I recently got this laptop and am about to throw it away. Here are some issues with it:
1. The unit does not seem to go to sleep and uses the battery when the lid is closed. If I then disable the registry setting csenabled=0, the unit goes to sleep but then does not wake up and one has to hold down the power button and try at least a few times before it comes back on. My perception is that this model has some serious BIOS issues in how it handles power settings and wake up and in how long it takes to load the BIOS on startup (not Windows, the BIOS).
2. Another issue is that at times, the CPU gets stuck at 0.4 or 0.5GHz and the computer is crawling slow. Very frustrating.
3. No matter what HDMI connector I use including the TB15 docking station, the text on the secondary screen is grainy.
I have been in contact with support multiple times and they have been useless. I have been using Toshiba laptops for close to 20 years now and never had such issues.
My question is: do you all have similar issues and if so are there any remedies for such an expensive unit? I surely hope Dell engineering is paying attention and fixing the BIOS issues. And yes, I do have the latest bios and the latest drivers as of 10/19/2017 from Dell's support site.
