I use a credit card to part the case. works very well

Zitat von mancunianlad:

As suggested above this is quite tricky due to the plastic catches towards the front of the case (ie where the trackpad is). Access the front 2 on the right by going in through the empty battery slot and prise away the plastic from the case. That leaves the 2 on the left which are tricky. Use a spudger or flat head screw driver (v careful here though so as not to scratch the casing) to work around the front left casing. Don't give up or despair - it does unlock eventually!
