I have two HDs in my Macbook Pro 15 in late 2009. I installed bootcamp and updated to Mavericks. My Windows partition in running Win7 Ultimate. I set the the boot disk in OSX to be my windows partition and now my laptop doesn't recognize me holding down the option key to choose which partition to boot. When windows boots i have to start the on screen keyboard and then close it for my keyboard presses to be recognized. The quote key causes the option and control keys to stick and delete doesn't work at all. I would use the bootcamp panel to switch back but it didn't install. i would really appreciate any help because i'm behind in my web dev projects and don't want to reinstall OSX because i'll lose my data, plus i took out the disc drive for my other HD.
You should try reseting PRAM.
If it not helps than probably some key are stuck and it cause other keys don't work.
Try to find and fix broken key by using this or this manual.
If it not helps, than it probably hardware keyboard problem.

This is a weird one. I turned Airplane mode on awhile ago and now cannot turn it off.
I've tried fairly extensive troubleshooting based on what I've found on-line, though most of it is just a rehash of the same advice.
Confirmed the physical WiFi switch is On
Tried Function + F3
Tried Function + Print Screen
Disabled and enabled the network adapter
Not sure what else to try. Here's a screenshot showing relevant settings. You'll see that the Airplane switch is toggled on and is actually disabled.
Try booting in Windows 10's safe mode and changing the setting or using Registry Editor again. It's possible a driver or something got stuck and is disabling it.
In my case, there is a switch on my laptop body. If it is there and it's off then turn it on.
That's it!!

So I took my laptop (a Lenovo Yoga 2 pro) in to best buy after it had water spilled on it. They said they'd fix it under warranty and I left it with them. A few days later I came to pick it up, but with only one problem. I gave them the laptop with windows ten as it was installed during the free upgrade period. I got the laptop back with windows 8. Best buy basically said tough titties and told me they couldn't do anything. Would I be able to install windows 10 to it with no problem, or would I have to buy a copy. I heard you can install it and use the windows 8 key it came with.
What does everyone think?
So far I know, you can activate and install Windows 10 with the key of your old Windows version only if it's the one with which you upgraded to Windows 10. However it could be also possible to use other keys according to this link. Here is also shown how to reinstall Windows 10.
How to reinstall Windows 10 with your old Windows 7/8/8.1 key
Anyway because it's Windows 10 you also have a digital license which is linked with your account. So it's also possible to reinstall Windows 10 without a product key requiring only to log in with your Microsoft account. You can read yourself, just scroll to the section where it's about how to activate after reinstallation.

I want to ask, if I format my computer (currently running windows10 genuine) and use some other OS for a while and then again install windows10, will I be able to reactivate my windows with the same key which is working currently on my pc ?
That should work just fine, provided you can install the same version. A key for Home won't work on Pro and vice versa, and there are also OEM versions and Volume License versions, so make sure which exact version you have.
If you have an installation CD or an ISO for the right edition (the one you have the key for) you'll be fine. You can re-install from that CD multiple times.
If Windows came preinstalled, you'd better make an image of the hard drive which you can restore later.

I don't understand that StackExchange, where I can post question about computers, so I think, this will be good.
Friend of mine wanted to reinstall windows and clear everything. He had windows XP. He don't know a lot of computers, so I decided, I will do that. I took his HDD to home and connected to my computer. Installation of windows XP started and everything worked well.
But when I bring HDD back to his computer and connected it, all I get after start computer is that (picture bellow). It is something like cursor, flashing on screen and never end. Does someone know, what could went wrong, when that worked well in my PC and its same windows, which he had before? (Sorry for bad english)
Windows is configured based on the hardware underneath. Installing windows in one system and then placing the HDD in another usually does not work. Use a Bootable USB to install Windows in the system as the DVD Drive isn't functional.

How could I switch off primary Macbook screen?
I'm working with 2 External via Thunderbolt and HDMI on new Retina Macbook.
I want to switch off retina display and work just with external monitors without closing the cover of my laptop. Is there any setup option for that? I didn't find it under Preferences.
It seems to be possible to sleep display so by I/O Kit:
http://explanatorygap.net/2009/01/31/a-screensaver-to-send-your-display-to-sleep/
But I am not sure whether it can control single monitors.
you are searching for the 'clamshell' mode. the only way i get this to work is to wake my mac with external keyboard while the lid stays closed
see: http://support.apple.com/kb/ht3131
This worked like a charm on my old macbook (late 2008) with opening the lid again and the screen stays off until 'force' detecting it...
however, my retina display also wakes when in clamshell and then being opened.
There is a reason to this: Heat.
Aluminium macbooks can get really hot, especially since the vents are in the back and blowing the heat up in front of the opened display. Your retina macbook shuts itself down at about 110°C to 130°C, but please be careful.
