This machine has been an utter clusterf**k from start to finish. When it works, it's great but most of the time I can't see what I'm doing.
From what I can tell, it's somehow related to battery power and screen brightness. When I run it off mains, the issues eventually go away (provided I leave a video of something running until the driver sorts itself out) but, off battery, 50% brightness or
lower exacerbates the issues. Anything over 75% and the battery power is terrible.
Had no luck getting in touch with Microsoft whilst abroad so it appears that I'm supposed to just deal with it. Still, I've done my fair share of PR on this machine. Whilst sat in hostels, I attempt to show people photos and video. Naturally the display
plays up so I can't show them a damn thing, Safe to say they haven't been impressed with the machine. In fact, I met a guy from the UK who's entire office was supplied SP4s. Which have been returned due to the display issues.
Absolutely disgusted with Microsoft's behaviour. I'll probably do the same and get myself a Dell when I eventually get back into the UK. I'm not giving Microsoft another penny if all they do is give me a refurbished unit which will no doubt end up with the
same problems.
