A:AnswerI can play World of Warships on 1080p with medium settings and 30-35 fps. I can play 768p on high settings with 32-37fps. It is obviously not a gaming laptop, but you can play some 2015 and 2016 AA/AAA games on medium or better settings at 768p and low or medium settings on 1080p.
A:AnswerThey are on the bottom and while the sound is obviously better when I have the screen flipped over so that the speakers are more exposed i've found that the quality is still pretty nice in normal laptop mode, as long as the computer is on a hard surface.
A:AnswerGood question: call Dell Support and ask them. I did not see one on their website. There are several after market alternatives you can search for on the internet.
Alternatively, purchase a rectifier that you plug into your van's power port that converts direct current into AC. Auto parts stores, internet, camping supply stores and Wal-Mart carry them Then you can charge the laptop with its included charger with the added advantage of being able to run other AC accessories or electronics.
A:AnswerYes...this can be "the one". Photoshop will take advantage of multi-threading by the CPU. If you do a lot of RAW format photos, you may want to use an external drive to store them since they take up a lot of storage. While 512GB is BIG.....it can disappear quickly with large photo files. 12GB is more than adequate. If you use the online version of Photoshop, it will be even faster, assuming a fast internet connection. I prefer local software.
