Hello, I just posted on the Prema Mod blog, and just realized my misstake... I will kindly ask for my comment to be removed, as i feel right here on Techinferno is a better place for my question. I have a P150SM-A / GTX970M with stock BIOS. Had to shut it down to reboot, and when it turned back on, the BIOS kicked in in “recovery mode”. I pressed continue, and after some progress bars it rebooted. Now, it won’t turn on at all anymore: the fans are both ON, the keyboard is backlit solid blue, but that’s it. No screen backlight. I have tried numerous things that were asked here: Removed the battery, power plug and CMOS battery and let it sit for 10mn… Same thing. Tried to change RAM slots, but no cigar… Is there anything i can do before going to my reseller? I don’t have an external screen or rig to use unfortunatelly, and i would really appreciate any direction. Notes: - When the computer went into recovery mode, I noticed that the HDD identifiers were different, before they were P0, P3 and P5, but this time change to PM SM and SS (So primary master, secondary master and secondary slave… Reminds me of my first PC with IDE back in 1998). - Also, before doing this, the computer took an abnormal amount of time before showing me the BIOS (Like it was stuck on detecting some hardware). I also remember briefly seeing a message about an invalid EFI thing… Which is super weird as I dont use EFI. - When i turn the computer on, I noticed that Caps Lock / Num Lock are not functional. However, Fn + 1 puts the fans at full speed. Not sure if this information is of any help. - Im aware of the method to Fn + B to recover a bios, but I'm not too comfortable doing so, as it might break the warranty, yes? Thanks for your help!
