Thank you. I wrote the file you sent me onto the bios chip but it's not turning on. The white LED flashes 3 times and then nothing happens. When I press the power button again, another 3 white flashes. I tried writing the origianl bios file back onto the chip and the laptop turns on but asks for bios password. Am I doing something wrong here? Is there a something I've left out? Or does the TPM chip have something to do with it?
