Speed mode repair through reballing?
I have an old VAIO SZ which suffered the infamous glitchy graphics and hang when booting on Speed mode. The laptop, fortunately, still booted fine on Stamina mode, however I heard that these laptops run good as new when the Nvidia chips get reballed. Is it worth to give it a shot? I've seen tons of hairdryer repairs done on Nvidia-equipped laptops, but I wanna do a reball instead.
