My laptop freezes when it automatically goes to sleep (or hibernate) due to Control Panel's Power Options settings. I can not get the laptop to wakeup by pressing any keys including Control
+ Alt
+ Delete
. Briefly pressing the power button does nothing. I have to hold the power button down for 4 seconds to force the laptop to power off. When it boots up, Windows complains about the laptop not being shutdown properly.
The laptop freezes when I manually put it to sleep (or hibernate) even when automatic sleep (and hibernate) is disabled in Power Options.
Manually sleeping (or hibernating) freezes the laptop even if the laptop is not docked and running on a battery. The only thing connected to the laptop when undocked is my wireless (non-Bluetooth) mouse.
Manual sleep (or hibernate) works 1 time and the second time will freeze the laptop. After a reboot, I can repeat the process (i.e. the first time works and the second time freezes).
Edit 2014/07/15: I replaced the SSD with the original HDD. When I manually put the laptop to sleep and wake it back up, the laptop will freeze a minute or two later. The screen is on and I can see the desktop but nothing responds. I don't even get a chance to put it to sleep the second time.
Docking and undocking the laptop has no effect on the laptop if the Power Options are not set to put the laptop to sleep if the lid is closed.
There are 3 phases to sleep. The first phase lasts a few seconds and flashes the disk light several times with many flashes being very bright. The second phase lasts a few seconds and doesn't flash the disk light at all. The third phase lasts a lot of seconds and keeps the disk light on the entire time but not very bright. The laptop always freezes during the first or second phase... I can't tell which.
I can start and exit Process Explorer several times without freezing the laptop. See this question for more details. If I put the laptop to sleep and wake it up, then exiting Process Explorer will freeze the laptop. It seems the laptop/OS gets into a state after sleeping that anything can cause it to freeze.
I thought about booting into Safe Mode and try sleeping from there. Unfortunately, I didn't see a Start menu option to sleep or hibernate while in Safe Mode.
I tried several other things and put them as answers so that others can upvote them and we can see what generally works.
Here is the configuration of my laptop:
- Dell Latitude E6430

- Intel HD Graphics 4000
- Video BIOS version: 2158v12
- 16 GB of RAM
- 500 GB SSD SATA (Samsung 840 EVO)
- Firmware version: EXT0BB6Q
- Windows 7 Professional 64-bit Service Pack 1 (build 7601)
1The laptop has a problem with both sleep and hibernate. From the start menu, I can click on sleep and the laptop will freeze. After rebooting, from the start menu, I can click on hibernate and the laptop will freeze. – Nathan – 2014-05-20T17:54:17.813
I assume you have all drivers updated, right? Sleep/hibernation issues can occur easily whenever a driver isn't prepared for alternate power states. – Doktoro Reichard – 2014-05-20T19:16:07.967
I use Windows Update and Slim Drivers each week and install everything. If there is a driver problem, how do I figure that out? If a user-mode process freezes, then I can attach a debugger and get a call stack. From the call stack, I can then figure out the problem. Is there something similar I can do here? Is there logging I can enable and check? – Nathan – 2014-05-20T19:21:13.437
I don't believe there is a clear way to check if a driver fails entering into sleep and determining what driver it is. I'm not familiar with Slim Drivers, but from the description I searched, I can ask you this: using the default drivers (i.e. those that originally came with your machine) did you have any problem putting your computer to sleep? If not, and you don't need the updates, then don't. Not every driver update is necessarily welcome and in some cases, some functionality may be broken when updating. – Doktoro Reichard – 2014-05-20T19:26:35.567
I got the laptop early April 2014. It always had a sleep (and hibernate) problem. The first thing I did was update the drivers. The sleep (and hibernate) problem continues. So, the original drivers don't help. – Nathan – 2014-05-20T19:28:36.477
Your installing Windows 7 drivers, that specifically support Windows 7, correct? Its unusual for new hardware to come with Windows 7 hence the reason I bring this up. – Ramhound – 2014-05-20T23:13:53.710
Yes, I am installing drivers that specifically support Windows 7. – Nathan – 2014-05-20T23:46:03.310
I (myself) would avoid these automated driver installs, just because I do not want changes occuring that I do not manually test right after they go in. I agree with the drivers suspect, so Next thing might be to stop this automated changing and go direct to the manufacture sources for what may be older driver versions, but better tested one. chipset for one? – Psycogeek – 2014-05-21T02:35:16.213
The chipset driver is from the manufacture source. In fact, all of the drivers installed through Slim Driver's help are from the manufacture source. Slim Driver just makes it easy. – Nathan – 2014-05-23T00:44:55.150
