BBK learning machine H2 does not display memory card after connection

You can first see if you can read the memory card on the learning machine, if not, it may be a problem with the card or you have not installed the memory card properly, shut down and reinstall it once.

If you can read the memory card on the learning machine, then there should be no problem, reconnect the computer to try, it is best to shut down and reinstall the memory card.

That's your learning machine's native (this machine is 2G memory, because in order to avoid users mistakenly deleting system programs, data caused by abnormal use of the small computer, the memory 2G is divided into two parts: hidden disk "hidden disk users can't see about 400m, used to place the system's programs and data files" and local disk "about about, users can store files freely").

There are the following reasons why your TF card is not reading:

1.If the gold finger or card slot is contaminated, it can be wiped with an eraser and it can be restored.

2.This is caused by the fact that you turn on the card or get on the card. You can plug in the card after shutting down If you try it a few times and it doesn't mean that your card is damaged, you can replace the TF card or go to the after-sales service to ask if it can be replaced or repaired.

3.Check that the TF is tightly pressed into the slot.

This is caused by the fact that you turn on the card or get on the card.

My method is: shut down (1-2 seconds after pressing the shutdown button and black screen is considered to be turned off) Go to the memory card, turn off the memory card after 3-4 seconds (note that it is not turned off after 1-2 seconds) on the card Turn on the power to see if there is a card Take the battery if you haven't yet, wait for 5-7 seconds to take the card on the battery Wait for 5 seconds to take the battery directly. Or wait about 1 second to get on the card and turn on the machine, if you try it a few times, you won't be on the after-sales service.

Complete!!!

You bought it online, or you just didn't buy a memory card.

There are several reasons for this:

1) The metal interface of the memory card is not in good contact. Gently wipe the interface with a dry, clean, non-static soft cloth or paper;

2) The partition format of the memory card is incorrect or the disk file is wrong. At this time, you need to take out the memory card, connect it to the computer with a card reader, and back up your important data to the computer. Then right-click the drive letter of the memory card, select Format, select FAT or FAT32 to format, and restore the data to the memory card after the formatting is completed.

3) The memory card capacity is too large;

4) The memory card is corrupted or using an inferior product. Poor quality memory cards have extremely poor compatibility and unstable data reads and writes, resulting in unrecognizable results. It is advisable to purchase a new memory card;

5) If you have changed multiple memory cards and cannot read them, it may be that the memory card interface is damaged. I can only take it to the after-sales service center for repair.

Is there any retrieval after plugging in the memory card? If it doesn't work after retrieval, it should be a problem with the card, or the card is not in good contact with the metal splice of the learning machine

There is no need to drive, you change the data cable or the computer to try, to determine whether it is the fault of the first class, if it is a machine failure, it is recommended to take the warranty card, hurry to the after-sales service to deal with it!

Are you sure you've run out of electricity? If you flush the electricity before you run out of electricity, it must flash for a while and it will be full! If it was something else, I wouldn't know, because I'd be able to flush normally. It is recommended that you go to the after-sales service and let the maintenance personnel check the machine for you!

It may be flushed, and there is still a little electricity in the data cable.

Hello 1If it still can't be recognized, please re-insert the TF card in the shutdown state, or insert and unplug the TF card in the banquet state, and click the reset button under the machine with a touch pen. 2.

Clean the metal piece of the TF card and try again?

The card is broken, it is recommended that you see if it can be formatted!

To see if there is a problem with poor contact, pry each of the metal shrapnel that connects the memory card to the device (if it is a card sleeve or change the card sleeve)! If the opinion is correct, remember to give it points!

1 You must make sure that your memory card is not set with a password in the phone, if you want to unlock the password of the phone, you are using the memory card.

2 You can clean the grooves first.

3 You can clean the metal pieces of the memory card.

It is recommended to go to the local *** to the consulting service in order to get a better solution.
