By default, Windows 7 is configured to go in sleep mode whenever you close the lid on your laptop. While this is generally preferred by most users to preserve the laptop's battery life, it might be useful to disable this process. Many laptops provide the ability to connect an external display. In this case, closing the lid would also prevent any signal going to the external display. If you would like to stop Windows from shutting off your monitor when you close the lid, access the Windows Power Options component and disable this feature.
So try this, take a look at this KB.

This is normal, but it should only take less than a minute for your computer to readjust, make sure all your graphic card drivers are updated, for that may be a factor.

1600X900 is a higher resolution than that of 1280X1024. Therefore 1600X900 is a better resolution. If you would like to run at the lower resolution simply right click your desktop screen and click properties. Then on the settings tab use the slider bar to adjust the resolution. Lower to the left and higher to the right. If the desired resolution is unavailable then you could try downloading and installing the latest drivers for your graphics card installed in your computer.
Your card will either be AMD/ATI Radeon or Nvidia. You will need the model number of the graphics card, the latest drivers may increase resolution support for your card.
Also look on the bottom right hand side of your screen for an Nvidia Control Panel logo in green. Right click it and select the option to "change screen resolution" This may provide you with additional resolution options.
Take care!
