In “hibernation mode” the contents of the volatile memory (e.g., cache and system memory) are first stored to non volatile memory (e.g., a disk drive); and then, the entire system is effectively shut down. Here, typically, greater power savings are realized as compared to the sleep mode because the volatile memory units are shut down. However, it takes longer for the system to return from hibernation mode to its original, normal, active state because the “state” of the system software at the time hibernation mode was entered (as represented by the matter that was transferred from volatile to non volatile memory) needs to be “reloaded” back into volatile memory (e.g., by reading the state data from the disk drive and re-storing it back to its original locations in cache and system memory 103).
Unfortunately, during either sleep mode or hibernation mode, the utility of a mobile computing system is effectively non existent because the CPU (being shut down) lacks the ability to execute a variety of instructions. That is, useful software routines (such as email retrieval, downloading information from the internet, etc.) cannot be executed. Gas turbine engines and other axial flow turbomachines have rows of rotating blades contained within a generally cylindrical case. It is very desirable to minimize the leakage of the gas or other working fluid around the tips of the blades where they come close to the case. As has been known for some time, this leakage is minimized by blade and sealing systems in which the blade tips rub against a seal attached to the interior of the engine case. Generally, the blade tip is made to be harder and more abrasive than the seal; thus, the blade tips will cut into the seal during those parts of engine operation when they come into contact with each other.
In the earlier systems of the type just described the blade tip was a superalloy material, possibly even having a hard face, and the seal was a metal which had a suitable propensity for wear. For instance, porous powder metals were used. Now however, ceramic containing seals are finding favor, such as those shown in U.S. Pat. No. 3,975,165 to Elbert et al, U.S. Pat.

 In “ hibernation manner ” the contents of the volatile memory (for example, hoard and system memory) are first store to non volatile memory (e.g., a disk campaign); and then, the entire system is effectively shut down. Here, typically, greater ability savings are realized as compared to the rest mode because the volatile memory unit are shut down. However, it remove longer for the system to return from hibernation mode to its original, normal, active state because the “ state ” of the arrangement software at the time hibernation mode was entered (as represented by the matter that was transferred from volatile to non volatile memory) needs to be “ reloaded ” back into volatile memory (e.g., by reading the state data from the disk drive and re - store it back to its original locations in cache and organization memory 103). 
 Unfortunately, during either rest mood or hibernation mode, the utility of a mobile computing system is effectively non existent because the central processing unit (being shut down) lacks the ability to execute a variety of instructions. That is, useful software routines (such as email retrieval, downloading information from the internet, etc .) cannot be executed. accelerator turbine engines and early axile menstruation turbomachines have rows of rotating blade contained within a generally cylindrical case. It is very desirable to understate the leakage of the flatulence or other working fluid around the point of the blades where they occur close to the case. As has been know for some time, this escape is minimized by blade and sealing systems in which the sword tips rub against a seal attached to the department of the interior of the locomotive case. Generally, the blade point is made to be harder and more abrasive than the seal; thus, the sword tips will cut into the sealing wax during those parts of engine operation when they come into contact with each other.
