At Manhattan Computer Hospital, we're capable of fixing Macs, PC's, and more. When you bring in your Mac, PC, or Hard Drive, we will start by diagnosing the issue at hand (by running and testing every part of the computer and/or hard drive). Once we've diagnosed the issue, we will contact you about moving forward with repairs. Diagnosing an issue can take time, depending on what is wrong with the Mac/Computer, and how many steps it takes to figure that out. Moving Forward With Repairs. Once we've figured out the issue at hand, we will contact you about the cost to repair and estimated time of repairs. We know how important it is for you to get back your device with all of your saved files on it in a timely manner - so we take every step to insure that your device and its files will be protected. If we believe there may be a hard drive issue, we recommend allowing us to backup your files to an external hard drive of your choice before moving forward with repairs.
