One suggestion that seemed to help people, albeit a strange one, is to go into the BIOS and Enable USB Wake Support.
I can confirm that this is not a Windows issue, as people have reported the same behavior on the 7373 with many flavors of Linux.
I'm fortunate that I can still wake my laptop from sleep mode using the Windows logo key on my keyboard.Ħ4-bit Win 10 Pro v1909 build 18363.535 * Firefox ESR v68.4.1 * Windows Defender v.3 * Malwarebytes Free v3.8.3ĭell Inspiron 15 5584, Intel GHz, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G SSD, Intel UHD Graphics 620Įdited by lmacri, 20 January 2020 - 11:26 AM. Sadly, turning USB Wake Support back on in my BIOS settings didn't fix my own sleep / hibernate problems, but that probably isn't surprising since I normally don't have any USB-connected devices like a mouse, keyboard or external monitor attached to my laptop. If you enter your own Service Tag on the USA support page for your Inspiron 7373 2-in-1 laptop at it will likely recommend the latest Dell Inspiron 7370/7570/7373/7573 System BIOS v1.15.0 (released 0). I installed the Inspiron 5583/5584 BIOS v1.9.1 (released 0) for my laptop model and noticed the user interface was quite different from my older v1.5.2 / v1.7.1 / v1.8.0 (i.e., check boxes have changed to on/off switches and I had to do a bit of searching to find the USB Wake Support and Block Sleep settings) and that USB Wake Support had been automatically disabled during my BIOS update. You might also want to re-check the USB Wake Support setting in your BIOS settings.
My laptop is still under warranty, but there seems to be something very odd about the drivers the Dell SupportAssist utility detects for my system (I think SupportAssist uses the Dell Service Tag for my laptop to look up my system components) versus the actual hardware devices that were installed at the factory. You might find some helpful clues in the reply I posted last night (1) in my Dell Community thread InspiWakes After 180 Min of Sleep (ACPI Wake Alarm). Update: Problem persists even with hibernation disabled But I really find the hibernation feature useful and without I am just fresh booting my computer more often anyway which is the problem the bug is causing. If I leave hibernation disabled I am not sure if the problem occurs. USB Wake Support has been enabled for quite some time. If you have any questions, feel free to post a comment. If you’re having other sleep issues, make sure to check out my post on troubleshooting Windows not going to sleep. You might also see some options under Wake Up Event Setup related to resuming from S3/S4/S5 by mouse/keyboard/USB device. The option in the BIOS may be called ACPI Suspend Type. You can usually tell this if there is an option to enable USB Wake Support or enable a sleep state higher than S1 (normally S3). If you are missing the Power Management tab or the box is grayed out, you need to go into your computer BIOS and make sure it supports wake over USB. In addition, sometimes the Allow this device to wake the computer box is grayed out and you can’t check or uncheck it. In some cases, you might not see a Power Management tab for some or all of your USB devices. If nothing else other than HID Keyboard Device shows up, then just disable it for that also. If you have a wireless keyboard/mouse and there is a USB transmitter attached to your computer, you will also need to disable this option for that device too. For example, you can also prevent the keyboard from waking your computer or the network card too. To prevent other USB devices from waking your computer, just right-click on them, choose Properties and go to the power tab. This will get you to the same dialog with the Power Management tab as shown above. Note that you can also get to this setting by clicking on Start and then typing in Device Manager.Įxpand Mice and other pointing device and then right-click on the mouse and choose Properties. Fixing this setting will prevent that from happening. Some high-end mice, like gaming mice, have high polling rates and high DPI, which means even the tiniest of movements will be detected and cause your computer to wake up. From now on, you cannot wake up Windows from sleep mode by clicking a mouse button or moving the mouse around. Click the OK button and click OK on all the other open windows too. In the second Properties window for your mouse, click on the Change Settings button on the General tab.įinally, click the Power Management tab and uncheck the Allow This Device to Wake the Computer box.
