Comment 144 for bug 1239578

I just took it apart and tried it. Easy. On my 540p there are 2 service panels at the bottom 1 for HDD and memory the other smaller one is the wifi card. I already swapped the HDD with SSD by taking apart the larger one. Just make sure you get the Intel 7260 NGW form factor for the half-mini size pci slot. I'll probably even upgrade to the Dual band version for $30, even better!
