I remember when I first got paid, I wanted to buy a notebook that was light, durable and could be used for daily office work.

As a result, the two in one tablet notebook has become my first choice. But for now, I regret buying such a book, and it is precisely because of this that I deeply realize that cost performance does not exist.

But generally speaking, this book is good when I walk between work and home and need to work at any time. However, it did not suffer. After all, where does the price move you? Do you expect to have a good time?

On the evening of January 7, 2019, watching the blog of a technology leader, I subconsciously upset the bios and only modified a few irrelevant parameters. After restarting, I received a good gift: unable to boot.

Boot, black screen, stuck in front of bios, unable to access bios.

Contact customer service. Technicians are off duty during the Spring Festival. Turn left and right in the post bar, except for adding a few water groups, there is no substantial gain—— Perhaps the biggest harvest is to guide a Xinjiang fellow villager in the group to reinstall win10 on the tablet with micro PE.

The next day, I learned the following facts through various inquiries:

• This is a bios problem. The solution is simple. Reset it.
  • You can enter bios settings in the dark, Press F3 to restore the default, F4 Save to exit. (It's not realistic for me. On the one hand, I set the bios password, and on the other hand, this board does not supply power to USB. So where does a tablet get the ESC key to enter the bios?)
• I don't have a programmer. Of course, I don't have any bios firmware on the official website of Zhongbai, so I can't re brush the bios, nor can I blind brush through USB. (Xinjiang logistics is out of service. Even if we find the firmware, we can't buy the programmer, and we don't know the shortcut key for blind swiping.)
• The flat panel bios has no button battery. (This is the breakthrough point.)

It seems that there is no way except waiting for customer service to work. Even returning to the factory is the simplest way to deal with it. Therefore, I do not recommend anyone to buy a copycat board here, even though the configuration of this copycat can meet your needs.

After spending 20 oceans, the solution was found.

• The first step is to dismantle the machine.
• Step 2: Disconnect the connection line between the battery and the motherboard.
• The third step is to stand still for more than 10 minutes, and then assemble and start the machine. Done.

you 're right, The bios has no button battery because it is directly connected. Nine thousand milliampere batteries are not worried about the problem of power failure.

After the toss, start the machine, enter the system normally, and the task is completed.

After this toss, I summarized the following points:

• I recommend iPad and surface to purchase tablets. I don't recommend starting with Android tablets and Win10 tablets. Unless you dare to fool around, or it is convenient to return to the factory.
• It is not recommended to modify the (copycat) tablet bios settings anywhere unless you are sure to reset the bios. Of course, ordinary laptops do not recommend tossing about the bios settings, but it is still possible to set a password for the bios to prevent others from fooling in.
• If the bios is wrong and cannot be accessed to the bios and system, the simplest way is to unplug the battery and reset it. The desktop notebook can find the button battery, and the tablet can simply remove all the charged batteries.
• Finally, it is not recommended to buy Android tablets and win10 tablets from non large companies. Never buy cold products. You can't even find the struggling tutorials.
