Will see a mobile phone after all first is what problem, by switch on the mobile phone key
Without any reaction, insert charger to also do not have reaction
Tear open machine receive on regulated power supply looks (it is indispensable that mobile phone maintenance reads electric current)
?
Electric current is normal, switched on the mobile phone
Can conclude the problem goes to go up in batteries basically.
Measure batteries voltage with avometer (normal can opening Electromechanical pool voltage should be 3.8V above)
2.7v is apparent, batteries " hungry " dead
Such circumstance, we will to it activation. Can activation with batteries commonly board, I do not abolish this interest, use small crocodilian clip directly, receive positive electrode redly, receive negative pole blackly
Power source voltage is moved to 4 o'clock a few bend over see electric current achieve 1A above can
In a few minutes...
Measured batteries voltage to achieve 3.9v (if be in,filled very long voltage as before short of 3.8v, so this batteries may be broken)
Buckle electrify pool to discharge a line, the attempt switchs on the mobile phone
OK, switched on the mobile phone

The mobile phone does not switch on the mobile phone, a lot of moment are batteries washed-up (or the mobile phone is long need not batteries short report is serious) bring about a mobile phone to cannot switch on the mobile phone, it is OK that such circumstances need to activation to batteries only.
If the mobile phone also appears not to switch on the mobile phone suddenly or the friend need not not switch on the mobile phone for long, start work might as well if capability is strong go be being operated according to my tutorial, many upkeep below the province!
