A few weeks ago, I developed two problems with my Dell XPS 12 that seem like they may be related, but unfortunately, I haven't been able to solve either.

1) The first issue is that sometimes when I turn on my laptop (this has been progressing to EVERY time), it emits a series of 8 short beeps.  I can then turn it back off and on, and it starts normally.  (Except for today, which took several tries.)  I found that 8 short beeps is the beep code for the LCD screen.  However, I'm not having any screen issues.  I also ran the full diagnostics from Dell support and passed everything, including all LCD tests.

2) The second issue is regarding screen resolution.  Again, not EVERY time, but sometimes after my laptop has been in sleep mode and I "wake" it, the screen has resized from its normal HD (I have it on the recommended screen setting) to a much smaller, square width, resetting all my windows with it.  I can set it back, but it's VERY annoying to keep having to do this!  I have tried a number of fixes I found online, including making register alterations and changing when the laptop sleeps, but none has helped.

I'm by no means a computer expert, but I can find my way around with guidance, and I would appreciate any help with this!!!
