Lenovo T400 / T500 :: T500 Does Not Wake Up From Sleep Mode
Feb 17, 2010My T500 (2241-3XU with Win 7 64 bit Ultimate) has never been able to wake up from sleep mode after lid is closed. I finally reverted to using hibernate but was just wondering if there is a new fix that I am not aware of. I tried to find info a couple of years back before switching to hibernate.

Oct 31, 2008I can only get a 100 Mbps wired connection (not 1 Gbps) on my T500. I am connecting to a Net-gear GS605 switch. I have tried using exactly the same port and cable that gives 1 Gbps on another computer (a Dell XPS 420) but the T500 will still only connect at 100 Mbps. Both computers are running Vista Ultimate. I have tried changing the Advanced/Link Speed & Duplex setting (in the Intel 82567LM device driver) from Auto Negotiations to 1.0 Gbps Full Duplex but this does not work.

Jan 19, 2014I got a new T440s about 2 weeks ago and sometimes it doesn't wake up after it goes into sleep mode. It gets stuck on a black screen and the mouse cursor is visible, but moving the mouse or pressing keys on the keyboard fails to wake it up. When this happens, I have to restart the computer by holding down the power button for 10 seconds. I am running Windows 7 Professional 64 bit and hybrid sleep is off. I'm just really confused because sometimes it wakes up perfectly and sometimes it doesn't.

Dec 30, 2013I just bougth the T440 and I have two main problems related to sleep mode, which both seems to happend randomly.The most common problem is that when I close the lid (the action suppose to activate sleep mode), the computer seems to freeze during the time it is going to sleep : The red light is still on as when the computer is in 'normal mode', but there is no display and the keyboard seems unresponsive. I have no choice but to restart the computer.
Sometimes the computer seems to enter in sleep mode correctly (the red light slowly goes on and off, which according to the manual indicates that the computer is in sleep mode), but when I open the lid, the screen remains black and I can see nothing but the mouse. I have no choice but to restart the computer.
It also happened once that the above problem (the second one) kept occuring even after multiple restart of the computer. The only way I could solve it was by using 'windows safe mode'. As the problems occur randomly, I am unable to say if they were already there when I received the computer, or if they started to happen after the few windows updates/software installation I did.
Lenovo T400 / T500 :: T430 Being Very Slow After Sleep Mode
Dec 25, 2012I have a T430 that is a couple of months old. I've had this problem from the very beginning. Decents specs (have a Dell laptop with same specs and it never has this issue).
Processor: Intel Core i5-3320M CPU @ 2.60 GHz
RAM: 4GB
Basically, after every time the laptop is in sleep mode for more than 30 minutes, once I open up the laptop and log in, there is a period of 3-4 minutes where it is EXTREMELY slow. The computer lags ridiculously...
Lenovo T530 T400 / T500 :: HDD In Ultrabay Go Into Sleep After Some Time
Apr 9, 2013Lenovo T530. Power settings of Windows 7 and in Lenovo power Manager say that when laptop is plugged to AC adapter - NO SLEEP. But i hear how hdd stops down after some period of time and spinning again when there is a data read or write. That`s quite annoying, especially when primary storage is ssd drive. How to get rid of this "feature"?

Lenovo T400 / T500 :: T440 Fn Ctrl Reverting After Sleep Mode
Feb 27, 2014I have a T440, and I've set in BIOS to swap places for fn and ctrl. This works great until the machine goes to sleep or similar. After awakening the machine the keys are back to their original setting, with fn being fn, and ctrl being ctrl.
I havent explored this in detail but just found the machine sporadically losing the setting, but never while I'm working on it. So either from sleep or from locked screen.
I always use FnLk as well and that is also lost when this happens. I have to restart to get back the setting for fn-ctrl swap, but FnLk i can just enable,
I run Windows 8.1 on my T440.

Dec 13, 2013I’ve had the T430s for about a year. Whenever the laptop goes into sleep/hibernate mode, I hear a high pitched hum come from the bottom back section of the laptop. It also becomes noticeably louder when I unplug the AC adapter. I've put my ear to the laptop to try to identify where exactly the noise is coming from. I attached a picture with the general vicinity circled.
I don’t think I explained the issue to the repair centre properly. They ended up replacing the fan the first time I sent it in for repair. The second time I sent it, they replaced the system board. However, it continues to emit that high pitched hum.
Am I being too sensitive to the noise or is this something that can be fixed? I’m just past my warranty and I’m afraid if there is a problem that isn’t identified, I’ll be stuck with it for the next few years.

