[Kernel-packages] [Bug 1449357] [NEW] Thinkpad T450s unable to resume after suspended for a long time
Public bug reported: My laptop shows a black screen when resumes from suspend. I'm unable to log in with ctrl-alt-f1 then ctrl-alt-f7. I'm able to control the keyboard backlight, the LED on the power button still looks like the way the laptop is in suspend. I'm only able to log in by pressing the power button and power off. This issue only happens when I close the lid and leave the computer for a long time. If I close the lid and open it in around 1 minute, it resumes just fine. I have to press the suspend button in the drop down menu to suspend the laptop first, and then close the lid. In that case, the laptop resumes without error. I've set in the power settings to let the laptop do nothing when lid is closed, and that didn't change the problem. The laptop only has an Intel integrated graphics card. I've tried using the newest i915 driver from o1.org and the same problem persists. This same problem is observed in clean installs of 14.04LTS, 14.10 and 15.04. I updated to 15.04 from 14.10 using the built-in updater. The laptop runs the newest version of BIOS from Lenovo.

[Kernel-packages] [Bug 1449357] Re: Thinkpad T450s unable to resume after suspended for a long time

I disabled that in BIOS and resume from suspend started working just fine.

[Kernel-packages] [Bug 1449357] Re: Thinkpad T450s unable to resume after suspended for a long time
So I tested with 4.1rc and it also doesn't work with intel rapid start. I set the rapid start timer to immediate in BIOS and as soon as I close the lid and open it back up, I was unable to resume to where I was. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1449357 Title: Thinkpad T450s unable to resume after suspended for a long time Status in linux package in Ubuntu: Incomplete Bug description: My laptop shows a black screen when resumes from suspend. I'm unable to log in with ctrl-alt-f1 then ctrl-alt-f7. I'm able to control the keyboard backlight, the LED on the power button still looks like the way the laptop is in suspend. I'm only able to log in by pressing the power button and power off. This issue only happens when I close the lid and leave the computer for a long time. If I close the lid and open it in around 1 minute, it resumes just fine. I have to press the suspend button in the drop down menu to suspend the laptop first, and then close the lid. In that case, the laptop resumes without error. I've set in the power settings to let the laptop do nothing when lid is closed, and that didn't change the problem. I've tried using the newest i915 driver from o1.org and the same problem persists. This same problem is observed in clean installs of 14.04LTS, 14.10 and 15.04. I updated to 15.04 from 14.10 using the built-in updater. WORKAROUND: In BIOS, disable Intel Rapid Start Technology.
