Welcome to ELC Audio Engineering. Please read the description carefully before offerding. In case you're curious about our username (tungsten*ware), here's the short version: I live on Tungsten Drive, and this connection is not a coincident. Tungsten, known for its remarkable properties and versatility, finds extensive application across various industries, ranging from manufacturing and construction to electronics and healthcare. See footnote [0] for more info on tungsten.

As with all of our listings, we do NOT use stock photos or canned descriptions [1]. I've noticed other sellers using our headlines, descriptions, and photos, but these are ELC's original descriptions and photos. What you see in the photos is exactly what you're offerding on. Photos are an integral part of our descriptions: PLEASE VIEW ALL PHOTOS CAREFULLY. If something isn't clear, please ask before you offer. Please read the description carefully so you know exactly what you are offerding on.

Shipping: International buyers must choose 's International Shipping Service. Note: does NOT automatically adjust for the shipping cost of combined items. If you purchase multiple items that can be combined into a single shipment, please request an invoice so I can combine items to save you money. We charge for actual shipping only (i.e. no added fees) using 's shipping calculator. Please read [2] for additional shipping info.

With very few exceptions, we do not accept returns. Read [3] for further details regarding this policy. Nothing in this listing is misleading--check our response as a seller [4].Many thanks for keeping a positive buying and selling experience!

This listing is for a unique Lenovo ThinkPad P51 with professional engineering software licensed exclusively to this machine's ID / HW fingerprint. This P51 ThinkPad was configured around late 2019 / early 2020 to mimic industrial computers located at manufacturing facilities in China, Vienna and Hungary. Please note that I have several SIMILAR laptops for sale, all from same time period and ownership.* By virtue of this "industrial clone", troubleshooting, support, and script-writing could be done remotely. *I worked closely with engineers from RIM / Research in Motion (AKA BlackBerry) while working in Austria and China. The main computers were part of an automation systems used to manufacture speakers and receivers used in BlackBerry, Nokia, and other smartphones of that time. Another big NOTE: The ORIGINAL NI installers (i.e., the LabVIEW software, to include drivers) did not come as a standard disc set or development suite, but were customized packages provided on DVDs and flash drive(s). The software and license files can be found on the main drive as well as media (DVD, flash drive) to be provided with this laptop.

At the heart of this ThinkPad P51 is an Intel Xeon CPU at 3.00GHz. Installed memory is 32GB DDR4 RAM. The 512GB Samsung NVMe SSD has very low hours (735 hours ON time). Getting to other important details, the LabVIEW installation leans heavily towards Sound & Vibration and NI Vision. Most of the NI software actively licensed to this computer can be seen in the slides. Note: The NI LabVIEW 2015 and 2017 software is now past its maintenance contract and, as such, cannot be upgraded beyond drivers and service packs without purchasing wholly new licenses--all at a cost of many thousands of dollars! The license files are exclusive to this computer's hardware IDs; i.e., the license files are not transferable, but can be removed and reinstalled on this computer. It is best to keep a backup copy of the license files in the event Windows needs to be re-installed (or if you want to downgrade to Windows 11). Please view all photos, as they're better descriptors than my writing. Thanks for viewing! Buyer pays actual shipping on 9 lbs. A brief overview of the slide deck follows:01. Main image, with snapshot of NI-SCOPE (simulation running) along with LabVIEW 2015 and 2017 Professional. Note: If you get NI's update notifications, make sure they're not trying to sell you on a more recent version of NI software because this will mean buying all-new software (at many thousands of dollars!).
02. Backlit keyboard shown illuminated at startup.
03. Sign In: The current username is simply "National Instruments".* A password has not been set. Additionally, the BIOS is unlocked, so you're free to make changes as you please. *(Note: This laptop was NOT owned or maintained by NI. The NI name was originally chosen to differentiate personally owned computers from factory-owned computers.)
04. This laptop's FHD (Full High Definition) display is very bright and vivid.
05 thru 09. Different views of the laptop, showing minimal wear. This computer is in EXCELLENT working and cosmetic condition, with very low hours of SSD ON time.
10, 11 and 12. Mostly complete details regarding the NI LabVIEW Pro software licensed exclusively to this computer.
13. BIOS screen, showing 32GB installed RAM and the Xeon CPU.
14 and 15. Example of HW (hardware) diagnostics; specifically video and graphics. This computer passes all HW diagnostic tests.
16 and 17. Screenshots, showing basic info and the Device Manager, respectively. The Device Manager has been expanded to show the NVIDIA Quadro GPU and Samsung SSD.
18. The 512GB Samsung (for Lenovo) NVMe SSD has only 735 hours of ON time (approximately 31 days).
19 and 20. MATLAB and MATLAB add-ons. I do not know the full extent of the MathWorks MATLAB R2019b Pro licensing, so it is being thrown in as a bonus only, with no guarantee insofar as license longevity (it may be perpetual or indefinite--it's working well now!).
21. MS Visual Studio 2010 Pro is installed (works with certain LabVIEW features).
22. Making sure this laptop reaches you safely.
23. NI LabVIEW Professional and NI-SCOPE (noting that NI-SCOPE does not require a license, but almost everything else does. Licenses, as shown, are exclusive to this computer).
24. Lenovo's default desktop. Office is a part of the Lenovo's software bundle, but it is NOT activated (an Office license seat requires purchase or your Microsoft account). An older version of Office Enterprise is activated, which made this computer backward-compatible with other computers.
Bringing us back to the start... Thank you for viewing!

