hello guys
i have a Lenovo x240, last year i tried to do a WIFI white list without knowing I flashed another bios to it, it didn't work I fleshed the original bios back it didn't work ether. I press power button, power led turns on and off. so a looked on internet tried many other bios files and one of them worked but with many problems
1. many times i turn it on and stay on black screen
2.if it turns on it takes 30 seconds to turn on
3. it doesn't wake up from sleep mode
I've attached the original bios if any one could fix it ill be very grateful
