Minibook out , black screen

My minibook N4100 does not start anymore. when starting the fan starts but I have a black screen. Impossible to boot on a USB flash drive, everything is blocked. No Chuwi logo. I completely turned off the machine and restarted it.

This problem occurs when I modified the operating system in Linux in the bios.

The BIOS is only needed when the device can’t be turned on.Can not be used casually, otherwise it is easy to become a useless brick.

Please contact

Does this mean that incorrect bios settings can make the minibook unusable?
If this is the case, it is incomprehensible, by changing the declaration of the operating system, I have never known such a thing.

Yes,BIOS cannot be used casually

This is the first time I have seen this.
What is the solution?

The bios should always remain accessible. I’m not flashing it, I just changed a setting.
This is the bios that you can use,try to flash it.You should contact if it is doesn’t work

nothing happens, it doesn’t boot on the USB stick.
I formatted the key on fat32 and past in the root all files

:disappointed_relieved: I’m sorry to hear that.Maybe is time to contact

I wrote to them, do you know if they’re responsive ?
Thank you

I have the same problem on a lapbook Pro. Also after a change in the BIOS. I wrote to a few days ago. THEY DO NOT ANSWER. The whole party should have a problem, measures must be taken.

Then please tell me your email.
