the highlight to the whole rail. Use the side filter to isolate the top or bottom face, and the designator toggle to hide the reference text when you are zoomed out.
Does the Lenovo LB 820-2877 (820-2877) come with a schematic?
Yes — the full 76-page schematic is embedded above and downloadable as a 1.6 MB PDF. The page index under the viewer lists the page headings so you can jump to a circuit rather than scrolling through every page. The schematic's text layer is also published as text on this page, which means you can search it with Ctrl+F on any browser, including the ones where a PDF in a frame refuses to be searched.
Can I download the Lenovo LB 820-2877 (820-2877) boardview file?
Yes. The original 317 KB BoardView file is linked below under downloads, named lenovo-lb820-2877.BRD. Open it in BoardViewer or any other tool that reads the .brd format. The interactive viewer on this page is for looking things up quickly; the .brd is what you want when you are at the bench with the board on the mat.
Schematic text — searchable without opening the PDF
A PDF inside a frame is invisible to a crawler and often unsearchable in the browser. Here is the schematic’s text layer as plain text, so you can use Ctrl+F on this page to find a rail name, a component reference or a page heading.
