MOTHERBOARD CARE

The motherboard design adopted by laptop manufacturers is extremely delicate and fragile and can be very easily damaged by heat and/or impact to the unit, light impact or moderate temperatures may affect system stability whereas serious impact or high temperatures may cause severe and irreparable failure of the laptop.

Repairing a laptop motherboard is a very complex, complicated process and can be both costly and time-consuming. Technicians usually use specialized machinery for welding the chips, replacing damaged chips, conductors or PCBs. If the motherboard cannot be repaired due to problems such as fracturing, burnt out or melted chips, the complete motherboard will have to be replaced. To test this, plug in the AC adaptor and check if the charging light is lit, if it is lit then the motherboard might be repairable, if not, the motherboard may be damaged beyond repair.
