Question

G7 7588 - Random keys periodically stop working

Apr 3, 2020 11:03PM PDT

I have a year old Dell G7 7588 laptop where random keys periodically stop working on it. My `, 5, 6, Esc, Ctrl, 8 on the numpad, and sometimes g, h. I have all of the latest drivers, I've uninstalled and reinstalled my diver, I've booted in to linux and had the same problem. I thought it was a hardware problem, so I brought it into a shop to repair it. All of the keys worked for them without finding a single problem. After returning from the repair shop, the problem arose again after I plugged in a draw tablet with an hdmi and 2 usb's. It also happened again after I plugged in a usb mouse. Is there anyway that a usb input could cause the keyboard to stop working? How can I check to see if my usb are messing with my keyboard without spending more money? Has this every happened before? The only program that I have installed that could mess with it is throttlestop, which I use to under volt. However, I turned it off and had the same problem.

Two tests.

1. Try an external USB keyboard.
2. If it's in warranty call it in. If OOW (out of warranty) look at YouTubes on how to replace the keyboard. We want to try unplugging and plugging in the internal keyboard because sometimes that connection drops out.

I have an external keyboard, and it works. Unfortunately I'm OOW. I took it to a repair shop and they unplugged and cleaned the connector for the keyboard and saw nothing wrong with it.

I can't tell if it's fixed or not.

It would be worth it to try a new keyboard.
