the issue began , in some day I plug HDMI cable at the boot time . after while the beep come and some times is working fine but now it doesn't work at all.

I try it step by step but there is no luck .

Hold the D key and press the power button. Please confirm if the screen changes colors

nothing happen .

Hold the Fn key and press the power button. The system should start running a diagnostic test. Please let me know if it works.

again nothing happen .

it is continue beeping 

Hi Alex ,

could you please help me where I can buy new motherboard ?

Thanks 

Hi Nawaf_2 and Alex, I have exactly the same problem.  M14x boots up once in every ten attempts otherwise I get the dreaded continuous beep.  I spoke with tech support and they have told me I need a new motherboard but at over £300 and the laptop is less than 18 months old, I feel this is a bit steep... Do you have any other suggestions please?

Hi Nawaf_2,

I'm really not impressed that it will be over £400 to fix a hardware failure when my laptop is only 18 months old. Will try and find out what the motherboard is as I'd rather replace my own too and try and save some money. Will keep you posted, but if you find out the model number in the meantime, I'd be very grateful if you would share it.

Thanks

I received this information , they said this is the model for Alienware 14
