Hi, right have read through the thread about the hibernation button, and this relates to that basically.but i need to ask you lot a question...I baught a laptop with XP home preloaded on it, an i had all four buttons right from the start. Great.However I have now upgraded it to XP Pro (using upgrade function) but now i have lost that all important fourth button (the hibernation one). I have looked through the registry and found the relevent subtree and it apears that i already have all the necassery components complete with ShowHibernateButton REG_DWORD. when i click modify on this the value is already set to 1 and hex is the ticked option. but despite all this i cannot see that button any ideas? If it helps there are also another REG_DWORD named HibernateAsDefault also with value set to 1, and the is a REG_SZ named (default) which under data has "(value not set)"please helpAlso i read somewhere about it being differnt for domain machines or something like that, I don't think mine is in a domain but i do have a wireless acces point network.gigglecream
