Windows 7 Hibernation problem

Tyharo
I've noticed a recurring issue with my laptop when it comes out of hibernation and I login. Once I log in after coming out of hibernation, my computer will act slow; Google chrome wont open, applications stop responding and even restarting is slow. If I restart my system runs great and there are no issues to be found. My system is clean of malware and viruses and I have a paid license for Advanced System Care Pro so its not viruses and my laptop is defragged, disk checked and am registry error free. Any idea what could be causing this issue?

    But something is actually running so do you have the Task Manager open to see what the CPU and so on are actually doing?

    As for Advanced System Care it's OK but I wouldn't use that to believe that there are no Registry Errors just that it isn't bright enough to find them, but then again I don't really trust any Registry Tools all that much either. When you install Software it causes issues with the Registry and that is just a fact of life with Windows.

    What I really think is happening here is some software that you have installed is taking a lot of System resources and running whatever it does when the system comes out of Hibernation. It's a fairly common issue with Windows and is nothing new but very galling to actually find.

    Hibernation works (or doesn't in most cases) depending on your machine.
    When hibernation is enabled, the system creates a file on the root of the C: drive called hiber.sys This file should be equal in size to the amount of RAM the system has. So, for example, if you have 4 GB of RAM on your system, the hiber.sys file will be of equal (sometimes greater) value.
    That being said. When you wake your system from hibernate, you are accessing and opening up a 4GB file which contains instructions from the system as to it's state before hibernating.
    In a laptop environment, where a battery is involved, the state differs. Laptops generally go into power saving mode before going into hibernate. Your network or multimedia may be shut off in order to conserve battery life (depends on power settings). Your processor might slow down (dimishing the voltage through the system) in order to conserve battery life. This will be true, even if the power cord is plugged in. The amount of time before this occurs will differ however depending on how you have configured the device.
    All those factors have a direct effect on the hibernation or coming out of state of your machine. Furthermore, laptops generally have a 5400 RPM hard drive. 75% of the read/write performance of a regular 3.5" 7200 RPM drive. This means, that it takes longer for a laptop (generally speaking) to come out of hibernate. It takes longer for the system to read and process all of the information stored in the hiber.sys file.
    Continue to factor in, most laptops have a single hard drive. That hard drive also has a pagefile.sys file. This can be set to a larger number, but is generally also the size of the quantity of RAM in the machine. So, in this example another 4 GB file. This is your "swap space" for moving data between RAM and system and allowing to artificially inflate the quantity of memory a system can theoretically store.
    Once a system comes out of hibernate, it begins to re-initialize the powered down peripherals. This takes time. It than continues to load the state of the system.

    I could keep on going. But I hope this helps you nuderstand why the system seems "sluggish" upon waking.

    One last consideration to take note of... Nework connections. When re-awaking from hibernate, the network takes a few moments to re-initialize. In the meantime, any open network connections, etc. will generally cause explorer, for lack of a better term, bug out. Increasing the perception of sluggishness. The timeout for explorer to accept that the network connected drives, peripherals, etc. are no longer available is about 1 minute.

    When my laptop comes out of hibernating or sleep mode it doesn't ask me for the password and the system is config for it to ask for one.

    You might get better responses to your question if you post it as a new question rather than tacking it on to an old one, that may or may not be related. For now, you may need to look at how you have your laptop setup to enter sleep/hibernation. If it's set to save user credentials, then it won't ask for them upon "awakening".

    This is usually caused by a corrupt hibernation.sys file; for whatever reason, bad disk cluster, incorrect hibernation/awake, etc, etc.

    The easiest way to attempt to resolve this, is to remove this from your system, and then let Windows recreate it. To do so, try the following:

    Press 'Windows Key + R', this will bring up the ''Run...' dialogue.
    Type: cmd and hit enter.
    Type: powercfg -h OFF and hit enter
    Reboot your computer
    Again, Press 'Windows Key + R', this will bring up the ''Run...' dialogue.
    Type: cmd and hit enter.
    Type: powercfg -h ON and hit enter
    Reboot your computer
    Windows will now rebuild the hibernation.sys file.

    Hope that helps! ;-)
