Laptop items got rotated and display has become Mobile PC Display?

I have Windows 7 Home Basic installed in Lenovo laptop. Sometime back the desktop got rotated counterclockwise by 90 deg. May be some keys got pressed by mistake or may be Windows auto-installed something when I was not noticing.
Pressing Ctrl+Alt/=arrow key does not help. I went to Display Settings. But in display dropdown I see only one option: Mobile PC Display. How do I correct the rotation problem?

Laptop runs on battery but not running or charging from power adapter?

I have a Lenovo Y470 on the bench. It runs off the battery till dead, has no power LED but power is present at mainboard from charger. So here are the existing conditions:

Charger is good
19 volts +/- Present at mainboard
No power led when plugged in
Will not Power on
Will run normally off charged battery until depleted
Will not charge battery
So it appears that there's something open between Power in at board and charge circuit. There are no apparent breaks on board and checked all fuses, power resistors, chokes and I don't see any burnt or damaged lans on board. Any help would be much appreciated. If there was only A SCHEMATIC OF POWER/CHARGE and DISTRIBUTION it would be a piece of cake for me.
