倒平板的步骤过程
作者:yasden
本文介绍3款苹果老设备更换电池的方法,更换电池需要一定的动手能力,给iPhone 4更换电池很简单(每个人都能非常简单的操作),给iPod touch4更换电池有一些难度(需要电烙铁进行操作),给iPad mini4代平板电脑更换电池难度非常非常高(一不小心就会捅坏屏幕,除非很有经验,不然不建议自行更换,建议找维修的师傅进行付费更换),这三款设备更换电池的详细步骤请看下文。
一、iPhone 4 手机更换电池的步骤
某一天我打开抽屉,发现我的iPhone 4变成下面这样了,电池鼓包把后盖顶开了(看下图,下图不是我撬开的,是电池鼓包把后盖直接顶开,变成下图的样子):
于是在拼多多上买来一款iPhone4的电池,开始更换。
第一步:用螺丝刀拧开iPhone4手机底部的两颗螺丝(在拼多多买电池一般都会附送螺丝刀)。
第二步、两颗螺丝拧下来之后,将iPhone4 的后盖轻轻往上一推,就能把后盖取下来了(见下图):
第三步、用十字螺丝刀将下图红色圈出部位的螺丝拧下来
第四步、用指甲将电池接口扣出来(下图最下面的红色圈圈位置),之后将“Authorized Service Provider Only”那个标签撕开,就能把电池取出来了(如果电池粘的很紧的话,就用塑料片在电池下面慢慢撬,将电池撬出来)
电池取出来的样子:
比较一下原装的电池(下图右边)和国产电池(下图左边), 原装电池表面印着“美国苹果公司”的字样:
之后按照上面的步骤,反向操作,先将电池安装上去,再拧上螺丝,将后盖盖回去,拧上手机底部的两颗螺丝,就完成更换电池的操作了。下图手机旁边有个换电池的时候掉出来小零件,不用装回去也没问题的,想装回去也可以(见下图):
这样的话,iPhone4 的电池就恢复了青春了。
二、iPod touch 4代更换电池的步骤
第一步是用吹头发的吹风机,用热风加热iPod touch的屏幕四周2-3分钟,然后用吸盘在home键旁边拉开一条缝(见下图),再慢慢扩大缝隙范围,直到将home键这一头拉起来。如果拉不开,就继续加热,直到可以将屏幕拉开一条缝隙为止。
我没有用吹头发的吹风机加热,因为我的iPod touch电池膨胀,将屏幕直接顶开了一条很大的缝,因此只要清理屏幕四周的双面胶,就能把整个屏幕拉开了,从下图可以看出,电池膨胀把钢板都顶歪了。我也不知道电池膨胀将屏幕顶出来的过程中,是否有将硬件顶坏,我还是买了电池进行更换(买这款ipod touch4代的电池花了25元),要是更换电池之后,出现硬件问题,我也认了。反正死马当活马医了。
沿着home键往上拉,home键那一侧没有排线,在iPod touch的顶部有排线,所以要像下图这样把屏幕拉起来:
先将屏幕下方的钢板上的螺丝拧出来:
螺丝拧出来之后,屏幕下方的钢板就可以取出来了,记住每一个螺丝的位置(因为不同位置螺丝的长度不一样,所以要记住每一个螺丝的位置):
之后就可以看见鼓包的电池了(见下图),将下图红色圈圈位置的3个焊点用电烙铁加热,松开3个焊点:
也可以像下图一样,将屏幕下方的钢板靠在屏幕上面:
电烙铁加热松开3个焊点,这3个焊点我在下图用三个箭头标注了,方便大家查看:
下图显示已经松开焊点之后,排线取出的样子:
由于电池是用双面胶粘在底部的,所以最好用一个撬棒,将电池撬出来:
将电池慢慢撬起来:
取出电池的样子见下图,我在撬的过程中,将鼓包的电池撬漏气了,第一次闻鼓包电池里面泄漏的气味,有点臭:
新的电池买来是有一次性塑料膜包装的,拆开一次性的膜就无法退货了。
将新电池塞到原来的位置上,记得那个排线要从下面穿过去,绕到焊点上:
对准3个焊点,用电烙铁加热,将排线焊好,如果焊点比较难焊的话,可以加一点锡和松香来焊。3个焊点的位置见下图的3个红色箭头所指的方向。
焊好电池排线之后,将屏幕下方的钢板放回原位,拧上螺丝。下图红色圈圈位置的那个排线(有一个螺丝固定的,我已经把螺丝拧开了,我把这个排线叫做“螺丝排线”),可以用平头的镊子撕开这个螺丝排线(不撕开的话,旁边那根排线是几乎无法插回去的,因为没有操作的空间)。
只有将上图的“螺丝排线”撕开,下图红色圈圈位置的排线才能轻松的插回去。
将屏幕下方的钢板用螺丝固定好。只有“螺丝排线”撕开之后,屏幕和底部才能180度分开(见下图):
将下图手指位置的排线插好(只有螺丝排线撕开之后,才能用手指操作这跟排线,将这跟排线插回去,不然无法操作):
更换电池全部搞好之后,发现屏幕变成全白色了,变成全白色的屏幕了,估计是电池鼓起的过程中,把某些硬件设备顶坏了,因为电池上面的钢板都顶变形了。
三、iPad Mini 4代更换电池的步骤
买mini4代的电池,会附送很多拆机工具(见下图),另外需要一个吹头发的加热吹风机:
热风吹屏幕四周4-5分钟,直到屏幕很烫为止。
用吸盘把屏幕边缘拉开一条缝,用工具将缝隙固定,然后慢慢用刀片或者塑料卡片扩大屏幕四周的范围。
注意:塑料卡片或者刀片按照下图的方式插入屏幕四周,插入的长度不能插入超过1mm,插入超过1毫米有顶坏屏幕的风险。除非保证自己有100%把握,不然不建议自己更换iPad mini 4代的电池,因为弄坏屏幕的风险很大!
