Hi Techies Need help

Actually 650g1 is working one, where i removed the cmos battery it is also behaving like that no display fan runs on high speed.

Any Help would be appreciated.

Try:

I just had the same issue, so I powered it off and then I pressed the power button and held it pressed for approximately 30s, then the laptop could boot fine again.
