old bios error what ?
We have replaced the keyboard on it and customer took it after 8 days came back and the laptop wouldnt show anything but you could hear fan spinning. After disassemble it and pull the battery out and replug everything in the light start blinking 7 times and 2 yellows then we try other bios but start flashing 1 time so wrong bios file after changing to another it start doing the same 7 blinks and 2 yellows
