I would like to replace the hard drive Acer one series. How do you get to the hard drive?

Hi if you look under the laptop you will see some panels with screws in, one has the wifi card , the other memory, and a big one that will have the hard drive under it, just unscrew it lift it off, locate the 2 screws for the hard drive and push it to the right to release it from the port, then lift out, remove the hard drive from its casing screws on the side, put your new hard drive in, and you are done...hope this helps
