View 1 RepliesI have a Dell Precision M4800, only a few months old. My docking station is a Dell E-Port Plus II, which came with the computer. Very recently, after an update to Dell Command Power Manager, whenever I dock my laptop to the docking station, Dell Command Power Manager will say 'The power adapter attached to your docking station is not recognized', and my system will run slowly. I have a power cord separate from the docking station that, when I plug in, will charge the laptop just fine. I am using Windows 7. What should I do? Is it the Dell Command Power Manager's failure?
View 2 Replies View RelatedI bought an RFB Dell Precision M4800 .... When I used my laptop in the ark. My keyboard hadn't been enlighten.
I tried follow some suggestion as: install Dell Feature Enhancement Pack v2.2.1
But I didn't find "Dell Keyboard Backlight Settings" on control panel as guidance.
Having a strange issue with the Touchpad on my Dell Precision M4800. When I disable it using the Dell software or using the Fn+F5 hotkey, it has a tendency to come back on after a random interval of time. I want it to stay turned off permanently, as I prefer to use the Pointstick exclusively.When using the Fn hotkey, I get a notification onscreen as well as a popup in the system tray saying "Touchpad notification: Your touchpad has been disabled." If I manually disable it through the Dell Pointing Devices software, I get the same effect, but without the notification. In either case, this works great... for awhile.But then the Touchpad inevitably turns back on. I often don't notice until suddenly my mouse cursor is behaving erratically, at which point I try to swipe my finger on the touchpad and sure enough, it's become enabled again.
However after some further experimenting it turns out the "random" aspect of this is not totally random and I can reproduce the issue quite reliably by furiously scanning my finger back and forth across the Touchpad for a few seconds. Inevitably, the touchpad will turn back on, and I will get the notification "Your touchpad has been enabled." No buttons or hotkeys are pressed, all I have to do is move my finger on the touchpad surface rapidly and within seconds of starting to do that, it will re-enable itself. Again, there is also a notification that it has been re-enabled when this happens, so the software is detecting my finger movements somehow, perhaps I am accidentally performing some "magic gesture" that compels it to re-enable the touchpad.
If I don't intentionally try to cause this, it still turns on eventually, but can take a long time, half an hour or more before it becomes enabled again. I assume it's the activity of my palms resting on it that will accidentally turn it on again in the same way as swiping my finger intentionally across the disabled touchpad. It makes no difference whether the Dell Pointing Device software is open or closed and this will happen when any application is open.
All I want is for the touchpad to be truly disabled permanently and not accidentally turn on in the middle of my work. But at the same time I'd prefer to leave the pointing stick enabled, so I can't simply remove the driver. So far I've been using an external mouse and disabling all internal pointing devices, which works ok, but like I said I am fond of the pointing stick, I'd prefer to be able to leave it on with JUST the touchpad disabled.

