Hello!
I accidentally installed the BIOS from CoreBook X (i5-1235u) on my CoreBook 13 (i5-1235u). After installation, my laptop stopped turning on, only 2 LED indicators are lit - red and blue.
Please send the original BIOS for my laptop so that I can install it through the CH341 programmer.
Thanks!

If technical support is unable to send me a bios dump, then I hope for the help of users. Maybe it won’t be difficult for any of you to save the dump from your laptop :slight_smile:

Hello! We downloaded this bios to U0F1 flash memory 25R256JVEN. But the laptop still won’t turn on. What else can I try to do?

@manonegra222 could you see if this its hardware? or need to do anything else.

@Barni when you say it does not turn on, what do you mean exactly. You press the button but still screen does not show anything as if it has no battery?

When you press the power button on the laptop, 2 LED indicators (red and blue) light up. No startup occurs, the screen does not turn on, the keyboard backlight does not turn on, the processor cooling fan does not turn on.

In this case the computer is already with issues, and the warranty does not cover when the BIOS has been changed.
You need to send it to a professional repair organization and use a programmer to flash back to the factory BIOS.

I contacted a professional repair organization, and there, with the help of a programmer, they loaded the bios that you sent into the U0F1 25R256JVEN flash memory.(DN1E_BIOS_CHUWI_V107_Release_20230921A).
Loading the bios did not help, 2 LED indicators also light up and the laptop does not turn on.

Well, then it is hardware issues,maybe motherboard needs to be changed. Or it needs to be sent to repair to Hong Kong. Where are you located? But this repair will need to be payed by you :frowning:
