Dell XPS 12 :: Keyboard Has Stopped Working After Waking Up From Sleep
Nov 21, 2014
My keyboard suddenly stopped working after waking my computer up from sleep. The on screen and touch keyboard still function normally as well as the mouse touch pad built into the laptop, but the physical keyboard does not. The LED for the CAPS LOCK button wont even light up when pressed. The keyboard back lights however do turn on and off when the computer is powered on or flipped between tablet and laptop mode.
I have tried restarting the computer on several occasions as well as doing a complete shut down. I have updated all drivers and even uninstalled all of my keyboard drivers to no effect. I have tried running a diagnostic, but I either get an error that says the diagnostic could not run or that no data has been collected by the testing. All other scans of my computer show no issues.

I'm not sure if any other user has experience this issue. I did a lenovo update couple weeks back and since then my wireless adapter would not work after waking up from sleep mode. It shows that the wireless adapter is connected to wireless network but the internet would not work. The only way i can make it work is by disabling the wifi adapter by putting the laptop in airplane mode and then bringing it back out from it. Disabling and enabling the wireless adapter does a quick fix and does allow me to use the internet without any issue for the time being. i have also uninstalled and reinstalled fresh drivers from lenovo website, still having the same problem.

I have a brand new T540P with a Validity fingerprint reader.
Rougly 80% of the time, the Fingerprint reader is unresponsive at the windows login screen after waking the computer from sleep. It works 100% of the time when booting from an off position, however. Once logged in, it also works 100% of the time. The issue only arises when logging into windows.
Things I have tried
-uninstalling/installing device in device manager and finger print manager pro software
-setting fingerprints through both fingerprint manager pro software (lenovo) OR through the built in windows fingerprint control panel options
-disabling "allow windows to turn off this device to save power" in device manager.
I should note as well that I have another T540P that I ordered as a replacement. Both models experience the same issue.
Is this a platform wide issue affecting all T540P models?

My XPS (bios A05) always wakes up after sleep mode with the fan running full speed and never stops after that. This occurs even if the PC goes to sleep with fan off (ie low system load, low temperature). The only way to turn the fan off is a full reboot.

I've noticed a strange occurrence with my MBP (unibody late 2009 model, 3 weeks old).
It's happened since purchase and It's intermittent and hard to isolate, but I'd like to hear if anyone has noticed this too or a potential fix. It could totally be normal.
Essentially what is happening is that my MBP's fan will sometimes ramp up to around 2700rpm after waking from sleep (typical unloaded speed is ~1900rpm). It will then slowly speed down to the typical fan speed a couple minutes afterwards.
It seems that it occurs only in battery mode and when:
a) It is used on material surface, ie couch or bed OR
b) It is woken quickly after entering sleep
I haven't noticed this happening when plugged into AC, perhaps because it's always on a desk when on AC?
What I've done to try : resetting the PRAM, logic, etc, reinstalled the OS (in case a software issue).

Keyboard backlit stopped working (it used to work earlier). In BIOS the keyboard is now defined as a nonbacklight (BIOS was updated by L521XA13W.exe from dell.com/support/drivers), not sure how it was defined while working...
I've looked for a solution at community.dell.com/support-forums: - pressing Fn+F6 doesn't switch it on,- launching BacklitKB.exe from QuickSet says the backlight is on but it's not (I can adjust brightness, timing, turn it off/on but it still won't work),- reinstalling the QuickSet doesn't work,- Windows Mobility Center lists the backlit keyboard, but doesn't bring it on;- putting it to sleep and waking it up also doesn't work as well as restarting it.

