Dell Latitude E7240 :: Freezing When Waking From Sleep On Battery
Feb 5, 2015
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
When I checked the battery status window in DELL Latitude E7240, I found 2 battery,Battery #1 it charged to 100% without any problem but Battery #2 is "not present",if there external battery available for this model or not? and if not, Why the battery status window showing two batteries in the settings?
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 had this issue a little more frequently lately, both in vista and ubuntu and i think it's a hardware issue. after putting the computer to sleep (vista) or suspend (ubuntu), upon wake up, the display does not come on, keyboard and mouse are unresponsive....
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'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).
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 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'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?
I will walk away from my laptop dell E7240 for 5 minutes and it will go back to log in page. How do I change that setting. Also after a time it seems to go to sleep and knocks me off VPN connection during a web presentation if I do not interact with mouse during web conf. I have to use ctl alt del to log back in but then my VPN is gone. How do I extend the time the laptop stays active?
A company bought laptop with model : E7240 & E7440, So those laptops come with Windows 8 product-key store on mainboard. I would like to get that number because those laptops werer installed Wiindows 7 from our Global IT but right now those laptops are transfering to new owner and Global license of Win7 is end. Is possible to get product-key from each laptop for downgraded the license to Win7 without re-install the OS ?
We have bought a bunch of Latitudes E7240 and deployed them with the new Dell Data Protection | Security Tools (DDP|ST).Now we have discovered that if you attempt to login with the wrong credentials the device (HDD) will be locked.This is expected as it is one of the purpose of having Disk encryption enabled BUT if a user accidentally lock the HDD by typing wrong credentials you would expect to be able to UNLOCK it with the admin password. (You create one when first enabling DDP|ST)
So, the user forgot he's credentials and the screen only shows "The device is locked, contact your administrator" and with NO OPTIONS what so ever! How do I, as the administrator unlock the HDD? Where do I type the admin password?
Original Win 8 Pro, then updated to 8.1 Pro, the back lit keyboard works OK. However since I refreshed the system due to the hangs up problem at start up, the back lit key board stops working. Re-updated the OS back to 8.1 Pro again still not solve the issue.Does the backlit key board need special driver ? The device manager shows the keyboard as standard PS2
I have just gotten an E7240 computer and have noticed that the USB ports on the back of my computer are disabled when the computer is docked which is a very unfortunate feature of this new computer model. It seems there are many people posting complaints about this feature on the internet. It basically takes a computer that has 3 USB ports and makes two of them rather useless. It is very useful if a USB receiver for keyboard and mouse can be plugged in to the back of the computer so that the mouse can be used easily when docked, but also when the computer is taken off the dock to go to a meeting room. This then leaves the side USB port available for devices such as wireless projectors when in the meeting room. Although this computer was designed to behave this way, I think that most users would agree that this is a critical issue that needs to be seriously considered and fixed by Dell as soon as possible assuming that there is not already a work around available.
My Latitude e7240 when docked onto the PR03X docking station, the power adapter that is plugged into the PR03X completely goes dead. The only way I can reset the power is by unplugging and replugging the AC adapter FROM THE WALL. Tried the spacer. Tried double powering (1 adapter into the PR03X and another adapter into the e7240). Also tried plugging the laptop on first without power, and when powering up the laptop, it would boot up 10x slower than normal and sometimes hang. Also tried multiple other PR03X just to be sure the one i have is not faulty. The same problem is repeatable. The laptop has the latest BIOS.
It seems there is a power mismatch of some sort that would cause a) the adapter to fail, and then b) for the laptop to run extremely slow because of what?Is the problem caused by a faulty docking port on the e7240? I assume the PR03X is compatible to the e7240??
I've recently taken delivery of an E7240 with the FHD touch screen option. I am generally quite impressed with the laptop except for one thing, the touch screen buzzes. The sound is similar to a hard disk working, a bit random .. not a constant noise. The sound will immediately stop when I put a finger on the screen though which makes me think it's related to the touch screen itself.
Rebooting etc. makes no difference... shaking the laptop, smacking it (gently) etc. has no affect.....
I realise these laptops are new so perhaps there isn't much experience out there...
Just started using brand new Latitude E7240 and connected to E-port docking station. When booting an error pops up as below: The battery currently attached to the system will not supply enough power to dock for it to function. Please attach AC power to the dock for it to function normally
F1 - continue
F2- change setup options
The Laptop and the dock stations are brand new. This is only happening with the 7240's.
We have several Latitude E7240's on our network. They are configured with Windows 7 x64. We have been having trouble with this particular model in regards to wireless connections.
When the laptop is powered on and the user logs in, the laptop connects to the wireless network, however it is not getting an IP address from the router. It sticks at "limited connectivity", and gives itself a "169" IP. It stays that way for about 5 or so minutes then finally connects.
The WLAN drivers are already to the latest version, and to "bandaid" the issue, I have to uninstall the Wireless NIC drivers then reinstall them.
At first I was thinking it may be a router issue (Which is a Sonicwall TZ210W), but it can't be because its wireless devices of differing models have no problem connecting and getting an IP address. Also, it starts working once the drivers are reinstalled (though I'm not confident this is a permanent fix).
All the E7240's have the Dell 1506 Wireless card, and are all and originally were) on driver version 10.0.0.268, A02. Also, I have tried turned off any power management settings of the WNIC prior to the driver reinstall.
The USB ports on my new E Port II docking are not working with my new Latitude E7240 Laptop. Full configuration of the laptop is below. Talked with Dell and they sent me a replacement docking station but the same issue surfaced. Looked at the Device Manager and no extra USB ports show up when connected to the docking station. The side laptop USB works fine when the docking station is connected.
We are running more than200 dell computers in our company. lately we purchased E7240 for some users but it looks like the AC adapter does not work with the Dell E-Port docking station we have and that cause the USB hubs not to function at all.
Currently the workaround is to plug the AC adapter to the laptop instead of the docking station.
Our BIOS is updated to the latest version. also a message comes up when the ac adapter connected to the docking station before the windows boot up saying the ac adapter won't charge.....
When one turns off the Bluetooth adapter from the tray icon, the tray icon disappears. In order to turn the BT adapter back on, it appears one must go to the Device Manager to re-enable the BT adapter. This is inconvenient and not awfully intuitive for a usual business end-user. In the past the BT icon in the tray would remain, but turn color to indicate it's off. And the end user could right-click it and turn it back on when needed.
Currently it appears, turning off the BT adapter, actually disables it and it "disappears". Is there a way to simply turn the adapter off and more importantly back on without having users get into the device manager from their standard user accounts?

I have a dell Inspiron N5110 which is just over a year old. I upgraded to windows 8 not too long ago and my laptop has been just fine until today. When I close the lid or do anything to put my computer to sleep, it freezes up. The power button light stays solid and it seems like the computer is stuck. The only way to get it to do anything is to hold the power button down. My bios is updated to A11 which is the latest version. I don't know what else to do. Seems like I've tried everything but I can't figure it out.
