So basically I was using my laptop and decided to put it to sleep by pressing the power button. But i realised it was not responding, so I decided to shut down. Now, when I press the power button nothing happens. The charging light still works when it is plugged in. Somehow I managed to turn it on now and now if i try to put it to sleep using power button, it does not work
I have an Acer Swift 5 whose battery can't be removed
1. Go into "Control Panel" and click the "Power Options".
2. Next to the plan that is currently selected click "Change Plan Settings".
3. Now click "Change Advanced Power Settings".
4. Open the "Sleep Setting" and find "Hybrid Sleep"
5. Change/set it to allow.
6. Now click "Apply" and then click "OK".
7. Finally shut down and power up the computer.
Try updating the power management drivers.
Before doing the following, make sure that the laptop is using the most current version of the power management software. If not, update the drivers. Follow these steps:
1. Go to "Control Panel" and then click "Device Manager".
2. Double click and open "System Devices".
3. Right-click "Microsoft ACPI-Compliant System".
4. Now choose "Update Driver Software".
5. Carefully read all the instructions onscreen.
You may wish to also repeat these instructions, but right-click "Microsoft ACPI-Compliant Embedded Controller" in Step 3. (if located on your system)
If this doesn't work, you may need to go to the laptop manufacturer’s website and search their support section and locate any new power management drivers for your laptop make and model.
IMPORTANT NOTE: Do not remove any ACPI entries. Doing so may disable some of your laptop’s power management features, such as the ability to put it to sleep by pressing the Power button. It is also a tad complicated to reinstall those features, so best to avoid the problem all together.
