Yoga 500-14 freeze and power button not working

2017-06-01, 10:18 AM

Hi everyone, 

It has been like 3months since my power button had stoped working so since that time i switch on my yoga 500 with the Novo button (right next to the power button) and it worked pretty well. But yesterday i wanted to dowload a software (to dim the blue light from the.screen) and I needed to restart the computer, I clicked on RESTART then (I had some windows open) but it froze sudenly. I couldnt do anything so I waited all night so that it could switch off by itself but this morning it s exactly the same: grey screen with the mouse but nothing is moving, the keys dont work either. I ,of course tried to press the Novo button as usual but it doesnt work and also I dont want to press it too long cause I dont want to reset my computer at all. 


Can you help me? 

Thanks in Advance

Hi, Victoule –


Thank you for writing in to the Lenovo Forum - happy to have you here today.


You can also start by flushing out all static, remove battery and AC adaptor and hold down power button for about 15 seconds.


Run a few tests from this link -



You should try Storage test, memory test, motherboard test, CPU test. Open Command prompt and try sfc /scannow to check if your windows files are corrupted.


Update us how it goes.
