Sleep mode

I could not turn my t61p on after I put it into sleep mode yesterday. I had to shut it down by holding down power button.

Well, I tried to figure why that happened and turned out that every time after I press fn+f4 and close the lid right after that computer hangs and I think it never actually gets to the sleep mode (only 3 icons are illuminated: battery, AC adapter and "Z") On the other hand, everything works fine if I press fn+f4, wait until it gets into the sleep mode and only after that close the lid.

Is there any solution to that problem?

btw, I'm using Vista Ultimate 32 and "Lid closed" option is set to "Do Nothing"

heh, I know, but there shouldn't be such a problem, should there?

I have had similar problems with my new R61i running Vista Home Premium. I am pretty sure it worked perfectly a couple weeks ago when I started setting up the machine, but I finally ended up recovering all the way to factory settings in order to get rid of OneNote and the Office 2007 preview that were installed and couldn't be uninstalled. Since then sleep just doesn't work. Thought I had it yesterday with installation of power management and drivers, but after a few hours it got messed up again. I would really really love to be able to get this resolved and settle down to enjoying the machine....

I think its 100% related to vista. I'm giving up on sleep when I travel. At home I use sleep if i'm going from room to room, but when i put my T61 in my bag, I just shut it down.

I've had it wake up during travel before after sleep

Have you guys tried hibernation at all?

Perhaps a stupid question, but what is the advantage of using sleep mode over hibernate? And if you are not using hibernate - do you disable it so it won't slow down the computer when working?

b/c sleep is much quicker than hibernating...hibernating takes forever in vista...it is esentially the same thing..but it doesn't write to disk and powers everything down except for ram using minimal power..a los of 10% batt life over 24 hours

Thanks. If I understand it correctly it will not have any impact on the performance of the computer when working on it.

Trying not to be too hasty here, but for the last 36 hours or so I have been able to use sleep/resume effectively (R61i, Vista Home Premium). It seems that if I am running with a wired ethernet connection I can put it to sleep but it will never resume. If I am running with a wireless connection sleep/resume works fine.

Don't know if this will help anyone else but it may be worth a try...

I've had the same problem with T61. It was kinda driving me crazy because I couldn't figure out why it would work sometimes but not others. But after reading this I think it may be related to closing the lid as well. Nice to know I'm not alone.

dpotter · #11 Post by **dpotter** » Tue Oct 16, 2007 11:47 am

Seems to be a pervasive problem with Vista. Not universal, but very common and not limited to thinkpads, let alone any specific Thinkpad model or series... But no, you're far from alone!

I continue to have no problem so long as I am using a wireless network connection instead of a wired one...

Sleep! It is a blessed thing...

ran007 · #12 Post by **ran007** » Thu Oct 18, 2007 12:14 pm

I'm using Server 2003 Standard on a T61, and I get a similar problem. 1 out of every 10 or 15 Fn F3, I'm unable to make the screen turn back on. However, if I close the lid, wait for the sleep beep again, then open back up, it works....

strange.

AlexanderT · #13 Post by **AlexanderT** » Sat Oct 20, 2007 3:51 pm

I have been having the same problems with my T61p running Vista Ultimate. In 9 out of 10 cases, resume works properly. But occasionally it get stuck, and only holding down power button helps me out there. Unless Lenovo or MS is going to fix this issue, make sure to always save your important data (e.g. documents) before going into sleep mode!

alphawolf · #14 Post by **alphawolf** » Thu Nov 29, 2007 10:28 am

Why do you hit fn+f4 anyway unless you plan on keeping the lid open? Why not set your laptop to sleep when you close the lid (a default in XP I believe anyway)?

Sleep and hibernate are NOT essentially the same. Sleep powers down anything that's mechanical (HD, fans, screen, etc), and puts the CPU and memory into a quiescent state where they have just enough power and clock cycles to keep them going. When you resume from sleep, you are returning power to all the unpowered items and away you go.

Hibernate writes the contents of RAM to your hard drive, then turns the computer off fully. If you have 2gb of memory, it writes a 2gb file (hence the amount of time it takes to hibernate and resume).

You can remove all power from a hibernated system. You could even take the hard drive out and put it into another system (of the same configuration) and start it up. If you take power away from a slept system, you lose your work and have to boot from scratch.

Hibernating will not slow down your computer while you're using it. It only writes out to the hard drive at the moment you tell it to sleep (fn+f12 on the thinkpad).

Under Vista there is also what is called hybrid sleep. Under this your ram content is written to the hiberfil.sys file, as with hibernate, but upon awakening, if there the connection to the mains has been maintained, the system wll awaken from sleep. But, current has been interrupted, it will recover from hibernation. The advantage is a much faster awakening normally, with the protection provided from hibernation in case of a catastrophe.

Hybrid sleep is enabled by default, but may be disabled if you wish.

