Chosen Solution
I bought this from Ebay. Replace the SSD and cracked screen. It will not work with the internal keyboard and trackpad. I have tried reseating the cables. The previous owner said he had no problems with the keyboard. It works fine when I hook up a usb keyboard and mouse.
hello Brian, a somewhat common issue. This involves corrupt data lines from the ALTERA MAX V, sometimes due to an open resistor on one of the said lines. However, there are other issues that can cause this as well. It is possible to repair, if you are interested in sending it. I would be happy to help with this or to answer any other questions you may have. -Brenden
If this is from eBay, not that as I seller I like it when people do that, but you can go back and tell them that it’s not as described, and you’ll probably win the case. With that said, try working it out with your seller first and see if you can maybe get a partial refund if you don’t want to ship it back. If both the internal keyboard and trackpad are not working, it’s possible the entire circuit isn’t getting power properly. I had the same machine a few years ago and the backlight for the keyboard quit, and that’s a seperate DC-DC step up boost converter that I didn’t bother to troubleshoot because it was just a keyboard backlight I didn’t need. Perhaps start by measuring carefully for voltage on the keyboard connection. If reseating and a new keyboard(most likely not findable easily) don’t solve this issue, there’s probably some motherboard repair to be done.
