January Upgrade for mi have made the opposite effect, after few minutes in Web Game at full screen, in Upper and in Bottom of the screen there is 2 vertical black lines, and they are hardware problem, if you grabb the scree there is no line on graphics, if i turn off for 1h and reopen windows these line disappear.
I was thinking of trying new Thermal paste.
I've searched around to figure out how the liquid cooling works and what is the actual "liquid" used. So far I haven't found info on it.
The hypothesis is that maybe it is leaking or evaporating because at least in my case the problem has been gradually increasing. For a while putting a fan on the back fixed the problem, but this fix is no longer effective for me most of the time.
It wouldn't be hard to make a small hole in the copper pipe at the right place, add some liquid and solder the thing shut again but which liquid and how much?
my sp4 flickering started from a narrow bar at downside of the scren and during a month transform to a whole scren flickering, I use your solution and it makes the flickering reduced in size back to what it was at first.
my Surface 4 is also getting worse day by day (flickering starts 3 years and 4 month after buying..... of course no computer, tablet, phone should be older than 1 year and a half....customers have to support MS ).
I, too, tell everbody NOT to buy these products. If MS have given me an answer to my problem, even if I have to pay some €, I could see this different. So they stole my time (diagnostic tools, setting back, erase all apps, they asked me to send a video, lenght at least xx minutes) and NOTHING ever happened to help me.
So don't buy a MS computer'!
