Please, help me!
I have a Lenovo Y580 laptop. I updated the BIOS by right of described here.
I have a backup about BIOS that I made with "fpt" program when my computer worked fine (it is about 4 Mb sized).
I tried to restore the original BIOS but it was a failure.
The laptop started with button Fn+B (the screen was dark), it beeped for 2 minutes than the fan rotated in maximum speed 2 hours long.
Than I shut down my laptop. After this I tried to switch on but it didn't start.
At the moment it doesn't respond to the Fn+B+POWER ON either. The fan doesn't rotate either, it doesn't show any sign of life.
How can I reload the old (original) BIOS?
I have the SPI EEPROM programmer, so if it needs to desolder and to program it's not a problem for me. I only need to know how I upload the BIOS file into the 2 qty (W25Q32 és W25Q16) EEPROM. I think of the partition of memory area.
Thank's!
