I can confirm that the original problem still exists. A CPU frequency stuck at 0.77GHz when you wake up the machine on battery mode.

Thanks for what?

 

We are living with this problem since December 2013,

the new replacement laptop model is already out on the market.

Our chances are diminishing that Lenovo could solve the problem.

I just updated my Z510's BIOS to v39 and the problem of CPU getting stuck has been solved (atleast in my case).
Also, everyone here has been saying that their CPUs used to get stuck at 0.77 GHz though mine could not cross 0.75 GHz

Any updates on this issue? I have BIOS V39 installed and still experience this issue. Seems to be when I turn the computer on without it being plugged in.
