This bios.When I unplug the charger and plug it back in, it does not work at all, when I press the power button, an orange light flashes, or even when running from the battery.

If Builds doesn't work then try another BIOS and it's most likely not a bios problem
 
This bios ok but
Hello Sir
This bios Display ok , but when insert battery RTC not working normally,when i button of power led Amper lamp not work
This BIOS is OK, but when I install the CMOS battery and save the date and time and then turn the device off and on again, it does not work at all, only a yellow light when I press the power button, and when the CMOS battery is empty and I do not save the time and date, the device works great for me and I do not have the problem at all. Does the problem appear to be due to the BIOS programming, or is there a hardware defect?
