Which laptop from these 3 should I buy for photo and video editing?

I must mention that I will use the laptop for casual full HD video editing and photo editing with Adobe Lightroom. So, in these conditions, which would be the best laptop for my needs, from these 3 options? All being at the same price, more or less.
1.) Lenovo G500 - #Display: 15,6" HD Led 1366*768; #Processor: Intel Core i7 3632QM; #Memory: 4GB DDR3 1600 MHz; #Video: Ati Radeon 8570M 1 gb + Intel 4000 HD; #Hard Disk 500 gb SATA.
2.) Lenovo L540 - #Display: 15,6" HD Led 1366*768; #Processor: Intel Core i5 4300M; #Memory: 4GB DDR3 1600 MHz; #Video: Intel HD 4600; #Hard Disk 128 gb SSD.
3.) HP ProBook 470 G1- #Display: 17.3" HD+ Led 1600*900; #Processor: Intel Core i5 4200M; #Memory: 4GB DDR3 1600 MHz; #Video: Ati Radeon 8750M 2 gb + Intel HD 4600; #Hard Disk 1tb SATA.

Yes, but the screen is the poorest from all (the poorest contrast), also the battery... If I would buy the Lenovo L540, can the processor be upgraded later? Which would be the limit?

Since you are using light video editing I would get the 3rd option as it has the most powerful gpu and has the best screen. Also it has the largest screen which can make a difference when video editing. I would though get more ram as 4 gigs may be the limit when video editing.

no the processor cannot be upgraded if the screen really bothers you than connect a hdmi from the tv to your laptop and use that,
