How do I remove the back cover of the HP 15ac13cl so that I can replace the hard drive?
I thought I had marked this issues as solved. Thank you so much to everyone that helped!! There were two hidden screws underneath the rubber pads near the monitor’s hinge. Once they were removed, it came right open.
HP has a link to their repair manual PDF here: http://h10032.www1.hp.com/ctg/Manual/c04… Looks like there’s a Service Door that may help.