Hybrid sleep was not enabled by default on my system and the Vista help file on the subject specifically states that hybrid sleep is not enabled by default. But I am thinking of trying it.

As far as whether using sleep while on battery power (for brief periods) is a good idea or not, I guess it depends in part on whether the power saved by a quick resume from sleep is equal or close to the power saved by using hibernation instead of than sleep.

Some of the sleep related problems people connected to a wired LAN are experiencing could possibly be related to the default setting that allows the system to be woken up by the LAN. This setting can be changed under network properties in device manager. I recall having read in some other threads that unchecking that box solves some problems.

You are correct and I was wrong. Hybrid sleep isn't enabled by default.

As for my sleep problem, it wouldn't stay asleep, was because the network adapter was set to awake upon demand. Once I disabled that I had no further problems in this regard.

When I leave my Thinkpad T61p in sleep mode it shuts down after a few hours and it stays like bricked, no lights even if you plug in the electric cable. If I want to boot I have to remove the battery and plug in the electric cable then led on the cover switchs on. I thought it could be the battery but I received a new one from Lenovo and nothing changed.

When I check the battery level it is normally over 40% and after a few phone calls to Tech. Support they have no clue about this issue.

Lenovo Thinkpad T61p 8891-CTO, 1 Gb Intel Turbo Memory, Nvidia Quadro 570M 128 Mb, 14.1 inch standard LCD, 2 Gb RAM, 100 Gb 7200 rpm Hdd, Windows Vista Ultimate 32 bits, latest BIOS and drivers...

HELP!

Hello,

pretty much since the last Windows Update, I'm not able to resume after sleep. It goes down correctly, but when turning it on again, only the three leds for A/C, Battery and "powered on" are illuminated. In particular, the HDD does not seem to become active which results in a dark screen an no other fix than holding down the power button.

I'm not sure though whether or not it is in fact related to the latest Windows updates.

Hi, Jo,

I'm not having any problems sleeping my T61p, and it has all the updates, too. I do have hybrid sleep enabled for it. (After pulling my XP R52 out of its sleeve a few times and finding it ether warm (still running because something prevented hibernation) or dead (same reason), I think that hybrid sleep in Vista is a great idea.

To enable it, you can muck around in Control Panel, Power Options, but it's easier to start an elevated command prompt (start, all programs, accessories, right-click command prompt and select run as administrator) and enter this command.

powercfg -h on

And this changes the indicator light behavior a little bit.

If you've set the laptop to sleep and the sleep LED is lit, it's really sleeping.

If you've selected hibernate, the sleep LED flashes until the hibernation is complete.

If you set it to sleep and the sleep LED has gone out, it timed out and hibernated itself.

And it just so happens that I wrote an article about this.

I did not have a problem with sleep mode until a couple of days ago..

A little research gave me a hint. I recently updated the video drivers with the latest from laptopvideo2go. This might've caused it. Especially if you say that windows updates were fine, this should be it.

But even after downgrading the drivers to the latest provided by Lenovo, the pad does not wake up...

Hate this machine..

Hi, Jo,

Love my T61p. You can try going back to an earlier snapshot. Unless you've disabled the volume snapshot service, Vista will have made a restore point each time you installed an update.

To do this, first close all other applications (because Vista will want to restart) and then press the Windows button and enter

system restore

Then, if UAC is active, select Continue.

In the dialog, click "Show restore points older than three days."

And pick the snapshot that you want to try to go back to.

It's a good idea to get friendly with restore points. I create one before installing ANY software. Here's the fastest way to create one in Vista.

1. Press the Windows key and type in “systempropertiesprotection”
2. If User Access Control is active, click Continue
4. Enter a meaningful name for your restore point
5. Click Create and watch as it makes the restore point
6. Click OK to close the System Properties dialog.

Good luck with this, and let us know what you find out.

Lamar

Thanks for your detailed help!

I did not do it this way though. I reinstalled the 169.09 nvidia drivers from laptopvideo2go which I think were the ones I had in use before upgrading.

Wakeup is now fixed again.. the price being old drivers which may cause issues with newer games.

Oh well...

danny_isr · #24 Post by **danny_isr** » Sat Nov 29, 2008 1:35 pm

i have similar problems with my T61p and had worse problems with my T43. so i woudnt say it's vista related.
the T43 run XP-pro. i have XP and vista64 on the T61.
maybe it's a MIcrosoft issue.
not sure what it is, but the wake up sleep thing is far from being perfect.
yes it works , but someone need to redesign this feature .
hardware or soft or both.

jo2008 · #25 Post by **jo2008** » Sun Nov 30, 2008 5:18 am

It sure is messed up.

With the original VIsta installation that came with the Thinkpad, I was also able to reproduce a BSOD when resuming from sleep. Haven't really followed the evidence trail, but it had either something to do with Logitech USB speakers or an external hard disk, both of which I did not turn off during the sleep phase.

I think I never owned a machine that was capable of mastering sleep & hibernation consistentl
