Frequently asked questions
Everything about how the index works and how to use the files.
What is Enginerys?
Enginerys is a free search engine for electronics-repair documentation. It indexes the names of schematics, boardview files and BIOS dumps posted in public Telegram channels, groups them by board number, brand and format, and links you to the original Telegram post where the file can be downloaded.
Where do I download the file?
Every result has an "Open in Telegram" button that opens the exact post in the source channel. Download the attachment there with the Telegram app or Telegram Web. Enginerys does not host, mirror or modify any file.
How do I find the right schematic for my laptop?
Search by the board number printed on the motherboard — for example LA-E891P, NM-B452, DA0X8BMB6F0 or 820-00165 — not by the model name on the case. One laptop model can ship with several different boards, and the board number is the only identifier that matches a schematic exactly.
What is the difference between a schematic and a boardview?
A schematic is the electrical diagram: it shows how components are connected and which voltages to expect. A boardview is the physical map: it shows where each component and net is located on the PCB. Technicians use both together — the schematic to understand the circuit, the boardview to find the part.
Which program opens boardview files?
OpenBoardView is free, runs on Windows, macOS and Linux, and opens most repair formats (.brd, .bdv, .cad, .fz, .asc, .bvr, .tvw). FlexBV and BoardViewer cover the rest. The format reference on this site lists the right viewer for each extension.
How often is the index updated?
Once a day. The crawler reads only new posts from each tracked channel, so files published today normally appear in search within 24 hours.
Is Enginerys free?
Yes. Search, browsing, the guides and the JSON search API are free and need no account.
A link says the post or channel does not exist. Why?
Channels are sometimes deleted, made private or have individual posts removed. If a file has more than one source, the file page lists every post where it was seen — try the next one. Dead channels are dropped from the index during the daily update.
Are the files safe?
Schematics (PDF) and boardviews are data files and are low-risk. Be careful with archives that contain executables, and always back up the original chip before writing a BIOS dump from any source. Enginerys cannot verify the content of third-party files.
A BIOS archive is password-protected. Where is the password?
Channels usually put the archive password in the caption of the post or in the channel description. Open the post in Telegram with the button on the file page and read the text under the attachment.
Can I add my Telegram channel?
Yes — if it is public and regularly posts schematics, boardviews or firmware as file attachments. Send the @username to the contact address on the About page. Channels with no files, paid-only content or invite-only access are not listed.
How do I ask for a file to be removed from the index?
Use the removal procedure on the DMCA page. Because Enginerys stores only the file name and a link, removing the index entry does not delete the file from Telegram; the channel owner or Telegram must do that.
Does Enginerys have an API?
There is a read-only JSON endpoint at /api/search.json?q=… that returns the same results as the search page, and /api/stats.json with index totals. Automated clients and AI assistants are welcome to use them with reasonable request rates.
