My T580 won't wake from sleep mode if I close the lid, press the power button, or tell Windows to enter sleep mode. The power button and lid lights pulse like they do when in sleep mode, but I can still toggle the mute/caps lock/num lock/backlight lights on my keyboard. The fan is usually at full speed too.
In order to get the laptop to turn on, I have to either use the reset button on the back, or hold the power button for 20 seconds. I haven't observed the issue while the laptop is plugged in.
I can't afford to lose any work that I have open, or wait for all my programs to load, but I've never enountered this behaviour so I can't fix it. If it's a Windows 10 issuse, then I have to re-install the OS. I'd like to avoid doing that if the issue is with the laptop.
What do I do?
