We fixed a Lenovo laptop that a customer brought today to our office. It was having problems during start up and it would not boot properly. We detected that the processor was overheating with nearly 90 degrees Celsius and the hard disk was at 48 degrees celsious. First we fixed the over heating problem cleaning the thick layer of dust on the heat sink and applying new thermal grease to the processor. Opening a laptop can be a difficult task, but we have the tools and experience to do it safely and quickly. Then we fixed the hard disk errors and the computer was fixed. Our customer was very happy he did not loose any data and we fixed the laptop on the same day.
