ОтветыCan I swap the r1 motherboard for the r3 motherboard?No, the R3 has a different port layout and appears to have a different heatsink location. I've never personally owned both the R1 and R3, but Dell Forums suggests that there are a lot more incompatibilities than just the ports. I suggest the Eurocom Monster 1.0 if you're looking for a new 11" gaming computer, it has a lot of options, even server level processors with the i7-3 Extreme CPUs and up to 8TB storage, all packed into a sleeper netbook look that won't get your laptop stolen at a Starbucks. Besides that though, you're better off reselling for parts on eBay and buying something even newer than that.
ОтветыGlass only repair with dry iceIt appears as though a literal freezing machine like the one mentioned by the users above will do the trick. Dry Ice (solid CO2) doesn't appear to be cold enough.
ОтветыWhy did my screen change color my pictures look like negatives nowYou might have high contrast mode enabled. With all the different flavors of Android around, I can't help you specifically but you might want to look at Settings and see if High Contrast is on in Accessibility or Display. You haven't provided much information about what caused the issue or if you've tried to turn it off and back on again. Speaking of, try turning it off and back on again, along with the things I mentioned earlier.
