Cannot access BIOS on a Lenovo U410

Question

I'm adding the the Microsoft Enterprise Application Block's "Exception Handling" module to my project. Following thier instructions mnsd MSDN it says I need to add a using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling; statement. Does this need to go in every single file that throws an exception handled by the the block, or just the file that catches the error?

For example, say I've got FormMainView, FormMainPresenter, and Class1, Class2, Class3. FormMainView is the view that calls FormMainPresenter, and that delegates specific tasks to the three classes. Classes 1 -3 throw various exceptions and they're caught in the Presenter. Do all 4 files need this using statement, or just the presenter?

Using the MS EAB 4.1, by the way.

Solution

The default option for the U410 to enter the BIOS is Fn+F2 if it is in hotkey mode. If it is in legacy mode you need to use F2. Ubuntu should not change this at all. Have you tried doing a cold boot and hitting Fn+F2 or F2?

Note: You need to do this very early. If you see the Lenovo text logo, it's probably too late. Your best bet is to probably force restart (with OS) and, holding down Fn, keep tapping the F2 key.

Yes i tried a cold boot and both Fn+F2, and F2 however it does nothing and just boots the OS

In regards to your second paragraph, perhaps I misunderstand how the Exception Handling block works. Say I simply threw a File Not Found exception while using System.IO. That'd compile perfectly fine. Now say my Exception block had a policy for File Not Found exceptions... Wouldn't it still compile just fine, but not behave as I'd expect it to? Still in the process of configuring my App file and reading MSDN so I can't easily test it. I guess a better response is that it simply says "Use a Using statement instead of fully qualifiying it", so I wasn't sure where I'd be "addressing" the block
