just followed some of the normal steps i could find on the internet.

 

there is a good youtube video about installing on the 7520.

 

just search online and on some of the normal forums, the computer runs great.

 

the only problems i have are:

 

1. Power Consumption (90 min on battery)

2. ATi 7730 won't work

3. Integrated Wifi card won't work (thinking of replacing it with a different internal card)

4, Sleep won't work

 

Can any one lend a hand?

i have the same laptop only i upgraded mine,

 

16GB ram

128GB Samsung 840 Pro SSD

removed cd rome and placed the 1TB hard disk there.

using an external wifi card.

 

I'm running os x 10.9 for the past month or so.

 

using mainly Graphic Applications such as Photoshop, Illustrator, InDesign and some video editing (Premiere,After Effect) and Appeture.

 

its running smoothly on the HD4000 though i would really like to get the ATI to work, the system recognises it but i can't really use it.

 

it has 2GB DDR5 which will benefit me a lot when i run complex stuff.

 

any one has a solution? i don't care about battery life since when ever i use it I'm connected to an outlet and if i would realy

want good power consumption i would just dual boot to win 8.

 

Any help would be much appreciated.

 

Thank You!