This laptop isn't even one month old.. this is sincerely frustrating as i have alot of important work saved on here...
-When I plug in the charger.. the battery light turns on for a second then the battery light turns back off.
-When I try to turn on the laptop with the charger plugged in.. nothing happens at all. When I try to turn on the laptop with just the battery without being plugged in.. the power button will light up for a second then go back off.
I've tried: taking out the battery and holding down the power light for 1 minute.. waited 30 seconds tried turning it on with the power chord with no prevail. holding Fn and turning it on and nothing
Some signs I've been seeing: only bad signs i've seen was before it just didn't boot anymore.. maybe twice out of the 6 last time i've booted.. as soon as i typed my password to get into windows it would just shut off. i'd jus reboot and it worked fine. when it stopped turning on.. after messing with plugging it in or not (i didn't know if the battery was dead) i was able to make it past the windows sign on screen.. was going to email myself all my work before it suddenly shut off on me again. the battery had maybe 1/3rd life before it died
I might have interchanged battery chargers with another older dell model laptop.. but i think only a few times at most.. it mostly sits at work on a docking station at work. i have a feeling i never did though. from what i've read it seems like the battery chargers are all compatible as long as it's dell.
I recently ordered Mushkin Enhanced Blackline 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model 997067 - Newegg.com to upgrade ram on DELL M4800. When installed it doesn't let the Laptop to boot. Newegg says this is compatible but the product doesn't.I'm sure I installed it properly. By any chance,did I receive a defective product ? or is the product incompatible unlike Newegg's Memory finder suggestion ? Newegg charges $15 restocking fee, so I would like to make sure i'm not doing something wrong before before returning it.
View 5 Replies View RelatedI'm a proud user of an M4800, but the constant fan noise bothers me a lot. I ordered it wit win7 but almost directly switched to win 8.1.
What I already discovered: In the event viewer I experienced a lot of MSI error events (every 11 seconds) .
Event filter with query "SELECT * FROM __InstanceOperationEvent WITHIN 10 WHERE (TargetInstance ISA 'Msvm_ExternalEthernetPort') OR (TargetInstance ISA 'Msvm_VmLANEndpoint') OR (TargetInstance ISA 'Msvm_SyntheticEthernetPort') OR (TargetInstance ISA 'Msvm_ComputerSystem') OR (TargetInstance ISA 'Msvm_VLANEndpointSettingData')" could not be reactivated in namespace "//./root/virtualization" because of error 0x80041010.
Events cannot be delivered through this filter until the problem is corrected. If I stop the Intel(R) PROSet Monitoring Service these events stop, but I wonder if the performance of network devices is not affected negatively:
The Intel(R) PROSet Monitoring Service actively monitors changes to the system and updates affected network devices to keep them running in optimal condition. Stopping this service may negatively affect the performance of the network devices on the system.
Nevertheless after this action CPU usage has dropped, but still too much fan noise while the system does nothing ;o(
I contacted support and they adviced me to reinstall with win7, but that is no option for me for the moment.
My power options are set to 'Quiet (Reduced Fan Levels)'
In the BIOS vA03 I could not find an option to lower settings there. and all latest drivers are downloaded and installed.
I have a Precision M4800 that has its USB ports stop working in two cases so far. First, if I use the card reader at all, it works to access files, but then when I try to eject the card, it shows neither an error nor the "safe to remove" message. the card stays in the list of drives even after it's unplugged. If another USB drive is plugged in after this, it isn't recognized.
The second case is after using an external USB 3.0 drive for a while, it can stop working. The drive shows up in the list of drives, but all the directories appear empty. Unplugging doesn't remove the drive, and new drives aren't recognized. Once this happens, shutting down the machine crashes after a few minutes with DRIVER_POWER_STATE_FAILURE in either USBSTOR.sys or O2FJ2w7x64.sys. Could this be a hardware problem? It seems like the USB controller is locking up and the other drivers are getting blamed.
I recently re installed my Dell Precision M4800 laptop. In the device manager there is a driver not installed " Broadcom USH" I already searched for it, and there is one : Dell ControlPoint Security Device Driver Pack, but this device is not (yet) supported. Is there a way to fix this? I did not get any recovery cd with my pc, only a few drivers, not this one.
View 3 Replies View RelatedBrand New M4800 with docking station - I have ordered two new (large) monitors.In the meantime I have two old squarish VGA monitors. Because I cannot get these set up right.
On a desktop PC, I have good resolution on these old monitors - one connected via VGA-VGA cable plugged into DVI adaptor, the other connected via VGA-DisplayPort.I tried to copy this on the new laptop - I plug in one monitor using the VGA -VGA to the VGA on the back of the laptop or docking station: result is laptop display plus VGA on terrible resolution that I cannot seem to change!
Second monitor - VGA -VGA lead, but nowhere to plug in, so I got the VGA-DisplayPort adaptor and tried plugging it into the laptop's DisplayPort socket (not on docking station) - it "sees" it, but then, in display settings software, it crashes.
WHAT I NEED:
(a) Laptop lid closed, two VGA monitors at decent resolution - OR -
(b) 3 monitors: laptop display plus two TGA monitors at decent resolution.
I own a Dell Precision M4800 Workstation running Windows 8.1 64-bit and the problem is that when I type text, no matter where (address bar, Office, iTunes, etc), and go to move my cursor immediately after, it takes about 3-4 seconds of me swiping on the touchpad to get it to move.

View 4 Replies View RelatedI recently updated my Dell m4800 to BIOS A8 with Windows 7 64. I had been using a collection of older power adapters from my previous Dell m4400 without any issues. After the update, wow. A huge performance hit if I do not have the 19.5 volt and 9.23 amp adapter connected.
The m4400 power adapter is 19.5 volt and 6.7 amp. Pretty close right? Not any more.
I do have it connected to a Dell docking station almost all the time. Just checked. They are both 6.7 amp.
What changed in BIOS A8 and what the deal is with the performance? Looks like I need to request a new docking station, but I'm not sure IT will believe my story.

