hp pavilion g6 touchpad and keybord seems to be locked

[memoryram]

Hi,
sometime (maybe 1/10) when i reboot my laptop the keyboard and the touchpad doesn't work, but if i plug an external keybord, the external keyboard works.

To fix it I reboot my laptop and everything work, but i would like to know where's the trouble ?

Thanks.
