Windows 7 64-bit and 3GB hibernation file?

[basketb]

Probably the stupidest question I have posted on this forum so far, but why is the size of my hibernation file in Windows 7 64-bit only 3GB when my T61p has 4GB of RAM?

Could it be because of Hybrid Sleep

I'd love to see the answer for this.

It's about the same size in Vista

i had a 1.95GB hibernation file..and when i tried to remove it thru disk cleanup it dosent happen..

why do you think so!?

Have you disabled hibernation? If not, why would you want to remove that file?

My guess is that Windows 7 bases the hibernation file on only the memory actively being used. Maybe only 3 GB contained data?

About removing the hibernation file using the Disk Cleanup tool, maybe you need need to deactivate hibernation first. Start an elevated command prompt (start, all programs, accessories, right-click Command Prompt, select "Run as Administrator") and type in

powercfg /hibernate off

exit

Then try the cleanup tool again and select the hibernation file. See if it'll get deleted.

On my ThinkPad with 1 GB of RAM the hibernation file is a little over 0.7 GB. A possible reason is that Windows may compress the content of RAM when writing it to the hibernation file. Linux does this.

hmm i did what

said and i did remove the hibernation file..

well the thing is that my HDD is 100GB and i have made a 30% partition for my primary OS which i keep changing regularly
and i have made another partition for my docs and stuff..so i guess i have to be a little considerate in the disk space in my C: drive!!

I believe his point was that maybe you cannot remove the hibernation file if you haven´t disabled hibernation before. That must be something different from Vista I guess.

yeh now that you have mentioned, back when i was using vista ultimate x64 i remember faintly that i deleted a similar hibernation file..am i right or is it my childhood memories playing with me again!?

[Marin85]

Probably In Vista you don´t have to disable hibernation (by some reg hacks or whatever) in order to be able to remove the hibernation file...

yeh i guess thats what i have done..still cant rem!? maybe its something with my new windows 7 craziness..