Lenovo T400 / T500 :: T440S OSD Brightness Control Failure After Resume From Sleep
Jun 19, 2014I have owned a T440S since late 2013.
Relevant Details:
T440S
Model : 20AQCTO1WW
OS : Windows 7 professional (original installation by Lenovo)
Latest Drivers installed as of June 2014 - including HotKey and Power Management
HotKey ver : 8.30
Power Managment : 6.65.1
Since receiving this laptop, OSD birightness control has always failed to work, i.e. does not appear on the screen when using the Fn+F5/F6 key combination nor does it control actual screen brightness AFTER FIRST resuming from sleep mode.
Sequence of steps that demonstrates the above symptom:
1. OSD brightness works fine after reboot
2. Putting the machine to sleep (I do not use hibernate) for a duration longer than a few minutes
3. Open lid the first time, hit Fn to resume machine
4. Pressing Fn+F5/F6 key combo does not display the brightness slider nor does it control brightness
5. Closing the lid and opening it again, causes OSD brightness slider to flash briefly and is now fully functional using Fn+F5/F6 keys
Your tech department should easily be able to re-create this issue on any stock T440S/Win7pro machine, as I have seen others comment about this very issue across other T440/OS variants.
Lenovo T400 / T500 :: T540p - Display Inactive After Wake From Sleep Using Windows 8.1
Oct 30, 2014Windows 8.1, 64bit, all drivers up to date, Nvidia 730m, intel 4600. Fairly new issue (couple of months), laptop wakes from sleep but display does not function, everything seems to be working normally during, just no display. Forced to hard restart.
Just avoiding using sleep mode for now. Seems to be a software issue, upgraded to 8.1 when purchased almost a year ago, worked fine until recently.
Lenovo T540p T400 / T500 :: Intel HD Graphics Brightness And Sleep Not Working
Dec 4, 2013So, I just got my shiny new T540p with a 3K display and Win Pro 8 installed. I promptly upgraded to Win 8.1 Pro and now I have a problem with the Intel HD Graphics. Basically, the system will not turn the display on after a sleep and I can't adjust brightness.
I tried downloading the drivers from the support page, but they reference a Intel(R) HD Graphics 5000 card, whereas my system says it has a Intel(R) HD Graphics 4600 installed. When I try to run the driver install anyway, I get a message saying that my system does not meet the minimum requirement for installation (?).
I tried manually installing the Intel(R) HD Graphics Family driver instead. This fixed sleep and brightness control, but then all things 3D was completely messed up (like buttons in Skype and Chrome).
Lenovo T400 / T500 :: T440s Windows 7 Pro Loses WiFi Connection After Sleep 7260AC
Feb 6, 2010I keep having issues waking up from sleep with my T440s. It WILL NOT connect to wifi and the wireless adapter under windows adapter settings disappears. Only thing that fixes this is a reboot. I have removed "allow windows to turn this device off" under wireless settings.

Software: Lenovo Access Connections
I do not use windows to connect to WIFI. I have dedicated profiles for each of my wifi networks at home and work.
Lenovo T400 / T500 :: T440s - Wireless Adapter Is Not Working After Waking Up From Sleep Mode
Feb 26, 2014I'm not sure if any other user has experience this issue. I did a lenovo update couple weeks back and since then my wireless adapter would not work after waking up from sleep mode. It shows that the wireless adapter is connected to wireless network but the internet would not work. The only way i can make it work is by disabling the wifi adapter by putting the laptop in airplane mode and then bringing it back out from it. Disabling and enabling the wireless adapter does a quick fix and does allow me to use the internet without any issue for the time being. i have also uninstalled and reinstalled fresh drivers from lenovo website, still having the same problem.
View 7 Replies View RelatedLenovo T400 / T500 :: T540p - Fingerprint Reader Not Working Upon Waking From Sleep For Windows Login
Mar 11, 2014I have a brand new T540P with a Validity fingerprint reader.
Rougly 80% of the time, the Fingerprint reader is unresponsive at the windows login screen after waking the computer from sleep. It works 100% of the time when booting from an off position, however. Once logged in, it also works 100% of the time. The issue only arises when logging into windows.
Things I have tried
-uninstalling/installing device in device manager and finger print manager pro software
-setting fingerprints through both fingerprint manager pro software (lenovo) OR through the built in windows fingerprint control panel options
-disabling "allow windows to turn off this device to save power" in device manager.
I should note as well that I have another T540P that I ordered as a replacement. Both models experience the same issue.
Is this a platform wide issue affecting all T540P models?
Lenovo T400 / T500 :: ThinkPad T520 Reconnects To WiFi After Wake Up From Sleep But Web Pages Load Very Slowly
Oct 20, 2013My Thinkpad T520, Windows 7 Pro takes over a minute to load any webpage after waking from sleep. The wifi icon shows that the network has connected to the internet after about 10 seconds from wake up. But if I attempt to use a browser to load any webpage, I must wait nearly a minute before the page will load. After that, pages load quickly.
This problem occurs in multiple browsers (FF, IE, Chrome). I am using Intel Centrino Advanced N-6205 wireless adapter. I've updated the wireless driver and BIOS. I've cleaned out my registry using CCleaner, and I've defragmented.
One bit of advice I've read that I've tried from these forums does NOT work: Uncheck from Device Manager under the Power Management tab for my wireless adapater the option to Allow the Computer to Turn Off This Device to Save Power. Unchecking that option (which would seem to keep the driver on) makes the problem worse because the wifi will not reconnect at all.
Lenovo T400 / T500 :: T540p Battery Drain In S4 Sleep State After BIOS And Intel WiFi Driver Update
Aug 17, 2014On my T540p, I configured the rapid start technology according to [URL] ....
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days. I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to [URL] ....
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
How could this battery drain be avoided?
Acer :: 1410 Wakes From Sleep By Itself, But ONLY When Lid Closed
Oct 18, 2009My 1410 has a very strange problem. If I put it to sleep with the lid open, it will properly stay asleep for hours and hours.
However, if I then close the lid, it will always wake up within 5 minutes (I can tell by the status lights). This happens regardless of the lid-closing action I have specified in Windows (hibernate, sleep, none).
If I tell it to hibernate on lid-closure, it will hibernate properly. If I tell it to sleep on lid closure, and close the lid, it will go to sleep and then quickly wake up again. What the hell could be doing this, and how can I fix it?
The laptop is a bone-stock aspire 1410, running windows 7-64, with up-to-date drivers and the latest BIOS (happened with old BIOS too).