Reminder: International buyers must choose 's International Shipping Service. Thank you for viewing!

I do not entertain best offers, nor do I end sales early. Item will be sold to the high buyer (heck, a single buyer might get a fantastic deal). Items not paid for after 72 hours will be re-listed.

[1] We do not "borrow" photos from other sellers, nor do we use 's database. Other sellers have used our photos (noting we have zero affiliation with those sellers), and why I have added the tungsten (atomic symbol W) coffee mug for personal identification. If sellers aren't using their own photos, then you really don't know the condition of what you're buying or offerding on.

[2] I pack items with great care--the same way I'd like to receive a delicate or valuable item. Akin to other sellers, we do not have control over shipping costs or carrier delivery time. Small- and medium-sized items will be shipped via USPS Priority Mail. Larger parcels will be shipped via FedEx Home or FedEx Ground. Unlike Jeff B, neither nor I operate our own shipping services--this means no "Prime", free, or overnight shipping (although we ship some items for free depending on size).

[3] Why we no longer accept returns: In a few unfortunate incidences, buyers with buyer's remorse had intentionally damaged perfectly good equipment in order to receive a refund. In other instances, buyers were simply incompetent: Equipment was damaged because those buyers did not know how to properly use or handle it; yet, they wanted refunds because of the damage they had caused. Bottom line: No returns! If the wrong item is shipped or if there is a gross oversight on my part, I will promptly refund or exchange the item and pay for return shipping. Please understand that what you're buying is USED unless it's clearly stated as new.

[4] I'm batting 100% positive response after nearly two decades of buying and selling on *. I kindly leave positive response for those who do the same. Prior to my current username, I had over 1500 combined selling and buying reviews with 100% positive response. *(I changed my username since re-starting on in order to reflect my current business.)

[0] Tungsten's excellent electrical conductivity and thermal stability make it a preferred material for electronic and electrical applications. Tungsten wires and filaments are commonly used in incandescent light bulbs, electron tubes, and electrical contacts due to their ability to withstand high temperatures and maintain consistent performance. Because I’m an advocate of VT amplifiers, I'll add that large transmitting tubes have carbonized tungsten filaments containing a small trace (1% to 2%) of thorium. Of all metals in pure form, tungsten has the highest melting point (3,422 deg C, 6,192 deg F), lowest vapor pressure (at temperatures above 1,650 deg C, 3,000 deg F), and the highest tensile strength. Its density is 19.254 g/cm3, comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead.
