I've had this laptop for about 2 weeks now. My first problem was documented here and resolved after Dell replaced the touchpad:

Since I've had the computer, I've been having trouble during start-up (usually from Sleep mode). Occasionally the laptop won't fire-up again and I'll get the following error: "DPC_WATCHDOG_VIOLATION"
Is this something that is normal for Windows 8.1 laptops?! The notification then said that the laptop had to rubuild its "metadata"... This has now probably happened about a dozen times since I've had the laptop.
I was not happy with the fact that I needed to get new hardware installed after having the laptop for two days.... and I'm certainly not happy about the probelms with start-up. Honestly, for the price I paid for this thing ($2K+), it should run flawlessly.
A secondary problem happened this morning... the touch screen stopped working. Admitedly, the laptop was running hot due to inadequate ventilation, but should that cause the touchscreen to stop working? It fixed itself after I rebooted.
Please help.
