在我们维修PC-1500计算机时,发现CE-150中充电电池损坏率较高,一旦充电电池损坏,单独使用外接电源时,CE-150也不能正常工作。为此我们对这部分电路做了如下改进: 改进此电路只用了3个元件。2×2微型拨动开
When we repaired the PC-1500 computer, we found that the rechargeable battery in the CE-150 has a high damage rate. When the rechargeable battery is damaged, the CE-150 does not work properly when the external power supply is used alone. To this end we made the following improvements to this part of the circuit: Improve this circuit only three components. 2 × 2 micro-dial to open
