A laptop can need its screen replaced for a variety of reasons. Dropped, kicked... drop-kicked. Regardless of what happened (or whether your laptop deserved it or not), we're not here to judge - we've seen it all.
Most of the time it is fairly straight forward to pull a broken screen and put a replacement in its place. While we're at it, we even check to make sure other hardware like the webcam and hinges still work.
Most of the time a standard, non-touchscreen laptop will cost an average of $150 (parts, labor and guarantee included)
Don't let that discourage you. We do touchscreens too! They just tend to cost slightly more and tend to take a little more time to get squared away. (Screen pun not intended)
