I have purchased several Dell Venue 8 tablets over the last few months of 2014 for customers using my meter reading entry app. At least half of them have failed to power up at least several times, and two have never powered up again. The one that I most recently had in my possession was finally thrown into the trash can. I have customers in 39 states using my utility billing software. I have tried a Dell laptop with Windows 8.1 which would not recognize a second monitor, nor would its WIFI system work, and, as I just mentioned, several of the Venue 8 Pro tablets. I will not purchase or recommend Dell products again.
I also purchased a Microsoft Surface 3 after all of this trouble with Dell, and within 24 hours of that purchase, it failed to power up as well. I took it back to Best Buy and they could not get it to power up either.
Finally, I believe that I have found a tablet that will faithfully power up. It is the HP Stream 7 with Windows 8.1. So far, it has never failed to power up, and believe me, I put it through some serious testing before sending it to a customer.
