HDX 16 ( Hibernation problem )

Hi Everybody, As I beleive that some of you migh have HP HDX laptops, I would like to ask you for help as HP technical support is unable to help me. They want my laptop back for repair which I am very unheapy to do so.
I own HP HDX X16-1005EA Premium Notebook PC.

The problem is as follows:

Example: when hibernate the laptop. Then switch it back on with mains button and do not touch any key of button.
Within 2 minutes the laptop automaticaly hiberante !!!
This happens on both ( mains power supply and battery as well )
if I will touch any button or key during this 2 minutes period the lapptop would not hibernate untill it reaches the set time ( see bellow )
troubleshooting : I checked the time when the omputer is set to hibernate in advanced power settings and it is as follows:

hibernate after:
120 minutes on battery
1080 minutes plugged in

sleep after:
10 minutes on battery
25 munutes plugged in

I am curently using HP Recommeded power plan and if I switch to other plans ( Power Saver or High Performance ) it does not make any difference.

I also tried to set the hibernationand sleep to never but again no difference.

I also tried to use the recovery DVD to reinstal the operating system ( just in case this is caused by some virus ? ) but it does not make any difference !!!
The problem is still there altough the OS was re - installed so it can not be used by additional software, virus or so.
I am running latest BIOS version F31.A and regulary using HP update service to update all drivers etc.
setting changes : No nothing was added or changed.

Could you please check this on your laptops if this is normal ? I do not think so but I am not sure these days

thanks a lot for your help and reply.
Stan

 

Are you sure it's not the screen powering down?

 

Ohh yes I am 100% sure. This is because if it would be the screen which powering down I would not receive a message " Windows Resuming " at the beginning. It is definitely from hibernation. Do you have HDX at home ?

 

I had a similar problem but it would happen randomly. I sent it my laptop several times for repair and this last time they some how decided to replace my keyboard and that has seemed to fix my issues. So perhaps that might work for you too.
