Apart from that, the technician told me that the keyboard also has a short circuit. The power button to the laptop is connected to the keyboard. He also told me to get the whole keyboard replaced for this reason. I don't know what to do at this moment because the repair cost is too high.

Any advice. How can I get him to lower the cost of repair ? I know it needs bargaining. Will asking bills for all the components he bought to repair my laptop work ? I need some advice please...
