The key to restoring electronics is taking prompt action to prevent further damage. Smoke residues can contain acids that will corrode metal surfaces when moisture is also present. If the residues are not removed, corrosion eats away at metals and causes electronic failure in the device. 

Your SERVPRO franchise professional is available to clean the interior of electronic items to stop further corrosion. They will qualify with the adjuster about sending the electronics to be cleaned/inspected by an electronics technician.

It is very important NOT to turn on electrical equipment that may have been damaged.
