The video card on my mid-2011 has died. Unfortunately I was one of the first one to buy a mid-2011, so I have now had it for 4 years and 4 months and Apple only extended that warranty to 4 years. So I am 4 months too late. As soon as it happened I removed the HDD and put it in a firewire enclosure and used it to boot my laptop. Works ok, just slower than normal. I found a new card online and it was delivered yesterday. I went to install it and I can not figure out how to remove the old card. In all the pictures I have found online it looks like there are T10 screws holding in the card, but on my computer, the screws look like the they are just round circles and nothing will remove them. I have not been able to find any walk throughs or tear-downs for doing this most likely because everyone else was able to get a free replacement and they are just now starting to get out of warranty. So any help to remove the old card and install the new one would much appreciated.
