What should I do if my MP4 falls into the water it s all immersed ?

Don't worry, it's okay, I've been in the water and it's okay now, but yours should be clean water, it's okay, it's not the right way: because the flash drive is not charged, it won't short circuit when soaked in water, and it won't affect the use if it can be properly dehydrated. Some people use hair dryers to forcibly dry the flash drive, but this is not advisable because:

1.Although heating and drying can shorten the dehydration time, the damp circuit board base dries quickly due to external heating, and the internal moisture cannot be volatilized synchronously, at this time, due to the internal stress, the circuit board will be cracked and the circuit is damaged, so simple heating and drying is not advisable. 2.

There is no pre-treatment before drying. Although the flash drive will not be short-circuited after being soaked in water, when we dry or dry it, although the water evaporates, the salt and other impurities in the water are attached to the circuit board, which is often a good conductor of electricity, and the use of electricity will inevitably cause damage to the flash drive. Therefore, it is not enough to dry directly without pretreatment.

Correct method: Do not rush to dry the flash disk after it falls into the water, rinse it with clean running water to ensure that there is no sewage in the flash disk, and it is best to rinse it with anhydrous alcohol if possible. The sooner this is done, the better.

If the flash drive has not been disposed of in time and has been dried naturally, it is recommended to disassemble it, take out the circuit board, clean the board base with anhydrous alcohol and a soft brush, and then let the flash drive dry naturally.

It's impossible not to open, but if you're not sure, it's best not to fight, the second step I said depends on how clean your feet are hehe, just kidding, it's also a fact. You take the battery off, you can try to use the magnified rice I have seen before because the rice is more absorbent. You can also let it air dry naturally, and I don't think it's a big problem in trying MP4 is different from ordinary electronic products.

I put it under the pillow in January, the nanny washed the sheets for me, and directly brought *** into the sheets and threw it in the washing machine for more than ten minutes,,, found that my friend asked me to put it in the radiator, and put it for 24 hours, and when I turned it on again, it was just that the earphones were broken, and there was nothing wrong with it, and I am still using it! If digital things fall into the water, don't turn it on, that will burn the internal software, just let the water inside evaporate, no problem.

Go to the maintenance place and consult, don't turn it on.

1 All first, put aside the circuit, before falling into the water, the MP4 built-in lithium battery is electrified, after entering the water, it is equivalent to a direct short circuit of the positive and negative poles of the battery, and the protection board of the lithium battery starts the short-circuit protection mechanism, then the built-in lithium battery is now no output, even if your other circuit parts are fine, the moisture is completely dry, and it can no longer be turned on, unless the protection state of the lithium battery is lifted by charging.

Secondly, how long does the hair dryer blow for half a day? Thoroughly? Did you leave any water stains?

If there is any water stain, it must be removed with alcohol before powering on. There is also the water inlet machine to unplug as much as possible in the first time, stripping the battery. Your built-in words obviously can't be fast, and it's likely that you're unlucky to be unlucky with this built-in battery.

If the two stages of the built-in battery continue to supply power to the internal circuit board without first short-circuiting, and there is water on the circuit board, then burn the original product. In practice, many mobile phones fall into the water, if you can quickly remove the battery, there is still no major damage), it is best not to rush to power on, remove the battery after the circuit part is placed in a ventilated place, and try again in the sun for a few days. If you're in a hurry, it's easier to lose it.

This is no common sense, don't turn on the electrical appliance when it falls into the water, and wait until it dries to turn on, or it is easy to short circuit.