按照下图的方法慢慢扩大屏幕四周的缝隙,千万注意塑料卡片(或者刀片)插入的深度不能超过1毫米,不然有顶坏屏幕的风险!
屏幕四周很多双面胶,操作过程中非常容易顶坏屏幕,除非对自己有100%信心和把握,不然不建议自己更换ipad mini4代的电池!再三强调!
屏幕顶部下面有排线,所以按照下面的方式将屏幕拉开,从home键的地方拉起来:
屏幕顶部下面有4颗螺丝:
其中一颗螺丝靠近屏幕顶部,要将屏幕顶部像下图这样放,才能把这颗最顶部的螺丝拧下来:
尽量像下图一样,将屏幕放垂直(屏幕要往home键的位置拉一点,才能将屏幕放垂直):
将屏幕放垂直是为了取出下图最靠近屏幕顶部的螺丝:
四颗螺丝终于取出来了,用镊子将下图的这个小盖板取下来:
之后小盖板下面的一堆排线可以逐一的断开了:
断开一堆的排线后,屏幕才能分离出来:
之后用大的塑料板来撬电池:
慢慢撬,将旧电池撬出来:
换上新电池:
按照原来的方法,反正将所有东西安装回去即可。
我给大家示范一下,手贱又非要自己换电池的后果:
我撬屏幕的时候,把屏幕撬坏了:
留下了永久的屏幕损伤:
这个事情告诉我们,除非自己的手工技术很厉害,轻易不要自己更换mini4的电池!虽然屏幕撬坏了,投屏追剧、投屏给小朋友上网课还是没问题的,2016年买的mini4代,用到现在值了。
总结
三款苹果设备换电池的步骤我都写在文章里面了,如果手贱的话,有可能会损伤mini4的屏幕,建议找维修师傅来更换iPad mini4的电池。我的iPad mini4只从2016年购买之后,给小朋友上了差不多3-4年的网课,利用率极高,也算值回票价了。虽然自己手贱换电池把屏幕捅伤了,但经过几个月使用,我发现损坏的屏幕不会继续扩大,就这么将就用吧。
全文完,谢谢观看。

尉宗环2158倒平板是什么? -
萧陶农13855902311 ______ 把培养基倒过来, 培养. 防止培养液蒸发的附在上板的水蒸气倒流到培养液中. 所以要倒平板培养
尉宗环2158高中生物中 在选修部分有一个 微生物的培养 里面有一个倒平板操作 这是在制作培养基的时候进行的 -
萧陶农13855902311 ______ 两者不是一回事. 制作培养基的时候,倒平板:就是把熔化的培养基倒进培养皿里,让其自然冷却,就会凝固形成固体培养平板,用以接种.这个“倒平板”就是把液态培养基倒进培养皿里的意思. 进行培养的过程中也有倒平板:就是在接种完毕后,盖上盖子,然后把培养平板倒置放置.这个“倒平板”就是把培养平板翻过来放置(倒置)的意思.微生物的平板培养要倒置放置,这样可以防止杂菌污染.

萧陶农13855902311 ______ 复苏: 配制LB固体培养基,高压蒸汽灭菌,倒平板. 挑取菌种,在培养基上划线. 37℃培养24h至长出菌落. 摇菌 配制LB液体培养基.高压蒸汽灭菌. 无菌试管内加入3ml LB培养基,挑取单菌落加入培养基中,37℃,200rpm摇菌过夜. 扩大培养: 配制LB液体培养基.高压蒸汽灭菌. 三角瓶中加入50ml液体LB培养基,加入1ml菌液,37℃,200rpm摇菌至所需OD值. 注:培养基内需加入菌株所具有抗性的抗生素. 工具:超净工作台、酒精灯、接种针、试管、高压灭菌锅、培养皿等. 注意无菌操作.
尉宗环2158生物必修实验的一个问题:倒平板 -
萧陶农13855902311 ______ 因为培养基必须在热的状态下才是液态,才能倒入百平板中,等到培养基凝固后,温度降低,平皿盖上会形成冷凝水,如果不将平皿倒置,在操作过程中,皿盖上的冷凝水滴下,四处流动,就容易将污度染带到各个地方.而且滴落的冷凝水也会造成菌落被打散. 在培养的过程中,如果抗生素添加版不够,或者是其他原因,平皿里面是很容长出卫星菌落,或者是其他污染菌的,所以权不能认为灭过菌后,就没问题了,这其中操作手法,实验室洁净度都会影响的.所以一定要倒置.
