for the past few weeks i've been exclusively using hibernation mode. its been good to me until yesterday after i hibernated on and off about 5 times. i finally got my first blue screen error.

i'd like to try Standby mode but i have a couple questions.

1. how reliable is standby mode when your computer is being moved around and thereby shaken?

2. are there heat issues if i put my tablet in stanby mode and carry it for extended periods of time in my tablet pouch? i have a waterfield bag, a padded pouch with no ventilation holes for the fan.

standby seems a good way to go considering the tablet barely uses any battery during standby, compared to my t42 which hogged alot of battery during standby. i want to make sure its reliable during movement though.

thanks

Hi,

I am currently using my tablet in most of my classes and really only put it into hibernation or turn it off at night. Stand by works perfectly fine. I have the tablet set so when I press the power button it goes into stand by or when I close the tablet. That works great for conserving battery life when your professor feels the need to ramble on about nothing.

However I have found that if I place the tablet into its case, which also has no ventilation holes, and then take it back out after it was in stand by the fan just kicks on a bit earlier then usual seeing as their was no place for the heat to go. I have experienced no problems in this aspect.

The tablet is still on when in standby, right? Only the monitor, hard drive are 'operating'?
Hibernate, is where the tablet 'saves' your current desktop and turns it off? (and restores it back when you want to?)

Which one is more convenient (which require least time to get out of?)
And which one conserves more battery power?

The HD, processor, etc. are off in both stand-by and hibernate. In stand-by mode, your RAM is frozen and the system shut off, so that when it resumes, you are right back where you left off. A small amount of power is diverted from the battery to power the RAM during stand-by, but other devices are powered down. In Hibernate mode, the contents of your RAM are saved to the hard drive, and then the system is powered off. This allows everything to power down, so that your battery doesn't get sucked away. The tradeoff is that it takes much longer to resume from hibernation.

Ok, cheers cromas. That makes sense now :)

so is it safe to shake and move your tablet around (in a backpack lets say) while its in standby? is RAM affected by movement like the hard drive is?

i tested putting my tablet in my pouch with no ventilation for about three hours in standby mode. there was no heat issues. my tablet "woke up" and the cpu temp was at 38 degrees,

RAM is "solid state," so it's not affected by movement. Shake all ya like.

I have just used the hibernation mode. I will try the standby mode and see how that works. I also eliminated the page file.

standby only uses about 5 percent of the battery if left in standby for 12 hours. that's not bad at all. i use standby almost all the time and only go into hiberate if i need to swap batteries. standby is much more stable to resume from than hibernate as well. there is almost no heat generated during standby... so don't worry about that.

An interesting note about shaking the machine when it's in standby -- the safety of this can depend on how the laptop determines when its lid is closed. For example, with Apple laptops, there's a magnetic reed inside the LCD casing; the reed bends and makes a circuit when the lid is closed, and that's how the laptop knows when it's closed. If you shake the laptop hard enough, the reed will come loose for a moment, breaking the circuit and waking the laptop.

I doubt that ThinkPads use this mechanism though, so there should be no problem.
