T61P battery discharge during hybernation

[SafeHarbor]

Hi, all,

My month-old T61P goes from full battery to 81% in 24 hours after I've selected Start -> Hibernate. This leads me to wonder if it really is going into hibernation.

I get this.

>powercfg /a
The following sleep states are available on this system: Standby (S3) Hibernate Hybrid Sleep
Standby (S1) The system firmware does not support this standby state.
Standby (S2) The system firmware does not support this standby state.

Can somebody else with a T61p running Vista (I have home prem) tell me if this is typical?

Click Start -> Hibernate and the screen immediately blanks and the sleep light starts flashing. After 7-8 seconds it stops and only the power good and plugged in lights remain. Unplug and all the lights go out.

Replug and press start. It shows the boot screen, then "Resuming Windows" with a wiper, then restarts quickly.

I thought I saw this once right after I got it, but I shrugged it off then. I've had need to use my old laptop for work recently so I've been using the R52. Then I'll pull the T61P out after it's sat for a couple of days, and the battery is at 43%.

Am I stuck in hybrid sleep mode when I select Hybernate?

Does Vista not show anything on the screen when it starts to hybernate?

Or am I barking up the wrong tree and this is really a battery issue? (I'll test that tonight by turning it OFF.)

turn off hybrid sleep so that it behaves like XP's hibernation. Hybrid sleep on Vista puts the system to Sleep/Standby and then after some time (i think a few hours) is when it actually goes and hibernates (like XP) So when you click hibernate it's actually going to standby first then hibernate if you really don't wake the system for a while.

So with that said tho, something must be stopping the system from hibernating. Some programs don't allow the system to properly hibernate. I also use vista but i disable hibernate since i just let my system sleep overnight till i wake it up the next morning. It only consumes about 3% of the battery power during that time.

Thanks. I turned off "[]Enable hybrid sleep" in the advanced power settings, and powercfg /a did not change nor did the behavior change.

What sort of programs would prevent this?

One thing you might try is go into your wired and wireless network adapter's properties (via device manager) and under the power management tab, uncheck "allow this device to wake the computer." (Or words to that effect.)

Also, in Vista, I think Windows Update is set by default to check for updates daily and to wake the computer to do so, so check for settings in WU to disable allowing windows update to wake the computer.

Thanks - I made those changes to the network adapters. Windows Update was set to go at 3:00 am... of course, it never has a net connection at 3:00 am.

Last night I turned it off, and had 100% battery late this morning.

Somehow I'm not seeing the wisdom of having hybrid sleep on a laptop. It may be great for folks that close it and open it back up an hour later and need a rapid resume, but for those of us that hibernate it and put it away for a day or two, it's a very bad idea. And, at a minimum, it's adding unnecessary cycles to the battery.

And the answer is . . . Kaspersky Antivirus. I set it check once per day at 10 am, and it made it through the night with 100% battery.

Thanks, guys, for the help and suggestions!

Glad you got it figured out. Once these niggling configuration issues are resolved, Vista is pretty much a joy, imo, of course.

Actually, I've on my second Vista media center main PC and have this ThinkPad now. I'm not one to bash Vista - I like using it, the way it looks, and its stability. I had to learn to throw RAM at it, though.
