Why does my computer not turn back on after I suspended it?

If you suspend or hibernate your computer, then try to resume it or turn it back on, you may find that it does not work as you expected. This could be because suspend and hibernate are not supported properly by your hardware.

My computer is suspended and is not resuming

If you suspend your computer and then press a key or click the mouse, it should wake up and display a screen asking for your password. If this does not happen, try pressing the power button (do not hold it in, just press it once).

If this still does not help, make sure that your computer's monitor is switched on and try pressing a key on the keyboard again. As a last resort, turn off the computer by holding in the power button for 5-10 seconds, although you will lose any unsaved work by doing this. You should then be able to turn on the computer again.

If this happens every time you suspend your computer, the suspend feature may not work with your hardware.

None of my applications/documents are open when I turn on the computer again

If you hibernated your computer and switched it on again, but none of your documents or applications are open, it probably failed to hibernate properly. Sometimes this happens because of a minor problem, and the computer will be able to hibernate properly the next time you do it. It might also happen because you had installed a software update which required the computer to be restarted; in this case, the computer may have shut down instead of hibernating.

It is also possible that the computer is not capable of hibernating because the hardware does not support it properly. This might be because of a problem with Linux drivers for your hardware, for example. You can test this by hibernating again and seeing if it works the second time. If it does not, it is probably a problem with drivers on your computer.

My wireless connection (or other hardware) does not work when I wake up my computer

If you suspend or hibernate your computer and then resume it again, you may find that your internet connection, mouse, or some other device does not work properly. This could be because the driver for the device does not properly support suspend or hibernate. This is a problem with the driver and not the device itself.

If the device has a power switch, try turning it off and then on again. In most cases, the device will start working again. If it connects via a USB cable or similar, unplug the device and then plug it in again and see if it works.

If you cannot turn off/unplug the device, or if this does not work, you may need to restart your computer for the device to start working again.
