Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

What does the screen show - anything?

Just bought the Mac Book Pro 17" - set up all OK but the applications are only showing on a small screen size, not full screen - the background is still visible as a margin - how do I take the view to full screen corner to corner so to speak.

Just bought the Mac Book Pro for my photography - set up and running last night, but the user screens ie Hot Mail, safari etc.. are only half size sat on the background - I have exhausted the help and calibration log...surel this must be simple to fix...any help out there..thanks..Paul.

Have you just moved over from WIndows?
This is standard on Macs. The ability to see more than one window at a time. Some apps - like iPhoto, Aperture etc - have a Full Screen mode. Check out the View menu.
Drag the lower right hand corner to resize the window.

downloaded acrobat reader 11 onto my Mac Book Pro, it can open the file but will not print. Get a message that says PDF cannot be printed, however, I forwarded it to someone else and they could print it, no problem. I called HP and spent an 1hour with them and then called Apple support and worked with them for 3 hours. No one can figure it out. Is there something wrong with this version? the pdf was created in 2004. Do I have to pay to get Acrobat?

Let me give you a slightly different perspective than everyone else here. You are using an unsecured wireless network, which means that all your network traffic is easily available for viewing by anyone else using that network. That's bad. Very bad, for you, unless you absolutely trust everyone who lives within range of this network. So stop doing it.
As to the Mac not connecting, wireless networking is simply too complex for any reasonable answer without more information. There are many possible error points, and as often as not it's the Mac that can connect and the Windows PC that cannot. Since you can't give us any information about the configuration of the neighbor's network, and can't make any changes to it, we can't do much to help you troubleshoot it.

After migrating a new Mac Book Pro from Time Capsule, I noticed that I lost a group of Favorites on the older iMac. The puzzling thing is that the Favorites are on my iPhone--not the old iMac or the new Mac Book Pro. How do I get the Favorites back?

If you are syncing using iCloud, try going to System Preferences/iCloud (computers) and checking Safari. If it is checked, try deselecting it, wait 10-15 seconds, and then check it again.

I have a new mac book pro which i use in england but I need to use German charachters frequently, is there a way of having both visable on the keyboard?

I have a new mac book pro which i use in england but I need to use German charachters frequently, is there a way of having both visable on the keyboard?
For example so that I can just press shift or another key to get the German character.

Some may already exist, but you will have to learn them. On my old system these can be found through keyviewer.app For example, if I press option+s I get ß Umlaut is a bit cumbersome as option+u then the actual letter. It may be possible to bind a key to do this function, possibly through System Preferences > Keyboard > Shortcuts
I have old, old references for utilities that let you rebind keys to other functions, and you would have to see if they have modern equivalents.
Ukelele Mac OS X Keyboard Layout Editor - http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=ukelele - mostly useful for character, not function mapping.

I cannot retrieve my emails on my Mac Book Pro operating on 10.7.3 Icloud was already workingit keeps asking for password and when i put correct password in it keeps asking for it again and again. This has just started today

I cannot retrieve my emails on my Mac Book Pro operating on 10.7.3 Icloud was already workingit keeps asking for password and when i put correct password in it keeps asking for it again and again. This has just started today

Though it's unlikely to be wrong if things were set up properly in the first place, as a check go to Mail Preferences>Accounts and check that the server setting for IMAP (incoming) is imap.mail.me.com (not just mail.me.com).
Your next step either way would be to go to System Preferences>iCloud and sign out, then sign back in again. (You can ignore warnings about data disappearing - your calendars etc. will disappear when you sign out but reappear when you sign back in).

The Basic Troubleshooting Steps are:
Restart.. Reset.. Restore from Backup.. Restore as New...
Try a Reset of the Phone... You will Not Lose Any Data...
Turn the Phone Off... ( if it isn’t already )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
The Apple logo will Appear and then Disappear...
Usually takes about 15 - 20 Seconds...
Release the Buttons...
Turn the Phone On...
If that does not help... See Here:

Mac Book pro 13 A1278 late 2009 boot but no screen

Mac Book Pro 13 late 2009, boot on 10.5.8 fine but there is no screen light, just black, webcam work fine. When I plung a external screen it is working fine, i have the desktop and so.
Why ? I pulled off the motherboard after a water (tap) splash. At this time the key board was crazy. I unplunged the video cable of course. I cleaned and reinstalled every thing. So now the Key board works fine except for two keys at left hand ; ALT AND CTRL but no screen. The water came directly on the video cable area and the cable have a fiber cover. I cleaned with contact cleaner. But nothing to do. Curiusly the monitor Pref seems detect the computer screen because it is list in the menu Icon on the finder.
I looked on internet It seems to by a lot of video cable to sell. It is because there are fragile ?

Either you display or the connection to the display is damaged. For a definitive assessment, take it to an Apple store genius bar for a free evaluation.
Ciao.
