They wrote this back: I immediately lost all stamina ‒ all will to move forward. My unit was 3-6 months past the 1 year warranty, and I just assumed that's the conclusion they'd reach, at which point I'd be out at least $100. I should have at least written back to ask if they'd unconditionally fix it once they realized it was the battery manufacturer's fault. However, three more months have passed since I had that dialog. I put it out of my mind and moved on. I'll always regret ordering it directly from Vaio, instead of getting it from the MS Store where I could get an extended warranty (it was either cheaper-than-usual or free if I recall correctly). There was no reason to do what I did. Let us know if it turns out differently for you.