We have purchased and deployed a number of Latitude E7440's and E7240's and we are running into an issue with some of the E7240's. When waking from sleep while on battery power, the machine will start to wake, the display will come back and I can move the cursor but within a second or two, the cursor will freeze and the machine will become totally unresponsive. This doesn't happen on AC. I've set the power plan to 1 minute and tested over and over again and it is reproducible every time. The only way to recover from it is to power off the machine via the power button and restart it.
Right now this is happening on the original end-user's machine and 1 other deployed E7240 we were able to get back and test. I have a couple of other E7240's deployed and I have an email out to the end users to bring them in so we can check them too.
I've upgraded the BIOS from A09 to A13. I've tried switching wireless control from Intel to Windows. I've updated to the latest drivers on the Dell support site.
Machines are i7, 256GB SSD with 8GB RAM running Windows 7(64) Enterprise

Really odd issue. My touchpad does not respond at all after I wake the computer from sleep mode. The mouse buttons do not work and the touchpad is completely impossible to get to move. The only solution is to shut down the computer entirely and turn it back on.
Does anyone else have this issue? I've re-installed the mouse drivers and it keeps doing it. There is no way to re-create the problem; it just happens totally randomly (and usually very inconveniently).

I have a HP pavilion G6 model number C0Y35EA#ABU. I had an automatic update for Windows 8 and my keyboard stopped working immediately after.I have checked device manager and it says there is no keyboard and gives a code of C24.If I go into setup before Windows the keyboard works fine so I know it's not a hardware issue.

I am trying to troubleshoot a E1-531-4836 the Right hand side of the keyboard has stopped working, and the touchpad does not respond properly either. I tried reloading drivers, a system reset, and I am left with the same problem. I have plugged a USB mouse and keyboard in, and I can sort of use the computer, I can not get all functions to work completely.

I have an edge 530, i've had it about 2 weeks running windows 7 64.I have found that on default settings its fairly slow at waking up, i made one change which was to the wireless card, i unticked the allow my system to turn off wireless to save power (so it stays on). this seems to have made an instant difference and the laptop now wakes a lot faster.
The problem now is with having that option unticked, when my laptop does wake up the wireless is off when it wakes and will not turn back on, i have to manually turn it on. If i leave the power save option ticked for the wireless card it does auto connect when my laptop wakes.Seems a little odd as i thought unticking the option to allow my laptop to turn wireless off means it should just stay on but it seems to be having the opposite effect.all i wanted was for my laptop to wake faster and the wireless either stay on or auto connect after it wakes.

I just removed the LED dashboard cover and then the keyboard in a LATITUDE E4300 and used some compressed air for a simple spring cleaning. after I carefully put everything back together, the following keys stopped working 9 O L .
I repeated the process a couple of times to make sure I didn't make any mistake, but still those keys don't work.

I have a Dell Inspiron 7000 series and 2 days ago Windows installed a critical update which stopped my keyboard and mouse working, I have had to do a system restore to get it working again but with it being a critical update I'm assuming I will need it.

Suddenly my FN stops working if the keyboard is on F1-F12 keys. No reaction when pressing it.
If I go into the settings and change default to something else, I can press FN until it again show F1-F12 - After that is stuck on the function keys?

I have an XPS 12 that is the 9Q33 Haswell based model. Every time I wake the ultrabook up from sleep mode, my sound no longer works. The services says that the windows audio service and the realtek audio service are running. But to get sound again I have to either restart both services or logout or reboot.

Is there a way to put my Inspiron 15Z laptop into sleep mode by using only the keyboard? I know that I can do it by using Alt - F4, but that method requires me to close all existing open applications - would like to do it directly and not have to close down everything.

