==MDB 相关问题== | |||
===MDB板连到PC,PC上报错,"RS232无法识别到串口,报错已停产"=== | |||

==电池相关问题== | |||
* 电池不充电问题,If a terminal cannot be charged, please check the following: | |||
1. Test with a normal battery that is confirmed to be rechargeable | |||
2. Confirm that it is using a charger charged through DC Jack | |||
3. Confirm if the charging indicator light and charging symbol are displayed properly | |||
4. Confirm whether the battery voltage rises and the percentage of charging symbols increases after charging for a period of time | |||
5. Confirm if the battery connector is welded properly | |||
* 【问题1】 | |||
现象描述:关机状态插上电源后,会强制进入电池充电动画,但这个耗时较长(8-10s),进入动画之前按电源键是没有响应的 | |||
客户场景:这个体验很差,部分客户认为电源键坏掉了,会加重力气去按,导致按键损坏 | |||
建议:能否去除电池动画,默认自开机;或者其他更好的方案 | |||
*【问题2】 | |||
现象描述:电压低的情况(低于7v,大概率)或者电量计坏掉(极小概率),开机后终端有可能获取不到电量,终端默认显示50%。此时充放电不会导致电量增加或者减少(放电/充电 都一直显示50%),需要重启才能恢复正常 | |||
客户场景:客户不知道具体电量是多少,使用过程中有可能造成终端硬关机;此状态下,电量无法增加或减少,客户有可能会提出返修需求。 | |||
建议:建议不要默认显示50%,应该提示充电异常或者直接显示0%;或者其他更好的方案 | |||
*【问题3】 | |||
现象描述:电压低的情况(低于7v),开机进系统后终端电量显示0%,触发低于3%关机机制 | |||
客户场景:客户会反复开机,以为机器坏掉 | |||
建议:客户反馈PAX的机器,低于7V也能开机,而不会突然关机。会提示打印机不能用,需要进一步充电。 | |||
*【问题4】 | |||
现象描述:第一次插电池,电量会不准,需要充满或者放光,这是一个学习过程(If you replace the battery with a new one, in order to ensure the accuracy of the gauge (battery meter) display, please fully charge and discharge it once, and then confirm its discharge situation) | |||
客户场景:这种状态下会让客户产生误解,比如电量使用,掉电特别快 | |||
建议:是否有更好的方案 | |||
*【问题5】 | |||
现象描述:部分电池使用一段时间后,尤其是在寒冷地区,当电量低于30%时候,掉电特别块 | |||
客户问题:客户认为电池不耐用,而转用其他竞品 | |||
建议:是否有更好的算法,加强低电量体验 | |||
*【问题6】 | |||
现象描述:部分客户用的非5V2A的电源,比如PC电源(5V0.5A),这样会导致充电很慢 | |||
客户场景:插在收银机上充电 等非标配电源 | |||
建议:充电低电流告警? | |||
==移动网络相关问题== | |||

==串口取log相关问题== | |||
