This seems to be a common problem among those who posted a review. My laptop just wasn't charging and I was getting an error message on my screen. Anthony Russo helped me by experimenting with several cords he had and he concluded it was the box of my charger that was bad. Fortunately he had one that worked for my laptop. He was able to diagnose and give me a new cord in less than half hour for $30. I'm glad to finally get this fixed. Anthony Russo has a kind demeanor and easy to talk to. I highly recommend him with any computer problems you have. The business is located on the 2nd floor of the building and even though there is supposedly a garage nearby, I was able to find street parking and fed the meter (4 quarters for half hour).

I recently started a consulting firm and, for the first time in my career, I am relying on my…read morepersonal computer. Unfortunately, my computer began to slow down and became very unresponsive, which made me extremely anxious since I don't have an IT team to turn to. I found Acamar Computer Services on Yelp and decided to contact Evan based on his excellent reviews. Everything I read was accurate! After explaining the urgency of my situation, Evan was able to see me that afternoon. During the consultation, I mentioned that I was prepared to hear that I needed to buy a new computer, considering I had purchased mine in 2021. However, after just a few minutes, Evan informed me that my hardware was in good condition. He only needed to address the "software bloat" to get my computer back in order. He also assured me that once this was done, I would likely have another two years before needing to worry about replacing my computer. We spoke on a Friday, and he kindly asked if I needed my computer back over the weekend or if I was okay leaving it for him to start working on it the following Monday afternoon. I chose to wait until Monday so I could finish a few more tasks. I dropped off my computer on Monday evening and picked it up the next day. Evan took the time to explain in detail everything he had done and how each change improved my computer. Evan is extremely talented, efficient, and a pleasure to work with. His pricing is very competitive and well worth every dollar spent. His primary focus is on delivering exceptional customer service, which is exactly what Acamar provides. I informed Evan that he is now part of "The Chrysalys Team" and will be my go-to IT professional for all my computer needs moving forward. I cannot recommend Acamar highly enough. Evan is a lifesaver!

When we got the new power cord and it didn't work either, we quickly realized we needed help getting the files off the hard drive of the dead laptop. We hadn't had a chance to backup the files before it died. We put out a project request on Yelp and started looking for companies that could help us We found Fastball Computers and Scott Nelson. Scott responded to our phone call and project request and was able to see us the next day at his shop. We took our laptop and got to watch Scott take out the hard drive and connect it to his computer and then transfer our files to our external hard drive. Scott knows his stuff and explains things so you understand what he is doing. His price was incredibly reasonable for the work he did. We have new laptop for my wife and all her files and pictures and are able to move forward. If you need data recovery services or other computer services, don't hesitate to call Scott. It's nice to have a company near us when we need it.
