Lenovo Yoga 700 - I4SK beeps continously, won't turn on

I have a Yoga 700-IS4K. A few weeks ago, when I attempted to turn it on, the screen remained blank and it emitted a loud beeping noise which continued until I held down the power button to forcefully turn off the laptop.


The problem is exactly as described in this other forum post concerning the same laptop, the 700-IS4K.


There is also a YouTube video demonstrating this problem, again on precisely the same model.


Maddeningly, this doesn't happen all the time; sometimes the laptop starts up just fine. However, it's been happening more and more frequently and its clear that the laptop soon will not turn on at all. 


I have already tried re-seating and cleaning the electrical contacts on the RAM chip without success. I think it made the problem happen less frequently, but that could be my imagination.


Has anyone had this problem and been able to fix it successfully, or know what causes it? I hate to junk a laptop less than three years old (my other laptops have lasted over twice that long) and it's unlikely I'll buy or recommend Lenovo again if this turns out to be unsalvagable.

Hi jmcphers,


Welcome to the Community Forums.


If you still have warranty, then this should be reported to technical support so they can have full diagnostics on the machine.


To start with, best to do backup of yor files while there is still opportunity. BIOS beep code may relate to hardware issue such as internal power issue or ram failure. Diagnostics test like those offered with Lenovo Vantage and other softwares like MEMtest can help. Try comparing the results with other diagnostics like this and this.


Software diagnostics can similarly pass if the machine is currently working so further stress test may help trigger any possible positive results. Personally, I would try to swap another compatible memory stick and see if the same thing would happen.


Further isolation should be the key in searching probable points of failure.


I hope this elps answer your query.

Update us how things go.

Did you ever find the solution to this? I'm having the same issue and nothing I do seems to fix it. Mine won't turn on at all anymore.
