hmm...that's interesting....a system hardware update with the strange date (10/24/2013) delivered on different date depending on the user?
My SP2 actually have some power consumption symptoms, I guess. Battery level quickly goes down to %60 or something, and it says 6hr, but suddenly drops to 2hr. I thought this is something related to CPU throttling, because calculation is based on the current draw by the running applications. But indeed, it goes very quickly down to 20% or something, even just using web browser. So, the total battery life is just 3 or 4 hours, practically. Also, I had a couple of times, the OS started by itself, but I thought that's because I accidentally touched power button in the bag. Reading through several threads here, my SP2 might be a victim of the December firmware update.
Anyway, I'm not so bothered, since I use SP2 mostly with AC/DC adapter so I haven't contacted MS. Just for today, I'm testing without AC/DC adapter, and it seems the battery life is much better, but who knows tomorrow......I'll report back.
I usually trust system updates for other PC desktops, but I don't install drivers because they are usually optional. Unless something is terribly wrong, I don't install these third party drivers (don't fix if it's not broken - policy). But SP2 is a MS-made hardware, and driver updates come directly from MS.....what I should do...I'm not so sure after reading all these troubles.
