Low-Voltage-Gamer. A 17-inch ultrabook? No, a thick 17-inch device with an ultrabook processor and mainstream graphics. Why does Dell not integrate a standard voltage CPU? Does the gaming performance suffer? Our review with an extensive gaming check gives the answers.

I bought this unit which came with a Samsung 1T hard drive and the drive died one month after the warranty ran out. Prior to that it ran well. It seems these units can be shipped with many different hard drives according to where you buy them. Mine certainly did not come with a Western Digital hard drive. Now i have an almost new laptop that i can't use without putting another $200 in it to have it repaired. I called Dell concerning this and all they wanted to do was avoid my questions and sell me an extended warranty. Their customer service simply did not care that I had bought a product that really only lasted for three months of use since I kept it in the box after registering it for over six months.
I was able to purchase one of these used. I overhauled it by replacing the hard disk with an SSD, and I installed Windows 10 Pro on the system. It feels like an altogether different computer after the hard drive replacement. The battery life is still somewhat disappointing; I can browse the web for around two and a half hours. If I'm using the CPU heavily, that time would be shorter. I purchased it as a desktop replacement for my move to a country where the AC power blackouts are frequent.
