I updated my T540p a few days ago using Lenovo Solution centre, hiwever, it cant boot after update. The power button is on and fan spins, but the screen is black. I tried: remove battery and all external device and press power button for 30 seconds, out back the battery, still screen wont show anything; tried usb recovery stick, didn't work; tried Recovery discs from Lenovo, still failed.
Please help. Thanks in advance.
