Hi end lap tops are great for being on the road. When m original shot c###% after a cup of coffee landed on it, the wife bought me a new one the computor store had on sale. It was great when I was in the basement or bed room. Out on the road it was worthless. Seems it didn't have the proper card internally. Since moving to the shop the daughter traded computors with me. I owe her a lot as now I can use it in the shop and where ever there is a link in this great land.
But, as stated use the power cord as batteries are only good for a couple of hours at most. DOC Holliday
