the model number for my laptop is 15are05, and the serial number is PF29PQR5. The lenovo PN for my mobo is 5b20s44358. Sorry i didn't have that info on hand for my first post, I appreciate any help.

Hi! I'm having a very similar problem with the same model of laptop. Where can I find PLT_RST and how did you fix it?

Hi! I got a lenovo ideapad with an nm-c811 motherboard that would turn on (fan spin, hot cpu and keyboard light up) and presumably get to the bios, but there was no image on the screen. I tried flashing and verifying the bios posted in post #6, but the same problem persisted. I have a copy of the original bios, i only made one backup before i flashed, i should have done it twice.
I don't know what DMI is or what it has to do with the bios. do i have to modify the bios before flashing it to the laptop? please let me know....
