Charles really knows his stuff; I haven't used this computer in a couple of years and it is better than it ever was. He helped me with donwloads that I needed, set up the operating system and was a wealth of inforlmation on a wide range of IT topics. He also set up a malware account for me. He is friendly, patient and was fun to talk with. I highly reccomend him! Thanks again Charles!

Thank you so much for the recommendation! I’m glad I could get your Windows 11 reinstallation done and back to you with same-day service. I know how important it is to have your PC up and running without the long wait, so it was a pleasure to help! If you ever need anything else, I'm always just a call or text away at (408) 660-3748. Best regards, Charles Lightning Computer RepairPosted onTrustindex verifies that the original source of the review is Google. Charles is the best. I initially contacted him a few years ago with a display problem, and he actually walked me through it on the phone, got it fixed, and he didn't charge me anything. It's rare to see that level of integrity and customer service these days. He's also done some hardware fixes for me , is very knowledgeable, very efficient, very personable, and very reasonable. This time, because I had some old software that I was very dependent on, I was very concerned about their compatibility upgrading to Windows 11, but he nicely upgraded my system to Windows 11, and ensured that those old programs worked, not only on the new Windows upgrade, but also on my Laptop, which I was having some compatibility issues on. I will not hesitate in the least to hire him for any of my computer issues.
Owner's reply
I’m so happy to hear those legacy programs are running smoothly on Windows 11! Maintaining integrity means the world to me, so I’m glad our first phone call a few years ago built that trust. It was a pleasure handling the hardware and software upgrades to ensure your specific setup works exactly how you need it. Thank you for the high praise and for continuing to trust me with your tech! I’m always here whenever you need a hand: (408) 660-3748. Best regards, Charles Lightning Computer RepairPosted onTrustindex verifies that the original source of the review is Google.

We truly appreciate the 5-star review and your trust in us here in San Jose. If you ever need any more tech assistance, we are always here at (408) 660-3748. Best regards, Charles - Lightning Computer RepairPosted onTrustindex verifies that the original source of the review is Google. The reviews of Charles and his company are true and valid. I had mishandled the installation of a new CPU, and knew I was far out of my comfort zone to try and resolve my self-induced issue. Charles was polite and understanding, not making me feel like an idiot. We had some preliminary discussions over the phone before I dropped off the desktop. Again, Charles provided a detailed game plan, and before I returned home, he diagnosed the issue and suggested a refurbished system, along with the estimated costs, which I felt were reasonable. Charles kept me informed throughout the day, and was able to complete the work by late afternoon. I now have a more powerful and upgraded system thanks to Charles. Would highly recommend his services.

Best regards, Charles Lightning Computer RepairPosted onTrustindex verifies that the original source of the review is Google. As everyone has said in reviews, Charles is terrific--super quick to respond, very knowledgeable, "lightning" quick turnaround, and very reasonably priced. Sadly, my computer is toast (thanks to two spills in quick succession--coffee and wine) but Charles was able to find/save the data off my hard disk I needed and then offered to recycle the parts that could still be used and recycled the rest. Would highly recommend him!
Owner's reply
It is always a bittersweet success when we can save the data from a "toasted" machine, but I am so glad I could get those important files back for you! Coffee and wine are a tough combination for any laptop, but I’m happy I could provide a "lightning" quick recovery of your hard drive. Being able to safely recycle the remaining parts is just another way I try to help out my neighbors here in San Jose. Thank you for the high recommendation and for noticing the effort I put into being responsive and reasonably priced!
