I am wondering if any ill effects occur if I shut my Thinkpad letting it go to standby, place it in computer bag and then after about an hour in another place, begin running it on battery letting it start in that place from standby?
Or, should I just shut down the laptop and then reboot? Thanks for your help.

In hibernate, the computer is actually powered off, so I would rather use that, because standby uses a little bit of battery; though one hour isn't really that long, if you have your computer set to hibernate after a certain period of time, the computer can actually come out of standby in your bag later on in order to hibernate.
-
just ensure that your laptop made a full shutdown before putting in the bag to prevent it from over heating.
-
These are odd responses. The OP asked if there are any ill effects from using standby. There aren't. Waking from sleep while being moved? That's a remote issue. You are more likely to get mugged than your laptop waking up while it is in your bag.
-
Standby is perfectly safe, and I use it all the time to transport my x200T.
I have NEVER had my ThinkPad wake from standby unexpectedly. I put it to sleep either with the Fn+F4 shortcut or simply closing the lid; and wake it by pressing the Fn key or simply opening the lid respectively.
In fact, I've even placed my laptop into a bag when it is still on for short trips. This is not recommended on a regular basis due to the risk of overheating in a tight bag (no place for the vented air to move).
Further, I prefer NOT to use hibernate or shutdown for short breaks (i.e. less than 2 hours). It takes several seconds (often one minute or more) to hibernate/resume or shutdown/boot. Conversely, standby occurs in less than 5 seconds each way. As such, the small amount of power (<1 watt) used by standby is less than the power used by a hibernate/resume or shutdown/boot cycle for relatively short periods.
Moral of the story - use standby and DON'T WORRY ABOUT IT. -
Thanks jonlumpkin for that. Helps a lot.

No, that's what standby is for.

I've done the same, although I do feel a bit leery about the laptop turning on in standby. My Thinkpad has never done that, although my old laptop has done that a number of times. Just be careful to make sure the moon icon does indeed turn on, indicating sleep - it's possible that an unresponding process on your computer could prevent your computer from entering standby in the first place.
In my experience, 24 hours of standby seems to use roughly 7 percent of a 9-cell battery. -
It takes me way more than seconds to wake up, the more times you hibernate the longer it takes vista to wake up for some reason. after four times it will take more than 2 minutes to finish loading. So I have to use standby sometimes I can't afford to wait that long when going into a class. It's despicable, 2.2 ghz, 3gb ddr3 ram, and it takes minutes to wake up. XP never had this problem on any computer.
OP, It only wakes up from standby because of the wifi issue. Turn the allow to wake up off and it will never wake up. Never. I do lose a bit of battery by keeping it on standby but that's normal. The hard drive is off so it is fine. -
Go to advanced power setttings, there are two options 'sleep after' and 'hibernate after', just make 'hibernate after' set to 'never', otherwise it will wake up.
-
I have seen hibernate do that sometimes. The pattern of occurrences is inconsistent though.
-
The time to hibernate probably depends of how much of the RAM is needed to write to the hard disk.
I'm not sure if it needs to write all 4GB to disk if you only have 60% used but 25% of that is cached. -
3GB of DDR3 is THE REASON IT TAKES SO LONG. Hibernate writes out the contents of RAM to disk when sleeping and has to read it back during a resume. Most laptop hard drives are between 50-70MB/s for writes and 60-80 MB/s for reads. As a result 50 seconds would be a low end (assuming a true sequential write/read).
XP "never had this problem" because it was usually equipped with far less RAM (often 512MB or less). RAM speeds and sizes have increased tremendously, but hard drive speeds have only improved by a very small amount.
In addition, Vista tends to use ALL of your installed RAM due to SuperFetch. This cached RAM is also written out in hibernate. Conversely, if XP was installed with >2GB of RAM it would often only use 512MB or less. Thus it could hibernate/resume faster.
In fact, I disabled hibernate on my x200 Tablet with SSD. Hibernate takes a fairly long time (4GB of RAM, 80 MB/s writes, 100 MB/s reads) and also consumes 4GB of my relatively limited disk space. Conversely, I can standy/resume in <5 seconds. Additionally, I can perform a full shutdown/restart cycle in less time than a hibernate/resume cycle (SSDs boot Windows quickly and the OS is usable immediately). -
What is the best way to disable hibernation in Vista and thanks.
Gary -
Guide.
Short Version:
- Open an administrative command prompt (open start, type "cmd", right click "Run as Administrator").
- Type "powercfg.exe -h off"
- Restart
- Verify that there is NOT a "hiberfil.sys" in the C: directory (you may have to show hidden/system files to verify this).
That's it. -
Thanks much for that.

To the Op:
It is perfectly fine to standby and leave it for an hour or so. Ive been told it uses ~1% battery while in standby per hour. Granted this depends on your system and such. But I use it all the time when Im not using hibernate.
I have been using hibernate in vista business for 1.5 years now(specs in sig) and have never had anything like this. I hibernate fully in ~30 seconds give or take 15 seconds and wake in the same time every time no matter what I have open. I usually have a good amount of applications open too. -
guys stop dissecting me it hurts
I guess I am at fault for using xp, osx, then comparing vista to os x. I disabled superfetch a long time ago. I must use hibernate because of my daily travelling patterns. If your solution is to remove RAM from the computer to speed up hibernate, I will sadly consider it. The progression of technology and small resources used by xp is rather irrelevant to me. Make an operating system that is faster than the last one. I sit and wait for vista to wake up while the osx sitting next to me has already booted up. or xp. or ubuntu. I guess I should consider changing operating systems completely. But that does not solve my problems with vista on perfectly capable hardware.
