My laptop was operating very sluggish, unresponsive and generally very slow. Lightspeeds PC repair called a few hours after dropping off, informed me “laptop needs a good tuneup, cleaning”. Picked the laptop up the following day and let me tell you… this laptop has NEVER performed this quick even when brand new. Windows 10 now performing very well. No problems with this guy, he knows what he is doing without all the technical terms. His rates are more than reasonable. Highly recommend!
