Oddly, I also get the LED indicator for the trackpad lighting up at times when it's in it's "recovery flashing" state. I also get the pulsing of the fans as well as the power LED light (there's a pattern to the LED blinking. I confirmed that the issue isn't my GPU as it will push a splash screen on a P170HMx (it won't go further than that).
Enter sager bios how to#
I'm at a total loss of even how to debug this issue as the BIOS is corrupt, but I have no video when booting (GTX 970M), but can get the backlight to light on the LCD if I pull the 970M and put a 675M in it's place. I've done all of the troubleshooting I could possibly think of including a multitude of BIOS images for the P377SM-A and renaming then every convention I could possibly think of. Oddly enough, everything was smooth and had the v2 of Prema's P377SM-A image running for over a week before I reboot Windows (correctly) only to be met with these exact symptoms (they are to the T). If that doesn't change its FN+B behavior then you need to de-solder the BIOS chip and send it for re-programming (I may be able to help you with that). Remove the AC power, main Battery and BIOS battery and let it drain over night. Trying to boot with another CPU model may overwrite the messed up CPU values.ĮDIT: The system can not boot without CPU, but yes it may reset the BIOS values for the next boot, try it.Īt this point you could try to remove everything (SSD, wifi, one GPU) and only leave the CPU, one RAM stick and one GPU in there. Your system is unable to enter recovery mode.
