Re: Lenovo z50 70 bios boot

Hi Mozvatic,


Welcome to Lenovo Forums.


It could be a low CMOS battery, BIOS problem or many other things. Does this problem happen after a full shutdown, or just when the PC is in sleep/hibernate mode? Does it do this from battery power and mains power? Also, is the laptop still under warranty?


You could also try a "hard reset" for the PSU:


Note: To perform a hard reset, unplug the AC power adapter and remove the battery, and then press and hold down the Power button for about 6 seconds. This will drain any residual charge in the capacitors and reset the power management controls to their default condition.


Let us know how you get on.
