What is the model number of your laptop? Are you using acpi? Without the model number, I can roughly guess that this is either a video driver and/or config issue; Could you also provide us the output of the following commands?
Code:

uname -a
lspci -k

If you can, please use code tags, thanks!

thank you very much for your help
it is probably a driver issue as when i do

modprobe nvidia

well the nvidia 302 driver is very old
the current nvidia kmod for el6 is the 310

for red hat enterprise linux 6.4 ( the current )
yum should show 310 ( if you installed elrepo )
with the elrepo installed ( it has the nvidia kmod )
Code:

yum search nvidia
---- from the list install the current --
yum install kmod-nvidia

and that will grab the required rpms that it needs

you will also need to blacklist the opensource " nouveau" driver and rebuild the boot image without the nouveau driver

search red hat knowlage base for the instructions
this is RHEL6 so you do have the required and paid for support contract
https://access.redhat.com/search/quick

you will need to login to red hat with the credentials you set up when you bought the required support contract
