I've been to these guys on three separate occasions with different laptops over the years…read more. The first time, they helped me out for free. They found a quick and easy solution, fixed it on the spot and I was up and running in no time. The second time, they worked quickly, made the process painless, and charged exactly what they quoted. My laptop was ready for pick-up in less than 24 hours. The third time, they found more wrong than their initial estimate, but honored that original estimate, even though they could have charged me at least $150 more. They're friendly, knowledgeable, and more than willing to go above and beyond to make you happy. I highly recommend them.

"DID YOU SEARCH FOR COMPUTER REPAIR NEAR ME? CALL CPB FIRST - YOU'LL BE GLAD YOU DID!"…read more I'm glad I did. My Surface Pro could not connect to the internet all of a sudden. I did everything I knew to do (reboot router, modem, computer, on- board diagnostics, etc.) all to no avail. Saw CPB listed on yelp and gave them a call. After describing the problem to Becky, she suggested I bring it in for diagnostics. Got a call the next day from Eytan who said that probably due to a firmware update on the internal Wi-Fi adapter, it was no longer compatible to my wireless router. He disabled the adapter and inserted a USB wi-fi adapter and voila! Back in business. Quick and reasonable. These folks are knowledgeable, helpful, efficient, and friendly. What else do you need?

Bottom line: Scott has been knowledgeable, honest, and quick to serve -- like having an IT department at home. We've found that the best referrals are word-of-mouth, from friend to friend. And that's how we found CompuSmile. Hope you turn to this small operation (not a big shop) when you need help.