I am not able to wake up my new laptop from sleep via USB mouse or keyboard. I would like to be able to do that because I usually keep my laptop lid closed, so the power button is not immediately accessible. I've searched the forums here and found similar issues with other models, and at least with the Inspiron 17R the problem was recently resolved with a BIOS update. I had no issues when using the same USB mouse and keyboard on an old XPS 8000.
Now for the details:
Model: Inspiron 15 (3521)
BIOS: A06
USB Wake Support: Enabled
Operating System: Windows 8 Enterprise 64-bit
Keyboard: Microsoft Natural Ergonomic Keyboard 4000
Software: Microsoft Mouse and Keyboard Center
Mouse: Logitech Performance Mouse MX
Software: Logitech SetPoint
If I go into Device Manager, and look at various devices, I see the following:
Human Interface Devices
HID-compliant consumer control device - no Power Management tab
HID-compliant device - no Power Management tab
Logitech HID-compliant Unifying device - no Power Management tab
Logitech Unifying USB receiver - no Power Management tab
Microsoft Hardware USB Keyboard - "Allow this device to wake the computer" grayed out
USB Input device - "Allow this device to wake the computer" grayed out
Keyboards:
HID Keyboard Device - no Power Management tab
Microsoft USB Natural Ergonomic Keyboard 4000 - no Power Management tab
Mice and other pointing devices:
HID-compliant device - no Power Management tab
Logitech HID-compliant Unifying Mouse - no Power Management tab
Universal Serial Bus controllers:
Generic USB Hub - "Allow this device to wake the computer" grayed out
USB Composite Device - no Power Management tab
USB Root Hub - "Allow this device to wake the computer" grayed out
USB Root Hub (xHCI) - "Allow this device to wake the computer" grayed out
If I go into an Administrator command prompt, I get the following:
powercfg /deviceenablewake "Logitech HID-compliant Unifying device": You do not have permission to enable or disable device wake.
powercfg /deviceenablewake "USB Root Hub": You do not have permission to enable or disable device wake.
From what I've been able to find online, I should be able to enable "Allow this device to wake the computer" in the Power Management tab of various devices in Device Manager, especially the USB Root Hub devices, and possibly the Logitech USB and Microsoft keyboard devices. I assume if I can get that enabled, things might work as expected.

I have recently updated the BIOS on my E530 laptop to version 2.08 (the previously installed version was 1.xx, probably 1.37 as far as I remember, but am not sure about the exact version..). After the update the laptop keyboard and touchpad stopped working in Windows.
The keyboard does, however, work in the BIOS and both (keyboard and touchpad) work when the computer enters the Windows-startup-screen (where it suggests to fix hard drive errors etc.).
I am using Windows 8 all along and before I never had problems with my hardware. Now both the keyboard and touchpad are recognized in Window's Device manager, but are known to have troubles. There is also a PCI Device recognized in the category "Other devices", but it's missing any drivers (I wonder if there is a connection..). All those three are recognized as such by the Lenovo Solutions Center as well.
I have tried reinstalling the UltraNav drivers, but it wouldn't work. Also, I've tried finding any possible configuration regarding my problem in the BIOS, but was unsuccessful. If I attach an external mouse or keyboard, they work. I really don't know what else to do to get my laptop's keyboard & touchpad working!
The complete description of my laptop is: ThinkPad Edge E530 (3259-HLG), running Windows 8 (x64).

I'm about two week in after purchasing a Dell XPS 13 (L322X)... I've begin noticing the keyboard backlighting fails turn on after resuming (opening the lid) from sleep mode. Depressing the FN with the backlight doesn't remedy only a system restart does. Could this be the result of flawed keyboard drives? If so how do I get the drivers?

So I have an Inspiron 17R SE 7720 that has all the latest drivers with BIOS A11 (Win 7 Ultimate x64)... I have all the power settings configured for correctly for sleep (no hybernate), however no matter what I try, I can't get the laptop to wake when the lid is closed via USB keyboard.
I'm using Logitech's Wave MK560 combo (unifying receiver) - both the keyboard/mouse have the wake option enabled in their hardware settings. I also have wake from USB enabled in the BIOS.
The interesting thing is that if I put the computer to sleep with the lid open, I can make it sleep/wake it from the Logitech devices. With the lid closed, I can only make it sleep - the only way to wake it up is to open the lid and press the power button.
Cliffs Notes:
Lid Open : CAN sleep/wake from USB Keyboard/Mouse
Lid Closed : Can ONLY sleep - won't wake unless I open Lid&press power button

I have an Inspiron 15R (5537) that has all the latest drivers with Dell BIOS A01 (Windows 8). I have the options for closing the lid set at "Do Nothing" for both battery and plugged in, however no matter what I try, when the lid is closed I can't get the laptop to wake via USB keyboard or mouse.
Both the keyboard and mouse have the wake option enabled in their hardware settings. I also have wake from USB enabled in the BIOS.
The interesting thing is that if I put the computer to sleep with the lid open, I can make it wake it from the keyboard or mouse. But with the lid closed, the only way to wake it up is to open the lid and press the power button.
Summary:
Lid Open : CAN wake from USB Keyboard/Mouse.
Lid Closed : Won't wake unless I open lid and press power button.
