I've seen some new and strange behaviors on my SP3 since last Tuesday's patches came out. For instance, last night after I got home from work, I got out my SP3 and opened the Type Cover, powered it up from sleep by pressing the power button, and it came up in portrait mode. No amount of fiddling would get it to leave portrait mode, though everything else was working just fine. I finally decided to reboot it, so I hit the power button on the main screen, selected shut down and waited while it completed. I gave it a few seconds of being off and then hit the power button to start back up, but got nothing. Tried this several times while holding the power button down longer each time, but still no dice. I then tried volume up and the power button and nothing happened there, either. I was really freaked out by that. I kept trying and on the fourth time, the volume up and power button caused the Type Cover keyboard to light up, so I held the buttons down and it cycled the keyboard backlight on and off exactly four times for about 3-4 seconds each cycle. Then, it went dark and stayed dark, so I released the buttons and waited, but, still, nothing happened. Then I tried the power button again and this time it booted up normally. Phew! That was a relief. Today, the WiFi card disconnected from the network, as it is wont to do on occasion, and when I tried to reconnect, it attempted to link back up, but then failed. After it failed, it showed no available wireless networks. I thought maybe the adapter had disappeared like it does sometimes after a wake from sleep, but it was still there and active, showing no problems (I should have known this anyway as the WiFi icon was still active in the System Tray). I ended up disabling and then re-enabling the adapter and then it began showing available networks again and automatically connected back up to the WiFi network that I use here at the office. I hope that these new behaviors are just really strange and unrelated occurrences, but I'm beginning to wonder about these latest updates. My system has had only two real issues as of late, WiFi randomly disconnecting and slow connection speeds, but has otherwise been quite stable. I guess that time will tell.
