You have a very small GPU I'm afraid. You need to lower your MiniBatchSize until it works. Also, set your ExecutionEnvironment to auto since you only have one GPU.
If this doesn't work your only option is to use a smaller network or a bigger GPU.
You could just train on the CPU of course, if you don't mind it taking longer. At least that will likely have plenty of memory, and the way GPUs tend to be throttled on laptops it probably won't be much slower.
