I see this and have to try a factory reset to be sure the OS is fine. Before I do that, I test the hardware with a bootable OS like Linux. Since I am just testing hardware, no Linux knowledge is required.
TL:DR, Filed a claim on my laptop through the warranty company to receive repairs on unresponsive keys and broken sound. Servicers found none of the issues I described. When they sent it back, the issues are still here and I'm -$400 for an "inflated battery" and shipping costs which were not covered by the warranty. Please help me...
A couple keys on my Dell XPS 15 keyboard are frequently unresponsive, making typing very frustrating.
The keys that misbehave most are "w" and "2".
I have also noticed that "caps lock" sometimes has the issue as well.
This has been a problem I've dealt with for about 6 months so I finally decided to send it in to get repaired with the warranty.
The servicer was unable to find any issues with the keyboard and instead noticed an inflated battery, which was not covered by the warranty and I was slapped with a nice big bill. Anyways, I knew for a 100% fact that the when my laptop returned the issues would still be present and to no surprise they are...
Any USB keyboard I plug in works 100% flawlessly. I have deleted the keyboard drivers and reinstalled them several times but the issue persists.
When filing my claim, I also noted this issue which I have that can be found heree in a Previous Post I have faced issues with the sound since before april 2016 and the servicer was unable to find anything wrong with the sound.
Please, possible causes and solutions, how I can fix them myself, or prove to the servicer that the issues I've described exist.
