One of my most famous article @ ReviewSaurus was “Use USB drive as RAM in Windows Vista“. However, I recently noticed that there are users who are experiencing problems of delayed resume time from hibernation or sleep state, when they enable the ReadyBoost feature.
Users have reported that it takes about 5-7 minutes for the computer to resume back from the hibernation or sleep state if the USB drive is plugged in but if they remove the USB drive then it resumes pretty fast. This has been reported mostly on Laptops.
Well, there is no actual explanation to this (as of now) but there are users who have reported the fix to this problem too. James Kendrick found the solution to this problem by editing couple of registry entries. Susan Bradley has mentioned various hot-fixes which will fix most of the problems related to Windows Vista at the time of resumption from sleep or hibernation mode.
On my laptop - even with a 2 GB RAM, (not USB), it takes seemingly ages for Vista to wake up from hibernation. But it is not much of a bother thesed days - I have gone the Ubuntu way. :)
@ Vyoma : It’s good that you switched to Ubuntu but I’ll say that its better if you can check the option of updating the Vista with the hotfixes which are mentioned in the Link provided in the post.
