PSP1000 battery is locked issue 20

I guess it's a battery problem, I suggest you change the battery. I guess no matter how much you torture that battery, nothing will come of it.

Because. Complete charging and discharging is carried out every time.

Let's get rid of the battery.

Lithium batteries are most overshot and overdischarged.

Let's change the battery.

Never drain the battery from the battery.

Try not to buy group electricity, the quality is not up to par, or the original electricity is good, you get what you pay for.

First of all, we have to determine if it is a problem with the machine, oh My machine has fallen before, and then the motherboard has been replaced. Something strange happened after using it for a while. It's the machine that will knock out the battery.

Everything is working normally, nothing is out of the ordinary. But sometimes the battery is knocked out when it is turned on again after standby. The battery is directly charged...

And the machine is not battery every time it is turned on again in standby. It's an occasional boot to play.。。 I didn't know it at first, but when I changed 3 pieces of raw electricity, I realized that it was a problem with the machine...

If the LZ rule is a problem with the machine, then the battery can only be replaced After the battery is locked, even if it is done, it is basically the same.

The power is displayed as- means that your battery is not working, PSP can't identify this battery, and it's not expensive to buy a battery Now, 2,30 yuan can buy a large-capacity assembled battery, above.

It is recommended that 20 30 do not buy, and if you want to change, you must change the original.

The assembly is absolutely unsafe.

To maintain the battery, it is necessary to fully charge and discharge it every time.

Solution to PSP power lock:

For the PSP3000, if the PSP3000 is powered off, you can perform the following operations:

1. Remove the battery and let it discharge, it is estimated that it will need to be placed for one or two months, discharge until there is no electricity, install the PSP, and turn on the power supply.

2. Remove the battery, use the electronic light in the lighter, and hit the positive and negative electrodes once or twice, which can be saved.

If it's a PSP1000 or PSP2000, the solution:

These two models are locked and generally unheard, but the PSP1000 can be repaired with Shendian.

Remove the battery and let it discharge, it is estimated that it will need to be placed for a month or two, discharge until there is no power and install the PSP, turn on the power supply, remove the battery, use the electronic ignition in the lighter, and hit the positive and negative electrodes once or twice, which can be saved. Lithium-ion batteries generally come with a management chip and a charge control chip, in which the management chip has a series of registers.

The specific reasons for the battery to be locked are mainly as follows: charging the PSP raw current with an assembly charger. Use a domestic brand charger to charge the PSP original current that is not within the specified range.

2.In some emergency situations, find a way to use a mobile phone charger (including"All-purpose charge") to charge the PSP battery.

3.I haven't used the battery for too long, and I haven't charged it before storage, not all storage will lock the battery, and there is a greater randomness, but charging it before storage will basically not lock the battery.

4.Moreover, the positive and negative poles of the 2000 original current are closed when they are locked, and they cannot output the current independently, and of course the PSP cannot be lit up.

In personal experience, there may be several reasons for this:

If the battery is generally locked, you don't need to connect any small bulbs to unlock it, just take it out and let it stand for 2 to 3 hours, and it will be automatically unlocked.

2.Find a DC power supply (the kind of transformer that is ordinary AC step-down rectification is the best, such as the charger of a toy car, the no-load output voltage does not exceed 10 volts (but cannot be less than 4 volts), the power is about 10 watts, and generally do not use a switching transformer, such as most mobile phone chargers) Disassemble the battery.

3.First measure the voltage of the cell, generally lower than the volt, and then use the positive pole of the transformer output to weld on the positive pole of the cell, and then connect the negative pole of the cell through the 500mA current file, and then connect to the negative pole of the cell, and measure the power supply current of the transformer, which should not be greater than 500mA and charge it for 30 seconds.

4.Then use the voltage gear to measure whether the voltage of the battery cell rises, and if it rises, continue to charge for about 1 minute (if the charging current is small, it can be charged for 2 minutes).

After that, measure the voltage of the cell, if it is above volts, then the battery cell can be successfully activated and can be directly put into the PSP to charge, after seeing that the charging has an indication and rises, the battery is fine, and then use 502 and other instant adhesive to glue the shell.

PSP has three output pins, except for the positive and negative poles (left and right sides), that is, a signal pin (middle), and the PSP has a signal pin during work or charging.

has been communicating with the host (everyone checks [battery information] in the boot state, and sees that [battery remaining time] will change, which is the result of communication).If in.

When charging and discharging, the battery signal foot can not receive effective signals (including all kinds of abnormal charging, discharging and storage), inside the battery.

The CPU will activate the protection circuit to lock the battery and cannot continue to output externally, which is"Lock up"Causes. After the locked raw electricity is installed in the machine.

There is no response when the button is pushed.
