Users questions: On the morning of Day 2 useless computer can not boot the computer when the power supply has paste flavor apart and found a 2200uF * 10V and a capacitance of 1000uF * 10V ask drum and the machine under the people that can not be switched, though? Why capacitor drum?
Experts answer:2200UF 1000UF * 10V * 10V and +5 V power supply capacitors for filtering. When a bulge of them, generally have an internal breakdown, causing the power circuit. Due to short-circuit current is too large, resulting in power automatic protection, and therefore can not boot. The main reason causing the drum pack voltage is too high. Possible power 5V voltage regulator circuit is damaged, if the replacement capacitor is recommended to check 5V power supply circuits. In addition, to protect their computers from other hardware considerations, individuals proposed to replace a new power supply.
