This is a
technique which is often useful for repairing both simple
mechanical devices and
expensive electronics. It involves very carefully using a sudden application of
force to the affected device/area. It is possible to do things from basic
repair to
complex reorganisation on the physical level.
Some people prefer to do this with the aid of
certain tools. My personal preference to use the
vertical descent variation. This allows you to apply the maximum effectiveness for for a minimum outlay of effort on certain items.
Warning: if used improperly, this technique may harm the resale value of the device
