Unable to Clear CMOS y740

2019-08-19, 1:07 AM

Does anyone know how to clear the Cmos completely back to factory on this laptop? I disabled HT, now I have a black screen... And of course tech support is utterly useless , and requests I send my laptop in for repair... For the love of God Lenovo, give your people some sort of training or info.

Unplug the power cable while your laptop is turned on, then press and hold the power button (force shutdown) until your laptop shuts down, don't release the power button yet, hold it for about 20-30 seconds more. Then release it, and then press it once, like your normally do when you power on your machine.

Pulling main battery, RTC battery, letting sit over night to drain. Holding power button until end of days does not work either.

Hello Friend,

I'm in the same situation on the Y730 model. Did you manage to solve?
