Help With Registry Please

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

Although this is too simple a thing to miss out on..Check out if the Power Options properties contains the Hibernate Tab. You might have the Enable Hibernation checkbox unchecked. If the Hibernate Tab is not available, you are most likely having a driver incompatibility.Hibernate requires compatible drivers, but since you are upgrading from Win XP Home to Pro that shouldn't be the problem. You might still trying updating your drivers (The Graphics driver could be the most likely cause).Hibernation can also be disabled if you have more than 4 GB of RAM which is highly unlikely.By the way, I've never see the fourth hibernate button on the shutdown menu. The Hibernate button is overloaded into the stand by button. Holding down on the Shift key, toggles it to Hibernate (H being the accesskey). Another simple thing to miss out on.

The hibernation button is checked and I can but my machine into hibernation using keyboard shortcuts etc. but I deffinatly did have 4 buttons originally and yes i am able ot access it via the standby button. and no unfortunatly i'm not lucky enough to have 4GB of ram! Am i missing something in the registry? I wish i had looked at it before running the update to see what if anything has changed.

Ok I read the thread located at http://forums.xisto.com/topic/90033-topic/?findpost=1064346584 about the 4th Hibernate button update.

Here's what I feel has happened to your system. Being preloaded with XP Home, your Windows had the hotfix KB893056 installed (or Win XP Home has the fourth button feature embedded in it). When you upgraded to XP Pro, the hotfix might have failed to upgrade (or as per the second case, the hotfix didn't exist altogether). Check the Add/Remove Programs and make sure the hotfix is being shown as installed. If not contact Microsoft for the hotfix at https://support.microsoft.com/contactus/?ws=support

Microsoft states:-

When you click ?Turn Off Computer? on the Start menu, the Hibernate button does not appear in Windows XP Service Pack 2 or in Windows XP Tablet PC Edition 2005

I wonder if it means that the non SP2 versions of XP do have the fourth button. Either ways, installing the hotfix should be the solution.

Tried that out on my Windows XP Pro SP2 and it works. You need the hotfix and you have to create the correct registry key.

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System\Shutdown
Value Name: ShowHibernateButton
Type: REG_DWORD
Value: 1 (Hexadecimal)

Alternatively, you could use the registry imports that I exported just now to toggle the enabling and disabling. You can get them from this page on my site http://forums.xisto.com/no_longer_exists/