View 1 Replies View RelatedDell :: SXPS 1645 Unexpectedly Wakes Up From Sleep Or Hibernation In Windows 7
Jan 18, 2010For the last several days my Dell SXPS 1645 laptop running Windows 7 Professional randomly wakes up from either Sleep mode or Hibernation mode at any time during the day. The most it seems to stay off is for ~6 hours. It does not happen when I properly shutdown the PC. I checked the task scheduler, and nothing is scheduled to run at most of the times it wakes up, and none of the tasks are set to wake up the PC if scheduled to run. In the system logs, Windows 7 recognizes that it was waked up, but the "Power-Troubleshooter" event entry looks like this:
The system has resumed from sleep.
Sleep Time: ‎2010‎-‎01‎-‎18T11:10:00.659235300Z
Wake Time: ‎2010‎-‎01‎-‎18T17:43:26.545117000Z
Wake Source: Unknown
Any idea what could be causing this? I'm positive it's not a "Wake-on-LAN" feature as that's fully disabled and I'm only using WiFi anyways. I'm not sure if this happens when the laptop is only plugged in or if it happens on battery as well. (I'm continuing to see if there's a trend on this one)
Some background info: I'm running the original Dell build on the laptop with some of the bloatware removed via Control Panel. I've modded the ATI driver to the latest Catalyst version, which does seem to record the odd event error shortly after power-on (I noticed it when checking the power on event logs)... not sure if that's related.
Dell Inspiron 3537 :: Windows 8.1 Update - Laptop Never Wakes Up After Going To Sleep
Jan 9, 2014I just bought my new laptop. I have it for around 10 days. Everything was ok at first but after 3-4 days I decided to update to Windows 8.1. After that the laptop never wakes up after going to sleep no matter what I do.
It seems that others have the same issue. I tried uninstalling and reinstalling both display drivers, I removed a bluetooth device that had an error with 8.1 but I couldn't resolve the wakeup problem. I ran the power troubleshooter, nothing. Hybrid sleep in advanced power settings was already off.
It's really frustrating to have to do a hard reset everytime
My machine is an Inspiron 15 3537, i7 4500U, AMD 8850M, 8GB RAM, 1TB HD.
HP Pavilion Dv6-6145dx :: Fingerprint Reader Often Stops Working After Laptop Wakes Up From Sleep
Nov 2, 2009I am convinced that the fingerprint reader is fine. There must be some issue with the driver perhaps, something incompatible with a recent Windows 7 software update?
Laptop working fine. I put it to sleep when I'm done and use the mousepad to wake it up. The fingerprint reader LED will blink, and I can swipe my finger to log on.At some point, after a few times of putting laptop to sleep and waking up, the fingerprint reader does not respond. No blinking LED. I swipe my finger and the reader does not respond at all -- doesn't even tell me that there was a bad read.If I log off and log back on again, no change. However, if I do a reboot, everything is fine--the fingerprint reader is working again.
My system is an HP dv6-6145dx. I am running Windows 7, with latest updates. The built-in fingerprint reader is running on HP Simple Pass 2011 v5.1 and Validity Sensor driver version 4.3.205.0. When I attempt to launch the Simple Pass interface, it loads the database but then the application vanishes. I tried uninstalling and then reinstalling the software, but this does not make any difference with the issue I noted.
Lenovo T400 / T500 :: No Display After Installing Win 7 Home Premium On T400
May 4, 2014Bought a refurb T400 and installed a PNY SSD in it. It POST's okay and I can access bios. I can also read/install Linux from DVD just fine.
Trouble is when I insert my win7 home premium DVD into the drive and boot it, I get POST and then I get a black screen. It seems to be reading the drive and when I interrupt with the Esc key or open the DVD drive, I get a Windows menu explaining that the installation has been interrupted.
I've looked at the bios options and can't see anything obvious that should be changed.
