It eliminates the hassle of opening a dusty computer case, enabling direct motherboard hardware diagnostics via an external USB port. Please note that this new motherboard POST test card kit includes two USB cables 1. The integrated USB cable (mostly the white color USB cord) on the V8 master diagnostic board must be connected to an Android charger for power input. 2. The second is a dedicated Black Android Micro USB cable, used to connect the V8 master diagnostic board to a computer USB port. This dedicated Micro USB cable facilitates motherboard diagnostics via the USB port. It does not supply power; instead, it transmits the motherboard BIOS Power-On Self-Test (POST) signal data to this V8 master diagnostic board for POST codes diagnostic analysis. If we can troubleshoot motherboard issues independently, this delivers significant time and cost savings. However, DIY motherboard diagnostics still present several potential challenges as below "I am not computer expert don't know much about computer troubleshooting“ Modern information technology has greatly simplified computer troubleshooting and repair workflows. We do not need to be a certified hardware technician to diagnose motherboard issues on your own: all that is required is the ability to connect hardware components via a USB port, operate an Android smartphone or tablet as you normally would, and have basic familiarity with common computer terminology and component names. This all-new Android-powered motherboard analysis kit leverages a dedicated mobile application to handle the full workload of motherboard diagnostics, and will even provide targeted repair recommendations directly within the app. "No professional tools on hand now, it is a technical job to take the PC / laptop apart" This exclusive USB-based diagnostic functionality integrated into the POST test card kit enables rapid, straightforward motherboard troubleshooting via standard computer USB ports. There is no requirement to disassemble the computer chassis or deal with the associated complexity — all diagnostics can be performed through the external USB ports on the PC motherboard. "The PC is so dusty, don't want to get those dust all over the clothes and hands" Traditional motherboard troubleshooting often requires working with dusty internal components, and the mandatory post-diagnostic chassis cleaning adds unnecessary overhead to the entire process. With our proprietary external USB diagnostic functionality, this issue is completely eliminated. All diagnostics can be performed externally, without opening the dusty computer case or ever coming into contact with the dusty internal motherboard components, keeping our workflow clean and efficient. "How can this V8 smart kit help us?" All computing hardware requires regular maintenance, troubleshooting, and repair to maintain reliable operation — from consumer equipment like desktop gaming rigs, all-in-one PCs, laptops, mini PCs, Android mobile devices, and smart TVs, to enterprise-grade server deployments, and regardless of platform (IBM-compatible Windows systems or Apple iMacs/Retina MacBooks).

(Instructions help here too) - Honestly, I would like to meet William someday and buy him a bear. Hes just that good an honest and helpful gentlemen. RARE now days we know. You don't need to write to him with questions. William monitors the shipping, knows the day you receive it and immediately writes to you to see if you have questions, or that there might be something he can help with. Literally, preemptive tech support! Everything good that has been said about William and his awesome Lingvetron V8 diagnostic tool is true. The only down side is, that English is not his first language and sadly that reflects in the user instructions. The work around with this is simple as the tool is to use. Stop, READ, and just try to understand. In his efforts to make the tool as easy as it is. And that is why and were the instructions get convoluted. He try to hard! And that is due to his diligent efforts to provide. Because of the above and his grand efforts, it gets a bit redundant and muddy. His videos seem to reflect the same. However, he is working on finding an editor to help him so this could get cleaned up soon. So, here is your "user tech tip" for the Lingvetron V8 diagnostic tool. (This is what I did and it worked great!) Download the app from William provided emailed link on desertcart. Make sure you have "install from other sources" enabled. Install it and provide the requested permissions. Using the app makes it so easy as William give you everything and instructions right there. No 2 digit codes to chase down. Its all right in your hand! 0. Tool set ups. Once the app is installed, get it connected via Bluetooth. The app itself will help guide you. Look for the little yellow/red highlighted "connect" on the app. It will also provide the "pass code" for Bluetooth link. Honestly, if you cant manage this, you probably have no business using the tool anyway. So, read me here. Read Will's instructions and JUST TRY. Once that is done... 1. All power to computer off. Even the PU switch located on the power supply. 2. Plug the tool in the wall with a standard 5V charger. Not the fancy powerful ones. Just a cheep 5V will do. Plug it in with the USB that is hard wired to the tool. A green light shows it powered. Blue Bluetooth light will be blinking showing ready to connect. Pair it with the devise your using now. (Note hints above) 3. Locate the provided standard USB cord. Plug it into the V8 tool and the other end into the computer. Preferably straight to the Mother board and not via the case. 4. Reach down and turn on the power supply switch to send power to the computer and IMMEDIATELY hit the power button on the case to fire up the computer. By the time you get up off your knees from reaching around the back of the computer the diagnostic will probably be done. Follow its instructions and suggestions provided. Its just that simple!!! Pair the V8 tool with a good power supply tester and you will never be guessing or swapping components to test ever again! Yes, sorry. Mr. William does need an editor for his instructions. But that's OK because we need his tool and are all patient and smart enough ourselves to work with him on how to use it. You don't even need to contact him. He will contact YOU and be right there to help. Thank you my dear friend William. Your a God send and I so wish had something like your magic V8 too decades ago. Cheers Michael Review: Nice gadgets - Like the way it was delivered.

Cheers Michael ### ⭐⭐⭐⭐⭐ Nice gadgets *by J***M on 23 November 2019* Like the way it was delivered. I havent try it that much,coz i already fixed my pc when i got it,the instructions video are very helpful. ### ⭐⭐⭐⭐⭐ Very useful card, backed by excellent service *by M***S on 12 September 2019* This card helped me to troubleshoot a tricky problem and saved me some money along the way! A newly-built PC would usually fail to POST. Once or twice, I got the BIOS to load, but soon it would crash. Suspecting the mobo, I returned it for an exact replacement. But the replacement mobo behaved similarly. After thoroughly checking out the RAM and CPU heat sink, I wondered: could the new CPU chip be DOA? The PSU worked with an older mobo, so I could probably rule that out. Or, was is possible that I got a second bad mobo? This had me stumped. I found some discussion of this PCIe analyzer card (KQCPET6 Type B) on the Internet, and decided to order one. Since it was half the price of a new mobo, and a quarter that of the CPU, I figured it might help to avoid spending more money. Before the card arrived in the mail, I received a friendly message from the vendor, with URLs to the PDF documentation. (The card is part of a kit, which can also be used to troubleshoot laptop PCs and some mobile phones. I only used the card with a PCIe bus, but it's very versatile.) Once the card arrived, it fit easily in the PCIe slot and displayed all kinds of useful information on startup. I could see that the CPU was working and the PSU supply voltages were okay. The card also performs a "stability test", which my system failed. The card comes with extensive documentation, but as a noob to PC troubleshooting, I found some parts a little difficult to follow. In places, the English was a bit curious, as the original documentation was written in Chinese. I contacted the vendor for additional guidance. For the price, I wasn't expecting too much, but I received a prompt and very helpful reply. We exchanged a few more messages and he got me on the right track with some very helpful troubleshooting advice. The KQCPET6 helped me to determine that the second mobo was also defective (what are the chances??). I returned it for a new one (different brand!), which then worked flawlessly. If you like building PCs and find yourself scratching your head over one that won't POST, this little card could save you money and guesswork.