The option for wireless is enabled in bios.
Another on my growing list of unwelcome "features" of this machine...
Around 20 seconds after logging in after a full reboot my Wi-Fi connection is dropped (having already connected during the boot/login).
I'm using the Intel software to manage the Wi-Fi connection and it says it can't connect because the hardware switch is set to off. This is obviously untrue.
Only solution I've found is to manually flick the hardware switch to OFF and then back to ON, then it automatically connects.
Seems like a BIOS issue if it's suddenly turning the adapter off for no reason. I'm already on the latest A07. Problem does not occur when hibernating and resuming from hibernation.
I previously let Windows manage the Wi-Fi connection but it never automatically connected at all, hence the switch to the Intel utility.
I have problem a with my Switch 10. The internet connection drops frequently. It is followed by the signal strength icon showing 'Limited'. I then turn off WI-FI and turn back on and it does not recognize any networks at all. I then go into network settings, run the troubleshooter and it does its stuff, re-setting the network adapter, and then informs me that it could not find an issue. After resetting the adapter it works fine again.I have tried uninstalling and installing latest drivers but the problem persists. The problem lies within the adapter itself or the driver.
My adapter shows as being REALTEK and i read on here of similar problems with the Broadcom adapter, which makes me think that the driver is causing the problem. Someone suggested that the Bluetooth was causing a conflict, so I removed bluetooth and it made no difference. (I have re-installed bluetooth. All drivers are latest ones.My switch is not a month old yet and this happens a couple of times a day. and am close to returning the product. I like it, but cannot put up with such an important issue as the internet randomly dropping.
I just bought this today and it will not connect to my WIFI. I have Netgear WNDR 4500 router. It does not see the home network.
View 2 Replies View RelatedI manage to pair my 2-in-1 pc Acer Switch 10 with an externat Bluetooth (bt) device only when the tablet is connected to my home wifi network. As soon as I disconnect from the wifi network, the pairing with the bt device is disabled. If I try to pair the bt device when wifi connection is off, the pairing succeeds just for a few seconds (1 or 2) and then it disconnects.
The support assistance of the bt device, since it actually manages to pair with the pc in such wifi wird conditions, suggested that it probably can be a problem due to the chip of the pc that probably manages both the wifi and the bt connections and is not able to manage them separately.

I opened my Vostro 1400 some time ago to clean it out, and put it back together again carefully. I also reformatted it recently.
Ever since, the wireless switch at the front doesn't seem to do anything when I press it all the way to the right. Before, it would show all wireless APs in the area, and their signal strengths, on the screen.
It seems my VGN-Z21WN wifi module is dead. Whenever I put the wireless switch on "ON", the led never lit up
Is this known issue ? Is there something I could try before sending it to Sony support center ?
My wireless card stopped working and I get the message that the radio is disabled. F2 is supposed to turn it on,but no longer does so. Tried reinstalling the wireless card driver, but that didn't work. I am told that I probably have a software conflict. How to find and correct the conflict?
View 2 Replies View RelatedI recently purchased an Acer Switch 11. I noticed that I wasn't able to adjust the display contrast, using the left/right arrows and "FN" key. Through a chat session, an Acer technician recommended that I reinstall the Intel VGA Driver through Acer Recovery Management. I followed his instruction, and it worked. However, later I noticed that I could not longer adjust the contrast. I could see the indicator move up and down in the upper left-hand corner of the screen, but the contrast wouldn't changed. I once again reinstalled the Intel VGA Driver, and it corrected the problem.
After re-installing the driver a second time, I decided I would leave the tablet plugged into the keyboard. Every fifteen minutes or so, I would unplug the display to see if the contrast changed. Based on my settings, it did change as desired. I did this for several hours. Later, I decided to remove the display from the keyboard. Initially, I was still able to adjust the contrast. However, after 10 minutes or so, I no longer could make adjustments. At that point, I placed the display back into the keyboard dock. I tried to see if it being locked into the keyboard was required in order to make contrast changes. It still didn't work. I then reinstalled the Intel VGA Driver and corrected the problem. I have kept it plugged into the keyboard, and I can still make adjustments.
My HP Pavilion notebook series G7-1135sd will not start. I get no response from the on switch. Some lights do come on but the screen does not light up. I have tried holding down the on switch for longer periods - without success. I have tried taking out the battery - also no success.

Dell lists this computer as a Precision M2800 (Early 2014) on the drivers site.
My girlfriend gave me a brandnew Aspire Timeline 1810TZ with build in G3 (UMTS) for Christmas. When i played around with the preinstalled system (Windows 7 Home Premium x64), I could use the hardware switch in the front of the chassis to enable/ disable the build-in G3-Module.
But as you know, the preinstalled OS are normally very slow, so i formatted the System and installed Windows 7 Professional x64. After installation of all drivers from the Acer website, the switch for enabling the G3 didn't worked anymore! I reformated again with Windows 7 Home Premium x64, but there was the same Picture: No, response from the G3-Switch.
The funny thing is: G3 and WLAN share the same physical hardware switch (you have to flip it to the left to enable/disable G3, and to enable/ disable WLAN you have to flip it to the right).
Flipping the switch to the right activated WLAN without any problem!
I have no idea how to fix this (tried every driver i could find).
Touch screen not working after reinstalled a win8.1. I deleted the Recovery Partition. So how to fix the touch screen?
