Review: William is your new friend! (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: Very useful card, backed by excellent service - 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. Recommended!

## Questions & Answers

**Q: Will this work on a Chromebook?**
A: Hi, the Chromebook is the Linus based laptop running the Google Chrome apps. As soon as the laptop comes with the WIFI connectors eg. miniPCIe or miniPCI, we can use this new diagnostic kit to test. Hope this helps, if need more assistance, please let me know the exact model number, I would like to double check for you, thanks!

**Q: Would this work on a server motherboard? (supermicro x8dtl-if)**
A: Yes, the supermicro x8dtl-if motherboard comes with both PCI and PCIe slots for this new latest PC diagnostic cards kit to work on.
Hope this helps, any question, please let me know. Thanks.

**Q: Where does this ship from?**
A: Hi, this ships quickly in the states. 
Hope this helps. Any question, please kindly advise. Will help quickly again, LifeTime Support on this new latest computer motherboard diagnostic kit. Thanks.

**Q: is there an app for Apple iPhone?  Can it be used without the app?**
A: Hi my friend, thanks for your query.

We are developing the APP for Apple and should take some more time.
Currently, we can use the Android APP seamlessly and view the comprehensive diagnsotic results on the large Android smartphone or Android tabletPC.

Since motherboards technology is advancing, we do need a better and newer latest diagnostic kit with the newer technology in troubleshooting the computers as well than the earlier digital codes display edition diagnsotic kits. 

"Can it be used without the app?"
I am afraid no, we cannot use the newer latest kit without the Android APP.

Hope these help with your concern.
If I can be of more helps, please kindly advise.
Best regards.
